One of the advantages of being an equipment reseller is being able to play with pretty much every scanner on the market without having to own them all. Last week I had just such an opportunity with the latest offering from Zoller + Fröhlich, the Z+F 5010C. The 5010C is essentially the 5010 (also formerly branded the Leica Geosystems HDS7000). The “C” stands for Camera as this unit is the first Z+F scanner to come with an integrated onboard camera. While this is nothing new in scanning, it is new to Z+F. Fortunately, they were paying attention to the complaints that many of us expressed about the experience of using and results obtained from most onboard cameras. By correcting many of these problems Z+F have produced one of the best systems for capturing RGB scan data that I have used.

For starters, the system does not image the mirror. The camera lens is mounted on the opposite side from the rotating mirror so that it takes a “direct” image. Most notably, the unit can capture High Dynamic Range (HDR) imagery. For the purposes of documenting a site nothing is better. The composite pano is made from 42 images and it normally takes just under four (4) minutes to capture those images. Each image is composited from multiple images of differing exposures that are taken from the same area (thus making it an HDR image). The results are stunning – nothing is too dark or washed out even when there are sunlit windows and shadows in the same frame. In the past I had to use a DSLR, a Nodal Ninja, and a couple of types of software to produce HDR panos. Even after doing so, you still had to manually texture map the point cloud. This was time consuming, mind numbingly repetitive, work that is now accomplished with a few mouse clicks in Z+F’s LaserControl software. It still takes a bit of time but it’s background processing time instead of manual labor and I’m all for that! The only complaint that I have about the camera system is the order in which the images are taken. The unit takes the images in a circular pattern starting at the lowest elevation and increasing the elevation of the camera lens after each 360° rotation. This means that staying out of the images is a bit of a dance that requires you to circle the scanner four or five times while the images are being taken. Having the images taken in the vertical with a horizontal movement following each vertical stripe would certainly help to keep the field personnel out of the images.

The range noise and accuracy are on par with what we’ve come to expect from Z+F (≤1mm linearity error, range noise 0.2 mm – 2.2 mm at <50m). The upgrades are from a class 3R to a class 1 laser while increasing the range to 187 meters. Compared with the 5006 series they have dropped the “high” and “low” power settings and moved to a series of settings that allow the user to select “density” and “quality” settings. Essentially, an increase in the “quality” setting doubles the scan time and reduces range noise to provide a cleaner looking point cloud. The batteries lasted about three hours each and charged at about the same rate so that you could rotate them and get in a full day’s work. The 5010C will also operate as a profiling scanner. As operating in this mode requires some accessories (IMU, GPS, etc) I won’t go into it here except to mention that it will definitely decrease the aforementioned three hour battery life. Scanning speed is listed as 1,016,000 points per second as with most scanners the actual collecting speed is significantly reduced. Scan times were on par with other scanners of the same caliber (5006 series, Leica P20). Full technical specifications are available on Z+F’s website.

Registration is also improved with a firmware tool that uses plane matching to aid in registration. After each scan is complete, the user views a 2D plan view of a cross section of the point cloud (at the scanner’s 0 elevation). If multiple scans have been taken, those positions will also be visible. The user can then drag and rotate the last scan’s data to match the previous scan data. Essentially you line up walls and other vertical shapes. It’s called “plane” matching as even complex shapes are reduced to a series of planes similar to a decimated mesh. Each of these surfaces can be used as a constraint. One hardware addition that greatly aids in this is a mark on the base of the scanner that denotes the direction of the “0” position or the false Northing if you will of the unit. If you always point this mark at your last position you can simply rotate the arrow on the onboard screen to point back at the previous scan position for a quick alignment. This alignment is not the total registration but simply a way to get the clouds close so that registration engine in LaserControl can quickly finish the job. Alternately, this is a great tool for maintaining a consistent orientation if you are delivering a bubble view (TruView, NetView, etc.) to your client. The default is to open each page oriented toward the “0” position. By knowing what that is in the field you can keep your clients oriented in the same direction or on a particular point of focus.
All in all I was quite impressed with the 5010C. While it is not a “low dough” option that some may insist upon, it is priced under other scanners that are its direct competitors (per tech specs). Add to this the fact that it comes bundled with the LaserControl processing software and I think the pricing is spot on.

From Professional Surveyor

By Sam Billingsley, PLS

Hardware and software purchases are two of the largest expenses, outside of personnel, for surveying professionals. There was a time when a surveyor could purchase a high-quality instrument and expect to use it for a decade or more. When I was first sent out to perform field surveys, I (as the new guy) got the oldest equipment. I remember turning angles with a Wild T2 theodolite that was only two years younger than me! However, those days are no more.

The dramatic advancements in efficiency and the addition of new features and technological integrations have changed the field of surveying forever. With a modern laser scanner I am collecting more points per second than I could in a year of manual surveying. I am a bit of a tech geek so I love all of these advances. However, I cannot ignore the effect that this is having on the business side of my profession.

pro-surv

This ever-increasing rate of advancement and improvement renders hardware and software purchases obsolete faster than ever before. Managing these assets in a way that ensures an achievable return on your investment (ROI) is crucial to maintaining a profitable firm.

I think we can all agree that at some point upgrading hardware and software ceases to be an option. Whether this point comes about because you can no longer afford not to upgrade or because the market demands it depends in large part on how you managed the upgrade last time around.

The goal is similar to playing the stock market. You want to hold on as long as possible to wring the most profit, but not a moment too long or you start giving that money back in lost productivity and missed opportunities. Let’s take a look at some of the variables to consider when new hardware and software purchases are on the table.

Software
Sometimes you don’t get a choice when it comes to software. If your clients demand deliverables in a particular format, you have to have the application that authors or converts to said format. However, those changes seem to occur far less frequently than the yearly updates we see in the software world. So, let’s talk about when you do have a choice.

For most major software platforms it is less expensive to stay on a maintenance package and receive automatic upgrades than to purchase them outright. This may not be the case if the software is used to produce work product and not the final deliverable, as you can typically run on older versions when work is for internal use only.

If what you’re working on is the final deliverable, it comes down to features and interoperability. Will the new feature(s) increase your profitability enough to justify the expense? Perhaps it will on one type of project but not in the aggregate. In that case you may be better off leasing the newest version for that project but waiting to upgrade the shop as a whole until next year.

Most manufacturers offer leases ranging from one week to three months long. This lease can be billed directly to a project, and it is also a good way to gauge the usefulness of a new software application prior to the purchase of a full license.

Another concern is interoperability. None of us works in a vacuum. We have a collection of hardware of varying ages from various manufacturers and processing software in the same condition. Our success is predicated on all of it continuing to talk to one another.

The place I trip up the most is in firmware upgrades to hardware. Quite often, this will have a trickle-down effect on my software. Be sure to run any considered changes through your entire workflow—field to finish—before signing on the dotted line.

Speaking of working in a vacuum, it’s a good idea to talk to your biggest clients, subcontractors, and suppliers, as well. Are they upgrading? Will their decision(s) cause a problem in your established workflow?

My last software consideration has to do with the skill set of your personnel. When it comes to survey data, the point cloud has opened up more applications to us than any one person could possibly master. The best way to secure an ROI on a piece of software is to use it to its fullest extent. The time and costs associated with training your personnel to master an application have to be factored into the cost.

Given the depth and complexity of some of these applications, specialists are popping up who just concentrate on what they do really well, be it Revit or ArcGIS or 3D Studio Max. Developing a network of these specialists can be a great way to have the best when you need it without trying to maintain tens of thousands of dollars in software that you barely know how to use.

Hardware

While total stations and GPS units typically have a lifespan of marketability that’s more than five years, I would argue that the purchaser of a new top-of-the-line terrestrial laser scanner (Leica P20, Z+F 5010C, Faro Focus X330, etc.) can expect two to three years of billable use before it is superseded by a new unit that renders it unmarketable. That doesn’t mean that it will stop working, just that you are going to have a hard time winning a project when you are basing your field costs on scanning at 50,000 points per second while your competitor is doing so at 1 million points per second.

The Apple pricing model seems to have been adopted by most of the manufacturers, so that when a new model is released it is at the same price as the previous “best” model with additional features and improvements, making it a “better” value. Added competition has reduced the prices a bit in the last two to three years, but they haven’t moved much over the past decade. For the most part, speed and compatibility are the variables here, but there are many other things to consider.
First of all, can you afford it? Given the two-to-three-year lifespan and current market rates, you are going to need at least 100 billable days per year to get your ROI.

Start by planning an ROI schedule. This is not a schedule based upon “How long will it last?” but “How long will it be marketable?” Timing is everything, so the first thing to look into is the historic release schedule of the manufacturer. While there are no hard dates, it is easy to see if a particular manufacturer typically releases a new piece of hardware every two years, four years, or whenever.

You need to know where you are in that cycle, as that will have a dramatic effect on the length of time available to achieve an ROI. If you are later in the cycle, you may need more than 100 days per year to be in the black. If you need the hardware but don’t have that type of work load, you may be better off using short-term leases or subcontracting the work to a scanning specialist.

If this is a replacement piece, check with the manufacturer or reseller to see if they are accepting trade-ins for new equipment purchases. These are rarely advertised publicly but are generally available if you stay with the same manufacturer for your upgrade.

Alternatively, you can look to the pre-owned market. You can usually find previous-generation hardware available for pennies on the dollar. However, it’s up to you to make sure it’s in good working order, so insist upon a recent calibration certificate or have it serviced by the manufacturer as part of the purchase price.

While we are looking at timelines, consider what you plan to do with the equipment when it is no longer the “latest and greatest.” Reselling it used can help recoup a bit of cash. If you need a tax break, you may do better donating it to an institution (school, law enforcement, etc.) and taking the write-off with a bit of good press.

Alternatively, we are seeing mobile scanning systems being introduced that use off-the-shelf scanners (Leica Pegasus, p3dSystems ProScan). These can be viewed as accessories that extend the usable lifespan of some scanners.

The last variable to consider is your personnel cost. Skill to do comes from doing, and you have to be honest with yourself about the non-billable hours that will be needed in order to train your personnel to effectively use any new system.

Hardware and software investments are a value proposition. The question is, “Who is receiving that value?” As such, it is important to consider any new purchase from your client’s point of view as opposed to the manufacturer’s. A tool may be smaller, lighter, faster, more accurate, etc., but the market rates for the jobs you are going to perform with it are not going to increase because you have to work less to complete them!

Your delivery times may improve. Your out-of-pocket expenses such as hotels and per diem may decrease as your field times do. You consistently get more value per dollar with your ability to perform more work in less time. But, as I said, you will still be paid the same.

The added value comes from being able to complete more projects in a given time period. Don’t forget to consider how you will fill that time in order to set aside enough profit to upgrade when the time comes around again.

Houston, TX — There are countless inaccessible places in the real world that can be brought into the digital world through 3D data capture. SmartGeoMetrics specializes in helping clients achieve this goal with top of the line hardware, robust and cutting edge software, and experienced personnel.

In 1927, the City of Houston built its first underground drinking-water reservoir at the Water Works on Sabine Street. Decades later it started to leak. The leak could not be found, let alone patched. The reservoir was drained and remained out-of-sight and largely forgotten.

In 2011 the Buffalo Bayou Partnership (BBP) took possession of the Water Works as part of Buffalo Bayou Park Development. In the course of due diligence of the property, they entered the reservoir through a small hatch and descended a single ladder into its cavernous space. What they encountered was beyond their expectations.

Light fell into the space from the entry hatch as well as two larger equipment hatches. It reflected off of six inches of water that covered the floor of the space shimmering on the walls and illuminating row after row of towering columns. Each step echoed and voices were amplified, claps of the hands reverberated for what seemed like eternity in this room large enough to hold one and a half football fields. The reservoir was dubbed, “The Cistern.”

A space like this begged to be shared. However, the logistics required to enter the Cistern are extensive and complicated: security clearances, confined spaces certification, an evacuation winch, a safety lanyard, gas monitor, hole watch, liability releases, scheduling access… How could people safely experience it?

SmartGeoMetrics (SGM) heard of the “Cistern” through a bit of water cooler talk as their offices are neighboring those of the Buffalo Bayou Partnership (BBP). SGM’s solution was to digitize the entire space as well as the surrounding features above ground. This would allow the BBP to share and promote their newly discovered assets through a myriad of digital mediums.

300 lbs of equipment was lowered through a narrow hatch down into the Cistern, High Definition Laser Targets used to Register (stitch) individual scans into one unified scan.

While making digital models of real world places has been possible for some time now, it was akin to retyping a hand written letter. The content was successfully recreated but something was often lost in the digital translation. That all changed when scanners were invented. Users could quickly scan a document and either view the original or convert it into an editable format. This same transformation is now occurring but with real world environments instead of sheets of paper. The equivalent of a JPG of a document, or the raw data format for 3D Imaging is the “Point Cloud”. Like the JPG in 2D scanning these point clouds can be viewed and give users an accurate representation of the captured environment. Point clouds can also be used to create editable formats like CAD models, meshes, or NURBS models.

The key advancements are not just the speed increases or incredible improvements in accuracy over traditional “artistic” modeling but the concept of having a single data source from which multiple computer applications can data mine. From one data collection campaign you have a perfect copy of the environment that is at the mercy of whatever applications you have! Create architectural drawings, use it as the environment for a video game or movie, make fly-through videos, print 3D models, build Building Information Models (BIM) for asset management, make VFX models, and more. Nothing exists in a vacuum, why model in one when you can design, study, manage, or create objects in the environment in which they will exist.

In 2011 the Buffalo Bayou Partnership (BBP) took possession of the Water Works as part of Buffalo Bayou Park Development. In the course of due diligence of the property, they entered the reservoir through a small hatch and descended a single ladder into its cavernous space. What they encountered was beyond their expectations.

Light fell into the space from the entry hatch as well as two larger equipment hatches. It reflected off of six inches of water that covered the floor of the space shimmering on the walls and illuminating row after row of towering columns. Each step echoed and voices were amplified, claps of the hands reverberated for what seemed like eternity in this room large enough to hold one and a half football fields. The reservoir was dubbed, “The Cistern.”

A space like this begged to be shared. However, the logistics required to enter the Cistern are extensive and complicated: security clearances, confined spaces certification, an evacuation winch, a safety lanyard, gas monitor, hole watch, liability releases, scheduling access… How could people safely experience it?

SmartGeoMetrics (SGM) heard of the “Cistern” through a bit of water cooler talk as their offices are neighboring those of the Buffalo Bayou Partnership (BBP). SGM’s solution was to digitize the entire space as well as the surrounding features above ground. This would allow the BBP to share and promote their newly discovered assets through a myriad of digital mediums.

While making digital models of real world places has been possible for some time now, it was akin to retyping a hand written letter. The content was successfully recreated but something was often lost in the digital translation. That all changed when scanners were invented. Users could quickly scan a document and either view the original or convert it into an editable format. This same transformation is now occurring but with real world environments instead of sheets of paper. The equivalent of a JPG of a document, or the raw data format for 3D Imaging is the “Point Cloud”. Like the JPG in 2D scanning these point clouds can be viewed and give users an accurate representation of the captured environment. Point clouds can also be used to create editable formats like CAD models, meshes, or NURBS models.

The key advancements are not just the speed increases or incredible improvements in accuracy over traditional “artistic” modeling but the concept of having a single data source from which multiple computer applications can data mine. From one data collection campaign you have a perfect copy of the environment that is at the mercy of whatever applications you have! Create architectural drawings, use it as the environment for a video game or movie, make fly-through videos, print 3D models, build Building Information Models (BIM) for asset management, make VFX models, and more. Nothing exists in a vacuum, why model in one when you can design, study, manage, or create objects in the environment in which they will exist.

Forrest Smith and Douglas Smith of SmartGeoMetrics stand above the site of the Cistern at Buffalo Bayou Park.

SmartGeoMetrics is known primarily for providing 3D high definition laser services to the petrochemical, civil engineering and architecture industries. The company also has a passion for providing 3D imaging of special landmarks and interesting spaces like the Texas tall ship Elissa and the Yas Marina Circuit in Abu Dhabi. Taking a keen interest in the Cistern’s size, beauty and untapped potential, SmartGeoMetrics volunteered time and resources to join Buffalo Bayou Partnership on an excursion into the Cistern in early 2012. Their goal? To acquire 3D imaging data of the cavernous space to document its as-is condition. The result?An impressive array of 3D imaging, photographs and autosteroscopic holograms which Buffalo Bayou Partnership will use in developing future plans for the Cistern, once funding is available. You can see a 3D fly-through of the Cistern here.

Buffalo Bayou Partnership is grateful to SmartGeoMetrics for providing a stunning and unique study of Buffalo Bayou Park’s hidden treasure.

GALVESTON – After nearly four months in dry dock, the official Texas tall ship Elissa is scheduled to sail back to its berth in Galveston Harbor on Saturday with a new bottom and a three-dimensional color map of the entire vessel.

A flotilla of private sailboats will escort the Elissa as it makes its way from a Texas City shipyard to Galveston Island. The Elissa is expected to arrive at about 12:30 p.m. at Galveston Harbor, where it will be greeted by a fireboat shooting an arch from its water cannon. The return will be streamed online at galvestonhistory.org.

The ship is expected to enter its refurbished berth at the Texas Seaport Museum at Pier 22 about 1 p.m. Hurricane Ike severely damaged the dock in 2008, and repairs were recently completed.

Once in port, preparations will begin for replacing its deck with 22,000 board feet of Douglas-fir, said Jamie White, museum director.

About 1,900 square feet of steel was welded to the ship’s iron bottom, White said. About 65 percent of the ship’s original iron hull and superstructure remain, he said.

The entire project is expected to cost about $1.5 million, nearly all it of from federal disaster funds, White said.

The U.S. Coast Guard yanked the sailing rights of the 1877 barque following an inspection in January 2011 that found the iron plates on its hull were nearly eaten through in places. The unusually rapid deterioration was traced to an electric cable torn loose by Hurricane Ike that speeded up a natural process called electrolysis, which eats away at the iron.

As the Elissa prepared to leave dry dock Thursday, two crews from Houston-based SmartGeoMetrics used laser scanners to map the hull, then began mapping the interior to create a 3D image that will provide a detailed historical record of the ship.

“The laser scanning will pick up very minute pieces of information, allowing you to see things that are not visible to the human eye,” said Douglas Smith, SmartGeoMetrics vice president.

First of its kind

White said the Elissa is the first seaworthy historical vessel to undergo laser scanning, a technique developed for use on the Battleship Texas at the San Jacinto Battleground State Historic Site in La Porte. The Texas was scanned in 2011, and some of the scans have been used to produce educational videos like one showing how the ship’s steam engine works.

“The scanning and the ability to put it out digitally and send it around the world enables people to see and appreciate the ship without coming here,” said Andy Smith, Battleship Texas ship manager.

A team experienced in laser scanning from the Battleship Texas assisted with the scan of the Elissa, he said.

‘Akin to 3D printing’

After developing the technique on the Texas, SmartGeoMetrics used it to map the USS Missouri and the USS Constellation while they were in dry dock. The company is donating its time and equipment for a job that otherwise would cost about $10,000, Douglas Smith said.

“The 3D imaging process is akin to 3D printing,” said Richard Lasater, SmartGeoMetrics president. “3D printing is how you get a computer object into the real world,” he said. “Ours is the opposite, taking a 3D object and putting it into the computer.”

White said the images will give him an accurate record of the hull shape that will detect any aging problems in the future.

“It’s even going to record the paint drips on the hull,” he said, marveling at the ability to capture detail. In addition, the images might be used to provide a virtual tour of the ship to wheelchair-bound museum visitors, White said. He also plans to integrate the images into the museum’s film presentation on the Elissa.

“It’s almost like you can pick up the ship like a model and move it anywhere you want it,” White said.

The Elissa museum will be open without charge at 3 p.m. Saturday, but the ship will not be ready for visitors to board until regular museum hours Monday, White said.
