On June 14-15, I joined Don Comstock, deputy coroner, Park County, Colorado and his team to document a mass fatality simulation staged on the outskirts of Fairplay, Colorado. At 2966 m (10,000 ft.) the air is a little thinner than sea level in Boston. The DT Research tablet equipped with the Intel RealSense D415 depth camera and Hemisphere dual frequency GNNS sensor worked without a hitch but the operator, me, felt the altitude.

​The scene simulated a bus rolling over the embankment with more than 20 passengers.  Inflatable dummies can be seen outside the bus and there were some inside as well.

More than 75 first responders from nearby municipalities joined the event.  While processing some data, I also got a rare view of the action back at headquarters where the response coordination took place. Most of us have no idea about all the effort and coordination required to respond to a catastrophe – every detail from contacting next-of-kin to managing the press to documenting the site to making sure first responders themselves are looked after. 

We captured the most the scene in full 3D with the DT Research tablet. The mobility of the tablet allowed the capture of geo-referenced data inside and outside the bus in just a few minutes.  Geo-located high resolutions image were also captured – see Figure 4.  

Annotations and measurements of the scene were also taken. See Figures 5 and 6.

This past December we were glad to continue our support for the IAFSM at their annual conference in Fort Worth, TX. To kick off the event, we were invited to participate in a very unique project: "Active Shooter: Documenting the Aftermath", a scenario-based, multi-disciplinary 3D scanning workshop off site at the Fort Worth Police Bob Bolen Public Safety Complex. This highly impressive facility is one of the top public safety training centers in the country, and provided us with the opportunity to put our very latest technologies to the test. Under the simulated scenario of a multi-agency response to a large scale active shooter scene, we were tasked to collaborate with a wide variety of law enforcement personnel, crime scene investigators, manufacturers, and different 3D capture hardware and software platforms.

While several groups split off to capture larger scale data sets with tripod scanners, mobile mapping systems, and drones, we were specifically tasked with capturing detailed, full-color data sets of some of the more crucial areas of the crime scene. The first area assigned included the gas pumps and surrounding evidence at a gas station. We scanned this area in its entirety with the new DPI-8S handheld 3D scanning kit in a matter of minutes. As best practice, we referenced two scale measurements with a laser disto, and included AprilTags for loop closure throughout the scene. The resulting data stitched together incredibly well with the larger tripod data sets and was presented as such at the end of the conference. Please see below for the .DP scan data, as well as some images from the session:

Next, we moved into the convenience store of the gas station, where a clerk had been shot behind the counter, and further pieces of evidence needed to be documented. Similarly, we took a couple quick scale measurements as best practice, and also added some AprilTags for loop closure. Please see below for the resulting data in DP format and images from the scan:

Lastly, while the DPI-8S performed especially well for these interior capture scenarios at the tactical training village, we also saw the opportunity to put the Intel RealSense D415 to the test for capturing a vehicle outside in the very bright Texas sunlight. This sensor was attached to a Microsoft Surface Go tablet, equipped with Dot3D Pro. While shiny metals can still be a bit challenging on sunny days, the RealSense did perform impressively well on the vehicle, despite the fact that it was noon on a cloudless day in the middle of the driving track at the training facility. Please see below for the resulting data and some images from the scanning session:

We would like to thank the IAFSM, Fort Worth Police Department, and all others involved for putting this excellent event together, and we look forward to more events like this in the future.

Mining has been an excellent application for our handheld 3D scanning technology since its inception. As truly portable solutions, the DPI-8X and DPI-8X SR can be easily deployed to areas inaccessible with other technologies, and fit nicely into the world of mining for 3D documentation, analysis, and accident reconstruction. Please see below for some excellent images of handheld 3D capture in dark, congested mining environments. These photos were captured in South Africa with a team from Wits University and HORTS Geo-Solutions.

However, in our latest test work in this field, we are now outside of tight underground spaces, and instead testing the capabilities for 3D documentation, distance measurement, volume measurement, and analysis of mining core. We have partnered with Imago in this testing:

"Imago is a platform to extract knowledge from geoscientific imagery. It consolidates images from any source, transforms them into meaningful insights and then connects them to the appropriate geological or mining activity. It is part of a new generation of digital solutions for modern mining."

Please see below for a video from their experiments with our technology:

And here for a sample scan shown in Sketchfab:

It's always great to see different uses for our tech being put to the test. Stay tuned for more from Imago. For more info on their technology and applications, please visit www.imago.live.

SketchUp is a powerful and user-friendly software solution for 3D design projects, from home renovation to industrial design and more. While we may not be able to import DotProduct point cloud data directly into SketchUp today, we have developed three powerful partner workflows for getting DotProduct data into SketchUp. Each has its own unique pluses and minuses. Please see below for more information and videos on each of these workflows:

1. InfiPoints DP - Import CAD surfaces and cylinders in IGES format:

This video shows the process of bringing DP data into SketchUp as CAD surfaces/cylinders via InfiPoints DP (Android) and SimLab IGES Importer for SketchUp (Windows/Mac).

2. Pointfuse for DP - Import full color 3D meshes in SKP format:

This video shows the process of converting .DP point cloud data to .SKP mesh files in Pointfuse for DP. SKP is a native SketchUp file format that will open directly in SketchUp.

3. Undet for SketchUp - Import color point cloud data via the Undet plugin:

This video demonstrates the full workflow to bring DotProduct point cloud data into SketchUp via the Undet for SketchUp plugin. Undet will read .DP point cloud files directly. Please stay tuned for more on this workflow and the process of modeling from DP data in SketchUp.

We got spooky with the DPI-8X this past Halloween at the IAFSM's 4th Annual Educational Conference in Atlanta, GA! That afternoon, we took a field trip offsite for a live scanning workshop with the DPI-8X, DPI-8X SR, and a wide variety of terrestrial and airborne 3D scanners. This was a great opportunity to demonstrate the benefits of rapid handheld capture for small to medium sized areas. Both the DPI-8X and DPI-8X SR performed very well on site, with the latter providing the highest level of detail and also slightly better results in daylight.

We were faced with a sunny Atlanta day without a cloud in sky, which of course creates significant challenges for handheld 3D scanning. However, we were glad to see a very practical approach taken for one of the grave sites. A simple tailgate-style popup tent shielded the grave from direct sunlight, allowing for excellent data capture in all conditions. While the additional graves could not initially be captured in sunlight, we waited about an hour until the sun dipped just below the treeline and were able to capture them all successfully in that afternoon. Shade and afternoon/evening scanning are two of the best methods to avoid the sunlight limitations of the DPI-8X/DPI-8X SR. Mornings or cloudy days also do the trick.

The resulting data is shown in the images above and in the presentation below. Despite the sunlight challenges, we found the results of handheld scanning were well worth the effort. While speed of capture and convenient form factor were obvious benefits in this scenario, the quality and color detail of the results were also among the best obtained. This was due to the unique ability to move in close to the body from various angles, especially with the DPI-8X SR, which allows for the closest range of capture and thus the densest results.

We would like to thank the IAFSM for involving us in this project and look forward to similar scanning sessions at future conferences. Please click below to download the DP data for viewing in Dot3D Edit, CloudCompare, and other programs. Click here to download Dot3D Edit.

The MIT Department of Civil and Environmental Engineering (CEE) deployed the DPI-8X handheld 3D scanner in Italy this summer as part of the Materials in Art, Architecture and Archaeology (ONE-MA3) curriculum. The video above provides an excellent overview of the many projects covered on the trip, with footage of the DPI-8X highlighted in the first minute.

On site at the archaeological ruins in Priverno, students used the DPI-8X to document interior architectural details of ancient Roman thermal baths, capturing degrading structures in high resolution full color 3D detail to be combined with larger scale aerial drone footage of the site. Please see below for some of the point cloud data, both from the drones and DPI-8X:

Using the DPI-8X, students were able to document the interior structures of these Roman thermal baths in full color 3D, including impressive stone arches that have stood the test of time. Analyzing this data can shed light onto the design decisions made centuries ago that have held these rooms together over all the years. Please see below for some images of the capture session and resulting data, shown in Dot3D Edit:

Back in the museum, students also took the opportunity to scan a mosaic that had been excavated and restored from the dig site for display. Combining technologies and concepts, the idea behind this project was to create an accurate digital representation of the preserved mosaic that could be viewed back in the original archaeological location using augmented reality technology. AR could very well be the future of museum experiences and handheld 3D scan data can readily bring real-world color content into this platform. Please see below for several more images from the project, including the resulting data of the mosaic:

Additional scanning projects from the trip included 3D capture of a sarcophagus in a restoration workshop, scanning of stone sculptures in a museum, and documentation of other structurally and historically relevant sites. Below are some great images of those sessions:

We are glad to partner with MIT on such exciting coursework. The overlap of various disciplines is especially relevant to the DPI-8X and its many applications. From structural engineering to archaeology and heritage preservation, the ONE-MA3 curriculum encompasses a great mix of use cases for handheld 3D data capture. I look forward to seeing further exploration of these technologies and overlapping applications from MIT in the future.
