Handheld 3D Scanning with the DPI-8X SR for Modern Mining Geoscience

6/28/2018

0 Comments

 
Chris Ahern, Marketing Manager - DotProduct Boston

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:

4/22/2018

0 Comments

 
Chris Ahern, Marketing Manager - DotProduct Boston
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.

Scanning Clandestine Graves with the DPI-8X Handheld 3d scanner at the IAFSM 2017 Conference

12/13/2017

0 Comments

 
Chris Ahern, Marketing Manager - DotProduct Boston
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.

DPI-8X at MIT: Exploring Ancient Engineering to Inform the Future

10/26/2017

Chris Ahern, Marketing Manager - DotProduct Boston
​
Materials in Art, Archaeology and Architecture program takes students to Italy for unique fieldwork experience with the DotProduct DPI-8X.
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.

Scanning a Mississippi Pushboat - 3X faster with the DPI-8X

7/12/2017

0 Comments

 
Tom Greaves, Chief Marketing Officer - DotProduct Boston

Last month I traveled to Florida Marine Transportation’s (FMT) shipyard just outside of New Orleans. Ship Architect’s Josh Trippi arranged for us to visit a new 120 foot pushboat under construction so we could capture the grating geometry prior to installation of deck material.  FMT has a contract to build five of these workboats and the goal is to make them all the same.
Trippi’s team had been onsite three weeks prior and had measured the grating geometry  by hand using tape measures, plumb bobs and making sketches in a notebook so we had a good baseline to compare our handheld scanning against.
 
It was hot down in the belly of the boat; water was dripping everywhere and we endured a few dust clouds when some ventilation pumps started. My 30 year old Redwings which first served me on oil rigs in Oman and Abu Dhabi were just right to keep from slipping on the steel framework.
 
It took us about an hour to set up four survey targets and scan the area of interest.  I used a Leica S910 disto to survey in the checkerboard target coordinates and then scanned the scene with our DPI-8X.  The disto is a nice-to-have, not must-have but it does allow us to wring out scale and drift errors in the handheld data.  We have a good workflow to use the control points we capture with the S910 or other disto’s as constraints in a post processing optimization step.
We got some excellent data which we subsequently registered with the Ship Constructor model which had been created from the measurements previously collected by hand.  We got the data into ship coordinates by picking a common point and then using a bulkhead plane and level section of a stringer on both the CAD model and the point cloud.  We exported the registered data sets to the Bloom Cloud Engine.
Measuring and documenting by hand allowed approximately 50.5 square feet/hour/person.  We estimated capturing the data with the DPI-8X allowed approximately 136 square feet /hour/person; a whopping 270% improvement.  We have yet to compare the modeling times with each method but we expect additional improvements because the scan data is digital and does not need to be entered by hand. Other advantages that we see include reducing the likelihood of having to make repeat visits to capture missing data – scan data is typically very complete as well as better visualization.

Automatic Accuracy: Getting the most out of DotProduct Data with the Accuscale-DP Scale Bar Kit

6/7/2017

0 Comments

 
Chris Ahern, Marketing Manager - DotProduct Boston

​The DotProduct DPI-8X is a highly accurate standalone 3D scanner. However, for larger scan jobs and/or jobs with the strictest tolerances, we often recommend implementing targets for the absolute best results. This helps to reduce potential drift within the scan and provides a scale verification within the data. However, this typically means a lot of additional effort before and after the scan session. Mounting targets, taking measurements, calculating control points, preparing targeting files, and post-processing the targets into the data can be a very time-consuming and laborious process for each scan. Even worse, if one measurement or control point is even slightly off, this can create results worse than if no targets had been used at all.

Enter the AccuScale-DP from Brunson Instrument Company This revolutionary scale bar kit, paired with the intelligence of Phi.3D 2.1 & up, achieves all of the benefits of scale bar targeting, without any of the challenges and risks of traditional targeting mentioned above. This scale bar targeting workflow is impressively simple:
  1. Set up the scale bars at maximum distances within your scene along each axis.
  2. Capture each target at least once during scanning (turning green, red, & blue).
  3. Specify the environment temperature in Phi.3D (with the included digital thermometer).
  4. Optimize with the target locations and exact distances automatically used a a reference.
Please see below for a full video tutorial on the workflow:
These kits come in a set of six 1-meter bars and can be assembled in any configurations from there. For example, if you are scanning a room in all three dimensions, you would likely want to set up three 2-meter bars on on each axis. However, if you are scanning a stretch of piping along a wall, you may want to set up one 2-meter bar on the z-axis and one 4-meter bar along the pipe, or maybe even one 6-meter bar for maximum distance on one axis. You have complete flexibility here, and only need to make sure each bar has the same colored targets on each end. Please see below for the full components of the kit:
Picture
While the kit can add value to almost any scan, there are certain jobs that are a perfect fit for this technology. One such application is crime scene mapping and forensic reconstruction. With a need for highly accurate data and a hard reference to scale within the scene, the AccuScale-DP is a perfect fit. In a recent webinar from the IAFSM (International Association of Forensic and Security Metrology), we see the kit put to the test for ISO 17020 Accreditation. Tested against the results of a Leica ScanStation C10 tripod laser scanner, the measurements were within 2-3 mm of each other, with both devices achieving similar accuracies of about 99.75%. Please see below for the full webinar on use of the DPI-8X and the AccuScale-DP for forensic mapping, with the validation procedure and results starting about 23 minutes in:

Working With Dotproduct data In Siemens NX via Infipoints DP and Bentley Pointools

5/16/2017

0 Comments

 
Chris Ahern, Marketing Manager - DotProduct Boston

Last week on the showroom floor at Siemens PLM Connection 2017 in Indianapolis, I found myself exploring some of the best workflows for import of DotProduct data into Siemens PLM applications, such as NX 11. These traditionally solid-based applications are widely used for product lifecycle management and design engineering, but haven't traditionally paired as well with laser scan point cloud data. While I found some simple ascii point cloud import functionality available in NX, it is very limited in terms of the number of points and is not designed for use with high density color scan data. This is also the case for many other solid-based mechanical design applications. This led me to InfiPoints DP and Bentley Pointools.

InfiPoints DP offers the most rapid and direct workflow into NX for DotProduct scan data. Operating on Android with Phi.3D and Dot3D, InfiPoints DP rapidly reads DP scan data and exports IGES or DWG solids in a matter of minutes. The application recognizes all surfaces and cylinders in the DP data and converts them into solid features during this process. All these solids can then be exported into a single IGES file, which imports directly into NX. The best part? By avoiding the point cloud data, these solid features are very lightweight and fast to work with in NX, and no additional conversion is necessary on the PC. Please see below for some images of DP data in Dot3D on Android and IGES data in Siemens NX on Windows 10, converted automatically on Android using InfiPoints DP.
While InfiPoints DP is a great workflow for many applications, it can sometimes still be beneficial to utilize the full color point cloud data as a reference, especially in more complex environments. It is for this reason that Siemens has partnered directly with Bentley Pointools. In Pointools or the free Pointools PODcreator, users can import DotProduct data in PTX, PTS, or XYZ format, and export POD point cloud files. POD data will now import directly into Siemens NX 11 as reference point cloud data. Please click here for more on what is new in NX 11 and see below for a brief video on the workflow.
With a growing list of workflows and partners, we aim to make working with DotProduct data rapid and easy in a wide variety of 3D environments. Programs like InfiPoints DP and Bentley Pointools are also helping to bridge some of the gaps.

Field Registration: DPI-8X and Z+F 5010X

4/10/2017

0 Comments

 
Chris Ahern, Marketing Manager - DotProduct Boston

How can I merge my DPI-8X data with my tripod scan data? This is one of the most common questions from DPI-8X customers, and can be accomplished in a variety of ways. 

In today's video blog, I'm excited to highlight the workflow to register DPI-8X data with tripod scan data wirelessly in the field. With the DPI-8 or DPI-8X handheld scanner, Z+F 5010X or 5016 Imager, and Z+F LaserControl Scout scanning software, users are now able to add handheld data directly into their tripod data set in the field at the time of capture. LaserControl Scout is Z+F's solution to in-field registration and remote scanner control. Operating on a Surface Pro on site, this allows DotProduct and Z+F customers to align and register handheld and tripod data, all on a touchscreen tablet in the field with no need for wired transfer or moving data on USB drives.
As shown in the video below, the DPI-8X is great for capturing hard-to-reach or occluded areas, while the 5010X is one of the best scanners on the market for accurate capture of larger areas. This video tutorial walks through the full process of leveraging both technologies in the field with LaserControl Scout. The process begins with launching the tripod scan from the tablet, continues to capturing an occluded area with the DPI-8X, and concludes with the wireless data transfer and on-tablet registration procedure. The full video is available below or here.

Of course there are other ways to register DotProduct data with tripod-captured data. Within 
Phi.3D, setting a coordinate system or implementing survey control points allows you to georeference the data right on the tablet. Outside of Phi.3D, options range from using software such as Trimble Realworks or Leica Cyclone, Gexcel 3D Reconstructor, Autodesk ReCap or Bloom CE, or open-source programs such as CloudCompare. However, all of these options require post-processing of the data on a computer.
Step 1: Large area laser scan with the Z+F 5010X (00:37)
Step 2: Scan occluded area with the DotProduct DPI-8X (01:51)
Step 3: Register the two scans together with Z+F LaserControl Scout on the tablet (04:02)
