High-resolution 3D laser scanning is coming soon to phones and tablets with the release of Dot3D™ 4.0 (beta) and the Intel® RealSense™ LiDAR Camera L515. When paired with Dot3D™ Pro, this revolutionary solid-state LiDAR depth camera enables 3D capture of color point cloud data with unprecedented accuracy and detail. Today we are glad to announce that all active Dot3D™ Pro customers will gain support for the Intel® RealSense™ LiDAR Camera L515 with the release of Dot3D™ 4.0 beta the week of July 26, 2020.

​
Click here to sign up for the latest L515 updates, sample data, and beta access.
L515 LiDAR
All current Dot3D Pro subscribers will gain access to this functionality as soon as it is available. This includes active subscribers, perpetual license holders with active support and maintenance contracts, and all new Dot3D Pro customers between now and the release. Please be advised that Dot3D pricing is subject to change, so we recommend locking in L515 access now with the purchase or renewal of a Dot3D Pro subscription or perpetual license before July 26, 2020, including all new DPI-10 and DPI-10SR orders.
L515 Video
The L515 offers the longest range of any depth camera supported by DotProduct to date. It is expected to be fully compatible with all DPI-10 kits, as well as all other phone/tablet kits meeting the minimum specs. While we expect the L515 to be an excellent option for indoor scanning, please note that it will not work in direct sunlight (D415 recommended) or at very close ranges (DPI-10SR recommended). DPI-10/SR kits will continue to provide the most comprehensive offering for those looking for a complete kit for all environments, with full support for the L515, D415, D435, D435i, and D455 (coming soon).

Handheld 3D Scanning Data Supports Conviction in Criminally Negligent Homicide Case

6/15/2020

Tom Greaves, Chief Marketing Officer - DotProduct LLC

On February 27, 2020, Shaypher Lee M. Hendricks was convicted of criminally negligent homicide, driving under the influence and reckless driving in connection with a single-vehicle crash on July 12
th, 2016, on Highway 18, near Milepost 3.5, north of Lincoln City, Oregon. Passenger Austin M. Mayhak (27) was found deceased in the front passenger seat of the 2016 GMC 2500 Savana cargo van. Highway 18 was closed for approximately 8 hours to clear the scene.

​Billy Bush, a District Lead Reconstructionist for Oregon State Police’s Collision Reconstruction Unit testified at Hendricks’s trial following his investigation. The defense claimed he was the passenger in the vehicle, not the driver, and therefore was not responsible for the crash or the loss of Mayhak’s life. Three years after the incident, Bush, an ACTAR accredited Reconstructionist, reopened the investigation when the defense successfully moved to exclude the admission of expert testimony from a non-accredited CRU member who had led the investigation in 2016.
 
Following Bush’s investigation, the core of the prosecution’s case was showing the vehicle dynamics, occupant kinematics, and Principle Direction of Force excluded the possibility of the passenger surviving the crash. Consequently, the survivor was ultimately determined to be the driver.
 
Bush obtained a search warrant for the vehicle, which was kept as evidence and used a DT Research DT301X-TR tablet equipped with an Intel RealSense D415 sensor and Hemisphere GNNS sensor and running DotProduct’s Dot3D Pro software to produce a 3D point cloud of the wrecked vehicle. First, four AprilTags were positioned around the vehicle and their centers were surveyed with centimeter grade accuracy using the Hemisphere dual-frequency GNSS sensor onboard the tablet running Leica Evidence Recorder software. The AprilTag coordinates were then imported to DotProduct Dot3D Pro for post-processing of the point clouds collected with Dot3D Pro using the RealSense D415 sensor. According to Bush, it would have been impossible to use a tripod laser scanner effectively for the data collection because of the proximity of nearby vehicles and obstacles in the evidence yard. Storage space is at a premium and vehicles are stacked close together.

Figure 2 -- Dot3D Point Cloud Data Captured with Intel RealSense D415 Camera (Courtesy Oregon State Police)​
​The crash reconstruction showed that the vehicle had hit a tree on the passenger side and that the tree had ripped off the passenger-side A-pillar and roof. It was also determined that the cargo partition behind the passenger had been displaced to the rear and the passenger had been caught in the path. At the trial, Bush used the Dot3D Pro software to show the jury the force lines and vehicle crush navigating in real-time to multiple points of view, including perspectives from the front of the vehicle looking back, the side of the vehicle looking in and the top of the vehicle looking down. Bush measured the deformation caused by a tree impacting the front of the vehicle matching this to the tree diameter and damage orientation. Using the point cloud data and after extensive cross-examination, Bush established for the jury that beyond a reasonable doubt, the passenger had perished in the crash.

Herein lies the power of point clouds for crash reconstruction. The reconstructionist can bring the vehicle to the jury and show it from any point of view. Often it is not practical to take the jury to the crash scene or the evidence yard and even more challenging to show jurors the evidence from the same point of view. Photographs and video presentations are necessarily limited to the point of view of the camera at the time the images are collected. Viewing the data from the top of the vehicle, for example, would not be possible with photographs unless the scene photographer had thought to photograph from that vantage point. The interpretation of point clouds can be restricted to real-world measurements, unlike animations. In this trial, while the judge excluded IIHS videos showing exemplar crashes, he admitted the Dot3D vehicle point cloud after defense objections were met with responses further establishing its scientific foundation.

Of course, the defense also has to have access to the data without the burden of having to purchase expensive proprietary software. Standard operating procedure for the Oregon State Police is to provide industry-standard outputs including PTS, LAS, LAZ and E57 files, all of which can be exported directly from Dot3D. OSP also provided the defense the DotProduct binary .dp file and link to the company’s free viewer. According to Bush, this standard operating procedure more than satisfies discovery requirements.

ACSR 2018, Tacoma Washington – Birthplace of a New Scanner
At the 2018 Association for Crime Scene Reconstruction annual meeting in Tacoma, WA, I met up with Mario Gosalvez from DT Research and Stewart Snider from Kuker-Ranken, Inc., one of the conference exhibitors. There we began a conversation about the benefits of embedding the Intel RealSense D415 camera on a ruggedized tablet together with an RTK capable GNSS sensor. The idea was to create a solution to produce georeferenced point clouds in the field.
 
We subsequently learned that OSP Reconstructionist Billy Bush had been in discussions with DT Research reseller Kuker Ranken about his research using an externally mounted Intel RealSense D415 sensor on the tablet.  From these good ideas and a short eighteen months of development, the product was born and some of the first units went to the Oregon State Police. We note that this complementary combination of technology that helped lead to the conviction of Hendricks did not exist when Hendricks committed his crimes.
 
About Oregon State Police Crash Reconstruction Unit
The Oregon State Police Collision Reconstruction Unit (OSP-CRU) is charged with the investigation of  motor vehicle crashes/collisions and documentation of evidence at crime scenes for scene reconstruction. Investigations often involve fatal or serious injury motor vehicle collisions with a criminal element, or homicide investigations.
They have specially trained investigators located throughout the State of Oregon. Their staff currently includes 14 internationally accredited Collision Reconstructionists by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR), and 32 Technical Collision Investigators. The program is directed by the Collision Reconstruction Program Manager and five District Lead Reconstructionists, all of whom are ACTAR accredited.
Their personnel receive ongoing specialized training in the field of Collision Reconstruction to establish technical excellence. The training includes heavy emphasis on evidence documentation, mathematics, and physics. They maintain training to keep pace with advancing technology (e.g. vehicle event data recorders), and continuously research the application of emerging technology. They are often called upon to provide expert testimony in the courtroom.
