UAV Based Mapping

​

Using the most advanced technology in the field of accident reconstruction, we utilize unmanned aerial vehicles (UAV) that can capture measurements with near centimeter accuracy. Like never before, collision scenes and the surrounding areas can come to life in remarkably accurate 3D models. The observer can see first-hand the terrain, roadway configuration, and physical evidence at any given scene.

 

The UAV takes a series of high-resolution photographs that are geo-referenced through GPS coordinates. These UAV’s have the ability to fix their location on the Earth to the maximum degree of accuracy.  Once a scene is documented the photographs are processed in an advanced software program called Pix4D. The program creates 3D point clouds and high-resolution, aerial images with very precise longitudinal, lateral and vertical distances.   The software also allows us to remove moving vehicles leaving a diagram free of clutter.

​

The 3D point clouds and high-resolution aerial photographs offer a totally unique depiction of a collision scene. The level of detail and data generated by our UAVs and accompanying software is unparalleled. A collision scene measured by these instruments will far exceed expectations and raises the bar for the standards in the field of accident reconstruction.

 

We also utilize a Parrott UAV Quadcopter.  This equipment allows us to take overhead photographs of crashed vehicles and close up views of collision scenes including the impact area.  The Parrott UAV Quadcopter has the capability to take real-time photographs and videos of the roadway and approaches to a scene where appropriate.  This can be especially helpful in grade crossing accidents by flying the UAV at the approximate height of the vehicle driver and train engineer.
