Collision Reconstruction and Forensics
Clear roads faster with efficient and accurate drone-based data collection and reconstruction. Ensure personnel safety and digitize your forensics process.
Painpoints
Advantages
There is an increased risk for forensic personnel when performing manual reconstruction.
Collect data from a safe distance without compromising data quality or exposing personnel to unnecessary risk.
Traffic is significantly impacted by the long reconstruction times and delays in road clearing.
Significantly reduce collection times, restoring normal traffic flow more quickly and minimizing the impact on transportation.
Inadequate data collection and a lack of realistic visual representation can add complexity to legal cases.
Capture realistic reconstruction models of the scene, which can be later used throughout the legal process.

Workflow
- Mission Planning:
- Plan Mapping Mission based on scene reconstruction needed. - Mission Execution:
- Execute the planned mission. Complement the images with POI flights using timed photo capture.
- For night reconstructions, make sure to properly light the scene for accurate data collection. - Post Mission Documentation:
- Import collected data in DJI Terra to process the scene 3D model.
- Use DJI Modify to clean a version of the 3D model, remove any floating parts, and improve overall texture quality. Sharing with other stakeholders is also possible.
