Raw, static imagery from basic cameras is the usual format for prosecutors’ presentation of evidence in the courtroom. Maine State Police’s Evidence Response Team and the Missouri Highway Patrol Major Crash Investigation Unit’s innovative approach using ground scanners, drones, and photogrammetry software enables digitized workflow comprising interior and exterior scans documenting a “play-by-play” reconstruction or scene walkthrough with 4K/60 video recordings and still shots with <1 millimeter accuracy. The digitization experience offers demonstrable evidence for the courtroom, such as measurements of tire marks and proximity in evidence. Key to adoption is prosecutors’ ability to provide insight into how the coupled technologies function.
