The use of terrestrial laser scanners has revolutionized the forensics investigator’s ability to capture evidence data at crash and crime scenes by significantly reducing the man hours required, while simultaneously improving accuracy of the measurements. This white paper is the result of an experiment and demonstration performed by Dynamic Safety, LLC, with the use of the FARO® Focus Laser Scanner, to establish and report best practices in scene marking, scanner placement and scanner settings to yield the most ideal results for crash and crime scene investigators.
