Evaluation of Consumer Grade Unmanned Aircraft Systems for Photogrammetric Crash Scene Documentation

The use of consumer-grade unmanned aircraft systems can decrease incident clearance times and provide high quality ortho-rectified images. This paper presents a field procedure for preparing a crash scene for a UAS mission and mission design parameters. Two missions were flown at an altitude of 20 m and were completed within flight times of 6.9 minutes and 12.0 minutes. Subsequent analysis of the imagery found that the ortho-rectified imagery produced by the consumer-grade UAS had a maximum observed error of 2.3 cm. In addition to the ortho-rectified imagery, physical 3D prints can be made in under 1 hour with low-cost 3D printers. Based upon the speed of the field work, short flight time, and high-quality scaling accuracy, there is an opportunity to significantly reduce incident clearance times by training public safety officials to deploy UAS for crash scene mapping. Not only will the resulting imagery provide improved graphics, but additional secondary crashes can be prevented by reducing the duration of the road restrictions and queueing.
