- Ground-based LiDAR using FARO 3d scanners and other brands of scanners have been shown to be an accurate way to capture the geometry of accident scenes, accident vehicles and exemplar vehicles, as well as corresponding evidence from these sources such as roadway gouge marks, vehicle crush depth, and burn areas. However, ground-based scanners do require expensive and larger equipment to be brought on-site, as well as other materials that may be required depending on the scenario. New technologies, such as Apple’s mobile phone LiDAR capture, have been released recently in their newer model phones, and they offer a chance to obtain similar results but with less cumbersome and less expensive equipment. This technology embeds photos with lidar data that can then be exported into point cloud data using different applications available in the app store. This paper will investigate the accuracy of Apple mobile phone LiDAR on obtaining geometry from multiple exemplar vehicles. This mobile LiDAR data will then be compared against LiDAR captured from the same exemplar vehicles using a FARO Focus 3d scanner. Multiple applications will be chosen for the mobile phone lidar export to investigate accuracy differences between the applications. The results will be compared using the software CloudCompare.
