The use of 3D technologies such as the laser scanner, photogrammetry and handheld scanners for the documentation and analysis of collision scenes are extremely powerful tools. Research in this area has shown that the accuracy and repeatability of measurements agree with or exceed traditional methods. 3D technologies allow for more complex scenes to be recorded with the added benefit of reducing documentation time. New sensors and devices continue to become available at an accessible price point which traditionally has come at the expense of accuracy. This presentation provides an update on what low cost, 3D Technologies (hardware & software) are available to assist the traffic accident investigator, and how accuracy is improving on low cost, mobile devices to provide data suitable for forensic purposes.
