Photogrammetry uses a series of photographs to develop a three dimensional image. From these paired two dimensional images, systems have been developed to determine the third dimension.

Photogrammetry systems are used for a variety of purposes. These range from:​

• Crash scenes
• Crime scenes
• Architecture and Buildings
• Roads
• Aerial photography

Traditionally photogrammetry of crime sites in Australia has been the domain of specialist photogrammctry units within the Police Service. Emphasis is placed on obtaining and recording site details. Items include:​

• Vehicle rest positions
• Key markings and debris on roads
• Roadside furniture
• Road alignment

A new system developed in Sweden, jointly between Folksam Insurance and Chalmers University of Technology, allows photogrammetry to be conducted on vehicles to determine deformation. The system requires minimal training in both taking photographs and in their subsequent analysis.

This paper outlines the photographic procedures used and developed for an indepth crash study using such a system, to minimise on scene inspection time and maximise data collection. It outlines the advantages and disadvantages, as well as future enhancements of the system.
