This report covers an experimental trial whose aim was to establish if photogrammetry is, in general, a more accurate method for obtaining crush measurements than the conventional manual method. Photogrammetry has been used widely in the USA as a means of deriving a number of dimensions which were not measured at the scene or elsewhere. For some unknown reason it has not been adopted more widely within Europe and the UK. The use of photogrammetry, and in particular the PhotoModeler product, has proved to be of use in crash investigations where the vehicles are no longer available for inspection. It is a tool that offers the investigator a means of determining values of crush, to calculate collision severity where this cannot be derived from other physical approaches. |
