Paper Abstract

Analysis of motion is an important aspect of automotive safety crash testing. As in other applications, high speed photography is frequeutly the best way to obtain motion analysis, and it is usually important to now the accuracy of the motion data that is obtained. In any high speed film analysis system there can be many sources of data error. Generally, error results from either optical distortion, and resolution limits or from limitations in the setup of the test being photographed. Methods of analysis for error of this latter type, such as parallax error, are quite dependent on the specifics of a given test setup and are not discussed in this paper. Techniques for analysis of distortion and resolution error can be quite universal. The following is intended to provide techniques for quantifying in a useable fashion, the error from distortion and resolution limits.
