High Speed Image Analysis: A multi parametric study affecting measurements in controlled impact tests

The field of Passive Safety is of primary focus for the automobile manufacturers. Number of changes has been incorporated in today’s passenger car, which not only protects its occupants but also other road users. This revolutionary change in technology calls for new development in evaluation procedures. Crash testing of vehicles is one such massive field of research. The nature and cost of these tests increases the need for better measurement techniques. High speed cameras are often used in the crash tests and image processing is done to study the deformation characteristics, dummy kinematics and steering wheel displacements. This paper discusses the effect of key factors like Camera positioning and 2D Calibration on the analysis of high speed images. The paper also discusses the experimental evaluation carried out to validate the same.
