New film-based motion analysis system characterized by a data-matrix readout subsystem using CCD image processing

A new motion analysis system has been developed for the data readout of the film obtained from the applications of high speed photography. The system is composed of a step-motor driven high accuracy film transportation part, a data matrix readout subsystem employing CCD image processing technique, a high accuracy transparent electromagnetic digitizer, and a microcomputer with all the software package of data reading, image catching and processing, and object movement analyzing included. Depending on the new technique used in it, this motion analysis system can carry out fully automatic readout of data matrix with high accuracy and versatility, even though the image of data-matrix on the film is not clear.
