The purpose of this study was to establish the automated VTR motion analysis system by Two Dimensional Direct Linear Transformation Method. Video digitizer equipped with video cassette recorder, personal computer were used for the VTR film analysis, where the coordinates were automatically transferred into the computer. The position data calculated by 2D-DLT method were very accurate. The mean deviations of computed coordinates from the actual coordinates were 0.012m in the horizontal direction (x), and 0.013m in the vertical direction (y).
