The purpose of this study was to establish the automated 16mm motion analysis system for three dimensional cinematography(DLT method).Nac motion analyser equipped with graf-pen degitizer,and NEC personalcomputer were used for the 16mm film analysis,where the coordinates were automatically transferred into the computer.The position data calculated by DLT method were very accurate.The mean deviations of computed coordinates from the actualcoordinates were 0.011m in the vertical direction(Z),0.019m in the horizontal direction(X)and 0.008m in the horizontal direction(Y).
