Direct linear transformation (DLT) method was applied to the three dimensional anthropometry using slide film image, and the limitation of estimation accuracy was examined by comparing values obtained through the computation based on DLT procedures and manual measurement. The standard errors of estimated three dimensional coordinates were around 4mm in 1, 000mm×1, 000 mm×2, 000mm of calibration area. Also, the acceptable estimation errors of anthropometric dimensions were obtained through the present photogrammetry. The three dimensional slide film analysis with DLT method thus may be an useful photogrammetry for estimating anthropometric dimensions as well as spatial relations among anthropometric landmarks.
