Bundle adjustment has been evaluated as the best methodology in aerial triagulation from the theoretical point of view. Research works on bundle adjustment have been done mainly in Europe and America, though research and development on bundle adjustment has not been done but strongly requested in Japan. Fortunately Murai Laboratory, Institute of Industrial Science, University of Tokyo has succeeded in developing a computer program on bundle adjustment in cooperation with Teikoku Survey Co., Ltd. In this paper the results obtained from the experiments will be presented. The experiments involve the comparisons of accuracy between conventional polynomials method and bundle adjustment for 23 photographs of three courses. Comparative study was done between the three cases with respect to number of control points and between without self calibration and with self calibration. From the results of the study, it was made clear that bundle adjustment always gave the better accuracy even in the case of less number of control points as compared with conventional polynomials.
