The Results of Measurement by Stereo Comparator (Stecometer)

Abstract

This paper is prepared to report and confirm the results obtained by Stecometer, because it is considered that the analytical triangulation is on the rail and the stecometer results became in concrete.Using this stecometer since June 1966, although we were sufferred by mechanical troubles, we have observed 4, 360 models consisting of 2, 930 wide angle models and 1, 430 normal angle models by the end of February 1967.The statistical observation was made on the maximum residual parallax standard deviation and its closure in relative orientation, and the vertical difference (delta Z) of pass points on adjoining models.The models used for this purpose are 800 models of wide angle pictures excluding 20 models mistaken out of 4, 360 models above. The normal angle pictures were excluded in this study because of limited models available on hand.We also added in this report the detail and frequency of mechanical troubles.We shall be appreciated if the authorized people concern would advise us the maintenance of this stecometer which has many mechanical troubles for users.We would like to review on normal angle pictures at the next time concerning to the results of relative orientation or topographical features such as mountaineous area and plain area.
