Abstract:

Aimed at a certain earth mapping system, six outside orientation elements are determined based on the actual location and attitude of the detector, and the ground coordinates of any point in mapping image are calculated using a single photo analytic method, based on three inside orientation elements of vidicon and location of the point in the image. Finally, the longitude and latitude of the point are given by exchange. The problem of real time location determination of mapping pictures is solved.

Key words: real-time location determination, coordinates exchange, mapping image
