Abstract

Abstract: According to the position structure of the multi-lens cameras in the tilting aerial camera, the relationship between the corresponding coverage area of the oblique image, course, lateral overlap degree and flight speed, exposure interval time, route interval and other parameters is analyzed. On this basis, a formula for calculating the overlap degree of images taken by cameras at any number, any angle and any position is derived. The result proves that this method improves the accuracy of setting parameters of tilt photography and provides a necessary basis for the quality assurance of the later process.

Key words: oblique photogrammetry, course overlap, lateral overlap, aerial photography parameters
