The object of this paper is offer an analytical method for solving the very important stereo-bridging problem in photogrammetry. In solving this problem we suppose that at the beginning and at the end of an arbitrary photo-strip there are three ground control points having their immages on the corresponding two pairs of photographs respectively. Based upon this condition we can utilize the stereo-resection method to carry out the aerial triangulation throughout the entire strip in order to get enough space...

The object of this paper is offer an analytical method for solving the very important stereo-bridging problem in photogrammetry. In solving this problem we suppose that at the beginning and at the end of an arbitrary photo-strip there are three ground control points having their immages on the corresponding two pairs of photographs respectively. Based upon this condition we can utilize the stereo-resection method to carry out the aerial triangulation throughout the entire strip in order to get enough space intersection points for each intermediate photograph possibly to be mapped by virtue of some simple instruments.This paper is the extension of a previous article entitled "Photogrammetric Space Resection", published in the Chinese Journal of Civil Engineering, Vol. 1, No. 4, Dec., 1954. At present, as the writer has not get gone so far into numerical computation, how would this method be workable is subject to test in the near future. The prospect of not only furthering the theoretical foundation of photogrammetry but also opening a new approach to the photomapping problem is highly encouraging.

Based upon the correlation analysis of coefficient matrix of a space resection problem, a new space resection method and a methematical model are given. The posteriori weights of observations are then estimated to improve the accuracy of adjusted results. Finally, the correctness of this method and model is verified through data processing with a computer.

In observing displacement of a high Pressure intake conduit for a hydroelectric station, the resection method is adopted to measure the displacement of the concrete mound for fixing a 1.5 meter long steel tube filled with water. The method of calculating displacement with angular difference from two times of observing gives satisfactory results. The result of computation shows that the error of observation Point is within 0.045mm. In comparison with other observation method, this one is more convenient and precise. So it is a better method for the observation of structural displacement.
