Paper Abstract

A point matching method in photogrammetry for microwave antenna with non-metric cameras is presented. The method with coded points and epipolar constrain is described. To solve the point matching in large measurement range, the idea of the dividing area is presented. The circular coded points as identifiers are used to identify different subareas, and subarea matching is preformed. Then, the measured points are matched with epipolar constraint in each subarea of left and right images. In order to reduce the influence of lens distortion to epipolar constraint, a control points grid as frame of reference is used to correct all image points using a distortion model. Experimental result indicates that this method is valid and reliable to reduce data processing time, and to improve image matching veracity and automatic degree. The points matching ratio is 100%. This method has provided one excellent solution for point matching problem in large object photogrammetry with non-metric cameras.
