The paper presents an algorithm to find homonymous line segments from images based on the depth face of building. TIN is formed from the object points calculated by homonymous points in stereopair, and contour lines are inserted from TIN with a given interval. With image and contour lines, the different depth faces of building can be partitioned approximately. Homonymous line segments are found in different depth faces by matching along epipolar line, the method is tested feasible. It solves the problem of line matching in the changed area of building depth face simultaneously.
