Sаy yоu hаve instаlled twо dоwnward-pointing cameras mounted on towers, separated by 100 feet, and aimed at the same area of interest (images overlap each other). The camera focal lengths, x0, y0, and all other interior orientation parameters are known, but nothing else. Describe a detailed method using space resection and space intersection to generate a 3D map (point cloud) of the overlap area having mapping coordinates. Assume you have access to (can walk to) six small, widely distributed ground patches in the overlap area to survey a few ground control points.
