Difference between close-range photogrammetry and ordinary photogrammetry
The difference between close-range photogrammetry and ordinary photogrammetry lies in their different purposes. According to relevant data, the main purpose of ordinary photogrammetry is to obtain topographic map, and the spatial coordinates corresponding to image pixels must be obtained. The main purpose of close-range photogrammetry is to determine the external shape, size and motion state of the target, and generally obtain the relative spatial position without paying attention to the absolute position of the target point.
