Space photogrammetry of space photography

Using space photographic images and related data, through image processing, photogrammetry, topographic mapping, ground object interpretation, analytical calculation and so on. , to determine the coordinates of ground (or other planets) points and drawing work. Space photogrammetry system generally consists of measuring camera, starry camera, quartz clock and altimeter. In order to realize the synchronous photography of the starry sky and the ground. The main information and data used in space photogrammetry include not only the information and data provided by space photography, but also the coordinate measurement values of satellite and ground photos and their image points, the geodetic coordinates of ground control points and related ground measurement data.
