Abstract

The photogrammetric system in vacuum cryogenic environment is designed to measure the sharp deformation of the satellite antenna due to the thermal deformation. The method of the measurement is based on the close-range photogrammetric techniques. This system includes CCD photography assembly, scale bars, support structures and the software. A test was performed by using this system, and the sharp deformation of a reflecting antenna was measured. In the test, a plenty of data was acquired, then the measurement method was proved feasible. According to analysis, we can acquire that the relatively measurement precision by this system can reach to 1:20000.
