Photogrammetry technology has been gradually applied in the development of large satellite antenna, and the experimental evaluation method for deformation measurement of large satellite antenna proposed in this paper is derived from the development task of large flexible antenna, which needs to conduct reflector measurement in a vacuum and cryogenic environment based on the principle of photogrammetry.Therefore, it is necessary to establish an evaluation method for large satellite antenna deformation measurement based on photogrammetry.The repeatability and accuracy of the measurement results can be judged by the method.In this paper, a method of measuring repeatability and measuring accuracy is proposed, and the measurement results are evaluated by defining the concepts of single point measuring evaluation factor and length measuring evaluation factor.This evaluation method has been successfully applied to the measurement of large antenna deformation in vacuum and cryogenic environment.
