Paper Abstract

Techniques of digital close-range photogrammetry were successfully used in the high-low temperature deformation measurement of satellite antenna's reflector in thremal vacuum in this paper, and problems of traditional measuring methods that can not be conducted in the vacuum environment were overcame. Excitingly, the measuring precision of the new method with two 8-megapixel digital cameras contained in custom-made pressurized canisters could reach 0.1mm, and could satisfy the designing requirements of products.
