Abstract:
This paper discusses the displacement measurement of antennas by means of digital close range photogrammetry. Two convergent CCD cameras are used to obtain pictures of the measured surfaces, the images’ central coordinates of special targets on the surfaces are deduced, and then the central coordinates of the targets are calculated by the bundle method. The accuracy may reach 1:20000, and the method can be applied in satellite antennas’ test under space simulation conditions before launch, to ensure antennas’ reliable work.
