Paper Abstract

A digital close range photogrammetric method for space deployable microwave antenna is presented. The planning of multi-camera stations, 3D data connection of images of different view field and the calibration of the cameras are discussed. The procedure of calibration has two steps: direct linear transformation and the bundle adjustment. The measurement error resulted from lens distortion can be corrected. The relative accuracy of 1 part in 1000 can be achieved using on site automatic calibration during measurement. The profile of the space deployable microwave antenna was obtained through the least squares fitting of the adjusted observations.
