Notes:
The inflatable space antenna is gradually used in various spacecrafts because it is portableand foldaway. It is usually made of thin-film materials and has a flexible surface, so that measuringforce is not tolerable in measurement process. Close-range photogrammetry is considered as anoptimal solution because of its advantages of non-contact operation and fast data acquisition. Toimprove measuring precision, a method combining bundle adjustment algorithm and the distanceconstraint is presented in the paper. Two experiments under different conditions are accomplishedand experiment results are compared. One experiment is completed with the distance constraint andanother without. The experiment results are compared by two parameters: tightness and residuals. Themeasured object is an inflatable antenna with a 3.5-m diameter
