Research on the photogrammetric simulation system for the design of large-scale gossamer inflatable antenna

摘要

Because of the flexible material, the traditional measurement technique meets the requirements difficultly, and the non-contact photogrammetry technique is appreciated. Affected by the material and the precision, the design and adjust of the large-scale gossamer inflatable antenna is a difficult problem. With high precision, photogrammetry, a non-contact measurement method, satisfies the requirement of gossamer inflatable antenna design. In order to enhance the precision of photogrammetry, multi-station network is necessary, which will also affect the reliability, efficiency and stability of the results. In this paper, the simulation system of photogrammetry for the large-scale gossamer inflatable antenna is proposed. The system will provide guidance for the profile adjustment, such as network design and optimization, profile measurement and accuracy estimation etc. It will avoid the blandness and improve the productivity and system reliability. This simulation system is applied in the design and adjustment of the gossamer inflatable antenna profile. Experimental results show its validity.
