Abstract
The deformation measurement and monitoring of large-scale antenna is very important for antenna users as well as manufacturers. This paper proposed a large antenna measuring method based on total station and vision guidance. Firstly, an automatic measuring model was established based on photogrammetry, precise distance measuring and angle measuring technology which used a camera to recognize the key points on the antenna and guide the total station to automatically aim at them and accomplish measurement. Then research was emphatically focused on automatic object recognition, calibration of spatial relationship between the camera and total station. Also collimation errors were compensated to improve the measuring accuracy. Finally experiments were carried out and the results indicated that the measuring error of the system could be within ±1mm in the measuring range of 60m which can meet the need of large antenna measuring demands in certain projects.
