| Abstract: | This paper introduces a large antenna by the high accuracy digital photogrammetry technology based on a high accuracy special digital camera.The retro-reflective targets are made of special materials.The orientation of all camera stations is realized automatically and the homologous points are matched by the coded targets.The unknown point coordinates are calculated by the bundle method.The positional accuracy achieves 0.11 mm,and the surface fitting accuracy achieves 0.4 mm.It justifies the results by comparing the above results with total station instrument results. |
