摘　　要：本文研究了无人机航空非量测数码相机常见的精度检校方法,以及数码相机自检校常用的几款软件,设计了一套基于光束法平差的自检校方案。通过分析不同软件的自检校结果,对空三加密和立体模型定向精度进行对比,验证了基于地面检校场自检校精度的可靠性。对低空无人机摄影测量的相机检校有一定的借鉴意义。This paper studies the common checking methods of non-metric digital camera and some software of digital camera self-calibration,and designs a checking scheme based on bundle adjustment.The self-calibration results from different software are analyzed,and the accuracy of aerial triangulation and stereo model orientation is compared,which proves the reliability of self-calibration accuracy based on ground inspection.The contents of this paper has reference value for the camera calibration of low-altitude UAV photogrammetry.
