摘要
研究非量测CCD数码相机应用于航空摄影测量的技术方法。采用基于自检校光束法平差严格标定非量测CCD数码相机;提出基于相对定向、三视张量、自由光束法平差、区域网光束法平差的空中三角测量流程。实验表明,严格标定的数码相机,可以应用于大比例尺航空摄影测量。
This paper studies the technical method of the application of digital non - metric CCD camera in large scale aerial photogrammetry. The non-metric CCD camera is first calibrated by means of self- calibration bundle adjustment. Moreover,the automatic aerial triangulation process is proposed based on relative orientation ,trifocal tensor,free net bundle adjustment as well as block bundle adjustment, Experimental results show that the calibrated non - metric CCD camera can be suitble for aerial photogrammetric applications.
