| Abstract: | 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. |

| Keywords: | camera calibration photogrammetry bundle adjustment relative orientation |
