Photogrammetry Practice for the First time of LMCCD Camera Imagery

Abstract

Abstract:

The LMCCD camera is one of the payload in TH-1 satellite,which is the key step to ensure photogrammetry accuracy without ground control point.The camera parameters of TH-1 is calibrated on-orbit using LMCCD imagery and three-line-array CCD imagery, and the position accuracy are statisticed using different on-orbit calibration results especially the elevation error. The experimental results shows:The adjustment strip system deformation caused by satellite attitude change rate can be resisted in camera on-orbit calibration using LMCCD imagery compared with the single three-line-array CCD imagery.Under condition of the satellite attitude change rate in TH-1,it can be ensure o1 star of TH-1 photogrammetry accuracy without ground control point with camera parameters on-orbit calibration using LMCCD imagery.

Key words: satellite photogrammetry, three-line array CCD imagery, LMCCD camera, aerial triangulation
