| Abstract: | For liner-array sensors on spatial platform, based on the analysis of sensor distortion, pixel size zooming, focal length zooming and sensor rotation, a self-calibration model with eight interior calibration parameters is constructed. Based on orientation image interpolation model, and the movement of exterior parameters, a self-calibration bundle block adjustment model is provided, in which the process of model linearization, exterior calibration parameters of orientation images are introduced. Based on SPOT5 simu- lation data, experiments have been done on the block adjustment model, which proves that the model will simultaneously and precisely calibrate interior self-calibration parameters and orientation image exterior pa- rameters. |
