Research on the technology of measuring inner orientation elements of remote sensing camera without radiation calibration

摘要

During the process of calculating inner orientation elements by using original measurement data of remote sensing camera, the measurement precision is too low without radiation calibration due to the inconsistent response of each CCD pixel. Based on the simulation analysis of the optical system, the method of calculating inner orientation elements by using circulation iterative algorithm combined with error analysis theory has been presented in the paper, the systemic error processing of measurement data is done and the inner orientation elements are determined. The results show that the gross errors can be effectively excluded without radiation calibration by using this method so that the measurement data can be processed accurately, and the accurate inner orientation elements of remote sensing camera and the distortion curve consistent with the theory can be obtained finally.
