Simulation of Geometric Measurement Method for Stereo Mapping Camera

The imaging accuracy of data-transmitted satellite photogrammetry based on stereo mapping is determined by the accuracy and stability of measurement for interior orientation elements. The methods of measurement for interior orientation elements must be studied specially. The methods for measuring geometric accuracy of data-transmitted stereo mapping camera are proposed. Based on the least square algorithm for geometric measurement, the formula for error propagation of principle point, principle focal length and distortion are obtained. The simulated analysis for measuring accuracy of principle point,principle focal length and distortion are achieved and the results can offer a reference to designer.
