An Automatic Precise Registration Method Based on the Relative Geometric Calibration Between Bands for Satellite Multi-spectral Image

A registration method for satellite multi-spectral image is proposed, which is based on the relative geometric calibration between bands. This method precisely calibrate the relative geometric distortion of reference and non- reference band, and ensure that the exact geometric imaging models of different band images have great relative geometric accuracy. Based on the exact geometric imaging model and the same-name pixels positioning consistency, the exact same-name pixels conversion relationship of reference band and non-reference band can be obtained, which can guarantee that the accurate automatic multi-spectral image registration can be realized without image matching. This method is a real geometrically registration, and the correction model between bands is exact geometric imaging model. It is theoretically rigorous, and the registration result couldn’t be affected by the image quality. In order to verify the correctness and feasibility of this method, the experiment has been carried out on ZY-3 satellite multi-spectral image. By now, this method has been successfully applied in the satellite images pre-treatment process.
