| Abstract: | A method for geometrically correcting the remotely sensed satellite images is described. A simple and practical dynamic photographic model based on the geometric theory of satellite imaging is worked out and the model parameters are piecewise optimized. The original image is coarsely sampled and then the optimized model is used to geometrically correct the image on each sample point. In this way, a "fictitious control-point network" is found. In order to quicken the correction speed, quasi-linear transformation is used in the network to interpolate in space. Grey resampling is then used to complete the geometric correction and output the image that has been corrected geometrically. By this method, fewer ground control-points are needed and good geometric correction accuracy and high speed can be achieved. Experimental results are satisfactory. The method proposed is suitable for geometric correction of satellite images with serious geometric distortion and large scanning angle. |
