Abstract
For the unsolved technology problem of fast automatic geolocation of airborne optical images,a high accurate,high efficient and good scalable method is proposed for geolocation of airborne remote sens-ing optical images is proposed. The method is centered on sensor collinearity equations. The real-time im-age and the sensor imaging parameters will be put into the collinearity model for geometric rectification. Then the rectified image is registered with corrresponding reference image. The matching points are used to update the sensor imaging parameters. Finally,the updated parameters and real-time image are put again into the sensor collinearity model for acquiring geometric location information. This indirect geolocation method,which is based on image registration and imaging model,not only reduces the computation,but also makes the automatic registration stable. It has a prominent advantage over traditional direct or image regis-tration methods. In addition,a strict error propagation formula is capable of computing the geolocation ac-curacy range. Simulation results show that even under the highly-oblique condition,a geolocation accuracy better than one hundred meters can be obtained with the proposed method.关键词
