摘要：In this paper, an efficient methodology using GPS/IMU data for automatic point transformation in aerial triangulation is presented. It firstly performs matching within each strip. For point transformation between strips, with the help of GPS/IMU data, tie point's initial position in search image of neighboring strips can be easily obtained, with high accuracy of several pixels. Then correlation window warping procedure and multi-image matching in image space is used for matching. The former is to reduce the effect of geometric distortion due to terrain relief and orientation difference and the latter is to take advantage of redundant information provided by the multiple overlapped images to reduce image matching blunders. Experiments have been carried out to verify the method. It have shown that by integrating the GPS/IMU data in the point transfer, it can not only simplify the point transferring procedure but improve the matching success rate of tie points between strips, providing relatively more robust geometry structure for the bundle block adjustment
