摘　　要：针对景象匹配制导系统中弹载摄像机拍摄的实时图相对于弹体中预存的基准图存在较大的变形,严重影响到景象匹配精度的问题,提出一种基于惯导提供的位姿信息的图像校正算法,将弹载摄像机拍摄的实时图转换成与基准图同一个拍摄角度和高度条件下的图像。实验结果表明该算法校正精度高,鲁棒性强,极大地提高了景象匹配的精度。Due to the gross distortion between the real-time image collected by camera fixed in the missile and the base image stored in the missile, the precision of image matching is influenced seriously, so a precise image rectification algorithm is presented. Based on the attitude and position information provided by missile, the rectification algorithm can switch the real-time image to the image from the same view of the based image. Experimental results indicate that the algorithm presented is excellent in precision and robustness, and it can improve the precision of matching greatly.
