摘　　要：针对基于LOD模型的卫星地图显示系统中对图像处理的需要,提出了一种多幅图像旋转拼接算法,该算法在常规几何旋转算法的基础之上,将多幅图像的旋转拼接分成了两个部分:先进行子图像的旋转,然后确定子图像旋转后所得到的新图像在屏幕坐标系中的位置并显示。给出了详细的推导过程,并在Visual C++环境下予以了实现,结果表明该方法思路简单清晰,便于实现,为多幅图像的旋转拼接提供了一种通用的算法。An algorithm for many images＇ rotation and joining is proposed for satellite map system based on LOD model. Applying geometrical rotation principle, the images processing is divided into two parts： first, rotate every parted image, second, educe the rotated image＇s coordinates in the screen reference frame and display them. Detailed deductive process is afforded and the algorithm is realized with Visual C＋＋, Experiments show that the proposed algorithm is brachylogical and can be easily realized, so it would be a universal algorithm for many images＇ rotation and joining.
