说明：  VC毕业设计，全景图拼接算法实战源码+论文。算法基本思想，图像A和Ｂ，Ａ有至少１／３部分与Ｂ重合，在Ａ中找图像块ａ，在Ｂ中找图像块ｂ，利用夹角余弦距离，求ａ 、ｂ的相似度，利用循环使ｂ在Ｂ中移动，找到相似度最大的图像块ｂ。通过ｂ所在点坐标，确定B相对于Ａ的偏移量。通过偏移量将Ａ和Ｂ放在同一坐标系实现拼接。(VC graduation design, panorama mosaic algorithm actual source code + thesis. The basic idea of the algorithm is that at least one third of the images A and B overlap with B. Find the image block a in A, and find the image block b in B. Use the cosine distance of the angle to find the similarity of a and b. Use the loop to move b in B to find the image block b with the highest similarity. Determine the offset of B relative to A through the coordinates of the point where b is located. A and B are placed in the same coordinate system through the offset to achieve stitching.)
