兰勃托地图投影绘图，包括兰伯特坐标转换，VC++语言-Lan Botuo map projection drawings, including the Lambert coordinate transformation, VC++ language

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。- Images A and B, A and at least 1/3 of the overlap B, find a picture in A block, looking for an image block b in B, usin
