宁波大学数据结构project3迷宫maze

基于MFC、opencv、VS2017的实现迷宫自动生成和路径求解，写的比较烂。
问题分析：
1.如何生成迷宫：随机生成、prim算法生成
2.如何求解迷宫：dfs、bfs等遍历方法
3.图形化界面联动：opencv图片刷新、时间控制、MFC等
必要的资源：VS2017，opencv-3.4.1
第一步、看一下文件的布置：
创建好工程后记得在下图目录下新建image这个文件夹
然后将这几张图片放入image下
如下图所示：
第二步、由于本人直接在project3Dlg.cpp里面写了全部，其他文件没有动过，可能需要将里面的图片路径改掉，所以直接上代码：
