地图中等值线的识别与矢量化，可以实现从栅格地图（目前支持bmp,emf等文件）中获取等值线.GIS工程有用的。-contour map of identification and vectorization, can be achieved from the raster maps (currently supports bmp, catalog, etc.) access contours. GIS projects useful.

将数据信息转换为栅格地图，便于进行下一步的路径规划

MATLAB创建栅格地图源码，用于路径规划方面的地图创建(MATLAB create grid map source code for map building in path planning)
