Claim 16:
17. A non-transitory computer-readable storage medium storing computer instructions therein, wherein the computer instructions are used to cause the computer to perform a method for building landform map, wherein the method comprises:
acquiring a to-be-processed image to obtain a grayscale image of the to-be-processed image;
classifying pixels in the grayscale image according to grayscale values to obtain binary images corresponding to different landform categories;
extracting image spot contours of image spots in the binary images, and taking the extracted image spot contours as vector graphs to obtain a vector graph set;
merging, according to position information, the vector graphs corresponding to a same landform category in the vector graph set, and obtaining a first landform map according to merging results corresponding to different landform categories; and
mapping, by using a preset landform type, the vector graphs corresponding to different landform categories in the first landform map, and taking a mapping result as a second landform map.
