Abstract
A method and device for drawing an outline of a region and a computer-readable storage medium are provided. The method includes: updating an original region outline map according to a first predetermined algorithm to obtain a first region outline map; updating the original region outline map according to a second predetermined algorithm to obtain a second region outline map; acquiring and processing first distance data obtained by a laser radar to generate a first to-be-matched outline map; comparing the first to-be-matched outline map with the first region outline map and the second region outline map, respectively; and replacing the second region outline map with the first region outline map if the similarity between the first region outline map and the first to-be-matched outline map is higher than the similarity between the second region outline map and the first to-be-matched outline map.
