Title:
METHOD AND SYSTEM FOR AUTOMATICALLY ESTABLISHING MAP INDOORS BY MOBILE ROBOT
Document Type and Number:
WIPO Patent Application WO/2017/028653
Kind Code:
A1
Abstract:
A method and system for automatically establishing a map indoors by a mobile robot. The method comprises: form an initialized map (101); mark an origin of coordinates on the initialized map (102); a robot traverses feasible areas in a room, and records path information and environmental information (103); the robot calculates and marks CV values of all grids in the map (104); and establish a map according to the path information and the CV values (105), the path information and the CV values being obtained through calculation by using mathematical algorithms. By adopting a grid type map for modeling, real-time adjustment and correspondence of an indoor environment and grid information are realized, such that the validity of a map model is ensured; and furthermore, the grid type map is easy to maintain, convenient and fast in access of map data and wide in adaptability, and is capable of realizing rapid response to a diversified environment so as to rapidly create a dynamic map model which reflects real environmental information.
