Abstract

The invention provides a construction method of an index map, an autonomous navigation method and device and electronic equipment. The index map construction method comprises; acquiring an index map mapping table; Identifying unknown index identification information in the target area, and determining a coordinate position corresponding to the unknown index identification information; And establishing a new mapping relation between the unknown index identification information and the corresponding coordinate position, and updating the index map mapping table based on the new mapping relation.The map of the target area obtained by the invention is an index map; namely, each coordinate point in the target area directly corresponds to index identification information; the coordinate positions are not directly corresponding; According to the map material preparation method, a large amount of repeated material preparation is not needed, the material preparation waste is reduced, the map rectification workload is reduced, the map rectification time is shortened, and the technical problems that in the prior art, the map material preparation waste is serious, and the map rectification workload is large are solved.

Description

technical field [0001] The present invention relates to the technical field of robot control, in particular to an index map construction method, an autonomous navigation method, a device and electronic equipment. Background technique [0002] Sports equipment usually needs to solve the following three problems during the walking process: first, determine its current position; second, determine the position at the next moment; third, determine how to reach the position at the next moment. Among them, the first problem is the positioning and tracking problem in the mobile device navigation system, and the second and third problems are the path planning problem in the navigation system. The task of sports equipment navigation and positioning technology is to solve the above three problems. Sports equipment perceives the environment and its own state through sensors, and then realizes autonomous movement towards the target in an environment with obstacles. This is usually refer...
