Problems solved by technology

In some cases, such as with the help of GPS, the robot can obtain the precise coordinates of its own position, however, in some cases where it is not easy to obtain precise coordinates, positioning and navigation will encounter great difficulties

Abstract

Embodiments of the invention provide a control method and electronic equipment. The control method is applied to one or more electronic devices used for map construction and route navigation in an environment, including: acquiring feature information of route nodes in the environment, wherein the route nodes are those that need to be routed in the environment or have route turning points nodes; obtain the number information of each of multiple nodes with the same characteristic information; obtain distance information and azimuth information about each path node; and, based on the characteristic information, number information, distance information and azimuth angle of the path node information for map building and route navigation within the environment. Through the control method and the electronic device according to the embodiments of the present invention, accurate path identification can be realized without requiring precise coordinates of path nodes, and the overall cost can be reduced.

Description

technical field [0001] The present invention relates to a control method and electronic equipment. Background technique [0002] SLAM (Simultaneous Localization and Mapping: Simultaneous Localization and Mapping) is also known as CML (Concurrent Mapping and Localization: Simultaneous Mapping and Positioning), which refers to instant positioning and map construction. SLAM was first proposed by Smith, Self and Cheeseman in 1988. Due to its important theoretical and application value, it is considered by many scholars to be the key to realizing a truly fully autonomous mobile robot. [0003] SLAM can be described as: when the robot starts to move from an unknown position in an unknown environment, it locates itself according to the position estimation and the map during the movement, and builds an incremental map based on its own positioning, so as to realize the robot's Autonomous positioning and navigation. [0004] Among them, in the process of exploring the unknown enviro...
