Abstract

The invention discloses an obstacle boundary generation method and device, and the method comprises the steps: recording the coordinates of an obstacle when self-walking equipment encounters the obstacle, collecting the coordinates of a plurality of obstacles with the distances meeting the requirements into an obstacle point set, generating an obstacle boundary based on each obstacle point set, and updating a map. Therefore, in the working process of the self-walking equipment, the map information of the self-walking equipment can be synchronously updated on the basis of the response action ofthe self-walking equipment to the obstacle. According to the invention, the obstacle boundary in the map range can be accurately updated so as to accurately control the robot to walk by itself.

Description

technical field [0001] The invention relates to the technical field of self-propelled control, in particular to the boundary of obstacles in the self-propelled process. Background technique [0002] The mobile robot includes a navigation control module and a motor drive module in order to realize self-propelled function. The navigation control module outputs corresponding control signals to the motor drive module according to the map information stored by the mobile robot, and the motor drive module controls the operation of the motor to realize the self-propelled control of the mobile robot within the map range. [0003] The self-propelled control described above depends on map information. Therefore, in order to realize the simultaneous positioning and map construction of the mobile robot, it is necessary to continuously update the map information during the movement of the robot. A very important part of it is to judge and update the obstacles in the map. [0004] When...
