Problems solved by technology
However, in the existing visual sweeping robots, due to factors such as insufficient map accuracy, inaccurate map obstacle marking, and inaccurate tracking path of the navigation robot, it is easy to cause the robot to deviate from the original navigation target direction during the navigation process. As for the subsequent robot deviation from the navigation path, it will affect the navigation efficiency of the robot.

The invention discloses a robot navigation path inflection point selection method, a chip and a robot, and the inflection point selection method comprises the steps: firstly selecting a target inflection point from a navigation path, respectively judging whether the target inflection point and one or two inflection points which are successively arranged from the target inflection point along the navigation advancing direction of the navigation path have the final navigation target point to select a preset inflection point meeting a guide condition; wherein the navigation advancing direction ofthe navigation path is a robot navigation direction used for guiding a robot to move to the final navigation target point; wherein the final navigation target point belongs to the end point of the navigation path. According to the method, the representative inflection points capable of guiding the robot to move back to the navigation path are screened out by judging whether the three inflection points continuously arranged on the navigation path of the robot have the end point of the navigation path.
Description
technical field [0001] The invention relates to the technical field of robot navigation, in particular to a method for selecting an inflection point of a robot navigation path, a chip and a robot. Background technique [0002] Controlling robot navigation is to control the robot to walk from one coordinate point on the map to another coordinate point. Generally, it searches for a path from the map first, and then walks according to this path until it reaches the target point. However, in the existing visual sweeping robots, due to factors such as insufficient map accuracy, inaccurate map obstacle marking, and inaccurate tracking path of the navigation robot, it is easy to cause the robot to deviate from the original navigation target direction during the navigation process. As for the subsequent robot deviation from the navigation path, it will affect the navigation efficiency of the robot. Contents of the invention [0003] In order to solve the above technical problems,...
