Abstract

An auto-charging method comprises: shooting a charging pile in multiple visual angles by using an image collection unit of a mobile robot; constructing a three-dimensional profile of the charging pileaccording to images in the multiple visual angles, and determining a position of the three-dimensional profile of the charging pile in a movement space of the mobile robot; obtaining a current heading direction of the mobile robot in the space; and controlling the mobile robot to move towards the charging pile according to the current heading direction and the position of the three-dimensional profile of the charging pile. Based on this, the mobile robot can recognize and position the charging pile by using the three-dimensional profile of the charging pile. The present invention can be implemented to reduce problems of charging pile positioning failure caused by infrared ray signal inaccuracy, so that auto-recharging efficiency is improved. This application further provides a mobile robot that can implement the foregoing method.

Description

technical field [0001] The present application relates to the field of intelligent control, in particular to a method for autonomous charging and a mobile robot. Background technique [0002] In the prior art, infrared signals are used to locate charging piles and guide robots. Since the infrared signal is easily affected by the outside world, it will cause the robot to misjudge the location of the charging pile. This will cause charging failure. Contents of the invention [0003] In view of this, the present application provides an autonomous charging method and a mobile robot, which can improve the accuracy of the mobile robot in judging the orientation of the charging pile and improve the efficiency of autonomous charging. [0004] The first aspect provides a method for autonomous charging, including: using the image acquisition unit of the mobile robot to photograph the charging pile from multiple viewing angles; constructing the three-dimensional outline of the char...
