Embodiment Construction

[0035] refer to figure 1 , an embodiment of the mobile robot provided by the present application includes: an image capture unit 110, a battery unit 120, a drive unit 130, a left wheel 131, a right wheel 132, a guide wheel 133, a cleaning unit 140, a processing unit 150, a storage unit 160, a detection Unit 170.

[0036] The image capture unit 110 is used to capture images in the working environment of the mobile robot. The image capturing unit 110 includes one or more cameras of a two-dimensional camera and a three-dimensional camera. For example, a two-dimensional camera may be placed on the upper surface of the mobile robot and capture an image of above the mobile robot, ie, an image of the ceiling of the space to be worked.

[0037] As another example, a 3D camera is placed at the front of the mobile robot and captures the 3D image viewed by the mobile robot. The three-dimensional image includes information about the distance from the object to be captured to the two-di...

Abstract

The invention provides an automatic charging method. The automatic charging method comprises the steps that a first environment image is captured, wherein the first environment image comprises a charging pile image; according to the charging pile image, two reference lines are extracted; according to the difference between a position relationship of the two reference lines and a preset position relationship of the two reference lines, a mobile robot is controlled to move towards a charging pile. According to the method, the mobile robot utilizes the charging pile image to recognize and position the charging pile. The automatic charging method can solve the problem of the positioning failure of the charging pile caused by inaccurate infrared signals, thereby improving the automatic recharging efficiency. The invention further provides the mobile robot capable of implementing the 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 robot in judging the orientation of the charging pile. [0004] The first aspect provides a method for autonomous charging, including: capturing a first environment image, the first environment image includes a charging pile image; extracting two reference lines according to the charging pile image; The difference of the preset position relationship of the r...
