Problems solved by technology

[0004] There is a deviation between the actual position of the robot and the position of the two-dimensional code when the robot shoots the two-dimensional code, and the position information of the two-dimensional code captured by the robot is used as the current position of the robot, which leads to the accuracy of the current position of the robot. The accuracy is very low, and the error of positioning the robot position is very large

Embodiment 1

[0052] An embodiment of the present invention provides a method for locating the position of a robot. Among them, there are multiple two-dimensional codes in the working area of ​​the robot, and multiple optical marking points are set around each two-dimensional code. The multiple two-dimensional codes are arranged according to certain rules. The robot scans the two-dimensional code picture of the working area, And the scanned two-dimensional code picture is transmitted to the console in real time, and the console recognizes the position of the two-dimensional code in the two-dimensional code picture through the method provided by the embodiment of the present invention, so as to locate the two-dimensional code picture according to the shooting angle of the robot Find the position and angle of the robot. see Figure 1A , the method includes the following steps S101-S104:

[0053] Step S101: Receive the two-dimensional code picture taken by the robot, and obtain the central co...

Embodiment 2

[0079] see Figure 2A , the device for locating the position of the robot includes: a first acquisition module S1, an interception module S2, a second acquisition module S3 and a determination module S4.

[0080] The first acquisition module S1 is used to receive the two-dimensional code picture taken by the robot, and obtain the central coordinate point and angle of the two-dimensional code from the two-dimensional code picture;

[0081] The interception module S2 is used to intercept the picture of the optical marker point from the two-dimensional code picture according to the preset distance value and the central coordinate point of the two-dimensional code;

[0082] The second obtaining module S3 is used to obtain the central coordinates of the optical marking point from the picture of the optical marking point;

[0083] The determination module S4 is used to determine the current position and angle of the robot according to the central coordinate point of the two-dimensi...

Abstract

The invention provides a method and device for locating the position of a robot. The method comprises the steps of receiving a two-dimension code picture taken by the robot and obtaining the center coordinate point and the angle of a two-dimension code from the two-dimension code picture; capturing a picture of an optical mark point from the two-dimension code picture according to the preset distance value and the center coordinate point of the two-dimension code; obtaining the center coordinate of the optical mark point from the picture of the optical mark point; according to the center coordinate point of the two-dimension code, the center coordinate of the optical mark point and the angle of shooting the two-dimension code picture, determining the current position and angle of the robot. The position of the robot can be determined through the two-dimension code, the optical mark point and the angle of shooting the two-dimension code picture by the robot, the accuracy of determining the current position of the robot is improved, the error of locating the position of the robot is reduced, and therefore the accuracy of judgments made according to the located position of the robot is high, and the robot can be controlled to arrive at a destination fast.

Description

technical field [0001] The present invention relates to the technical field of robots, in particular to a method and device for locating the position of a robot. Background technique [0002] At present, with the rapid development of information technology, two-dimensional codes are widely used in various enterprises and various products. Two-dimensional codes collect relevant information about enterprises and products, and relevant information can be obtained by scanning two-dimensional codes. For example, an industrial robot obtains its location information by scanning the QR code set in the working area. [0003] At present, when an industrial robot obtains its own location information through a QR code, the industrial robot first captures the QR code set in the area through its own camera, and then parses the QR code to obtain the location information of the area where the QR code is located. , determine the position information of the two-dimensional code as the curren...
