Title:
CALIBRATION METHOD AND DEVICE FOR ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/061673
Kind Code:
A1
Abstract:
A calibration method for a robot, comprising executing a camera calibration process, wherein executing a camera calibration process comprises the following steps: capturing an image of an environment and forming a three-dimensional virtual object of the environment (301); placing a calibration object (403) in a target area of the environment on the basis of the captured image of the environment and the three-dimensional virtual object of the environment (302); using a first camera (102) to capture an image of the calibration object (403) by means of relative movement between the first camera (102) associated with a robot (101) and the calibration object (403) (303), wherein the first camera (102) is a 2D camera; and determining, on the basis of the image of the calibration object (403) captured by the first camera (102), a parameter of the first camera (102) used for calibration (304). According to the calibration method, a user (107) can be guided to perform camera calibration by means of an AR technology, such that operation is intuitive and convenient, operation complexity is reduced, and accuracy is improved. The present invention further relates to a calibration device for a robot.
