Title:
ROBOT CALIBRATION METHOD AND SYSTEM, ROBOT AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/214147
Kind Code:
A1
Abstract:
Provided are a robot calibration method and system, a robot and a storage medium, the calibration method comprising controlling a frond end of the robot to move according to a pre-set rule (S101); detecting the change condition of a grayscale value caused by the movement, and recording a movement distance of the front end (S102); calculating a coordinate of an original position of the front end in a visual coordinate system and a coordinate of the calibration point in a robot coordinate system (S103); and according to the coordinate of the original position in the visual coordinate system and the coordinate of the calibration point in the robot coordinate system, calculating and obtaining a conversion relationship between the robot coordinate system and the visual coordinate system (S104). The precision of the conversion relationship between the robot coordinate system and the visual coordinate system can be improved by means of the method.
