Title:
MECHANICAL ARM CALIBRATION METHOD AND APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/077912
Kind Code:
A1
Abstract:
A mechanical arm calibration method and apparatus, and a computer-readable storage medium. The mechanical arm calibration method comprises: acquiring height data of the axis of a bucket of a mechanical arm in real time; controlling the movement of the mechanical arm to make the axis of the bucket be maintained at a preset height, and collecting first data and second data of the mechanical arm during the movement process; calibrating a boom and an extending arm according to the first data, the second data and the preset height; controlling the movement of the mechanical arm to make a claw tip of the bucket be maintained at a preset point location, and collecting third data of the mechanical arm during the movement process; and calibrating the bucket according to data from a third attitude sensor. Height data of the axis of a bucket is acquired as reference data to calibrate a mechanical arm, such that the operation difficulty is lower; and only the height data of the axis of the bucket needs to be measured during a calibration process and it is not necessary to perform other operations, such that the calibration process is simpler.
