Document Type and Number:
WIPO Patent Application WO/2023/166885
Kind Code:
A1
Abstract:
The present invention accurately calibrates information pertaining to a work machine by means of simple tasks. This information calibration method comprises: stopping a measurement target at at least three different measurement points in a plane, in order; measuring the posture of a work machine relative to a vehicle body when the measurement target is stopped at each measurement point; measuring the distance between each of the measurement points; and deriving information in which the difference is minimized between measurement point measurement coordinates based on the distances and in a coordinate system defined in the plane, and measurement point calculated coordinates calculated using the posture and the information, and updating the information.
