Document Type and Number:
WIPO Patent Application WO/2020/171007
Kind Code:
A1
Abstract:
An orientation sensor outputs orientation data indicating the orientation of a vehicle body. A position sensor is attached to the vehicle body. A storage device stores machine data. The machine data indicates the position of the position sensor in a vehicle body coordinate system. An input device receives the input of calibration data. The calibration data includes the position of a prescribed measurement point on a work machine as measured by an external measurement instrument, and the position of the position sensor as measured by the external measurement instrument. A processor calibrates the machine data on the basis of the calibration data and the orientation data.
