Abstract
A distance acquisition unit acquires first distance data that is distance data in an area in which a first reference object installed at an arbitrary position outside a work machine is present. The distance data is measured by an in-vehicle distance sensor. A position calculation unit calculates a position of the first reference object in a predetermined coordinate system based on the first distance data. A relationship acquisition unit acquires a positional relationship between the first reference object, and a second reference object of which a position in the coordinate system is known. A calibration unit calibrates, based on the first distance data and the positional relationship, a parameter to be used to measure a position in the coordinate system from the distance data of the in-vehicle distance sensor.
