Work apparatus and calibration method for the same

A work apparatus sets a virtual target point on an image plane in an imaging apparatus, and obtains a plurality of coordinate values of a moving unit at which a work reference point of a work unit and the virtual target point are caused to match in an image captured by the imaging apparatus. Further...

Beschreibung
Zusammenfassung:	A work apparatus sets a virtual target point on an image plane in an imaging apparatus, and obtains a plurality of coordinate values of a moving unit at which a work reference point of a work unit and the virtual target point are caused to match in an image captured by the imaging apparatus. Further, the work apparatus obtains, in the image, coordinate values of the moving unit at which a position of light projection by a distance information obtaining unit and the virtual target point are caused to match, and a plurality of pieces of distance information obtained from the distance information obtaining unit at those coordinate positions. Then, the work apparatus calculates, based on the plurality of coordinate values and the plurality of pieces of distance information obtained through the above processing, a calibration parameter for the moving unit and the distance information obtaining unit.
