Abstract

A working apparatus comprises a working unit which executes work on a work subject, and a calibration jig on which a plurality of markers is arranged in a radial pattern from a center point of markers, the plurality of markers being arranged in three dimensions, and the calibration jig being attached to a working unit such that a calibration reference point set of a working unit coincides with a center point of markers. According to such a composition, it becomes possible to calibrate a position of a working unit even when a portion of the jig containing a center point of markers is occluded during image measurement.
