Abstract
Indicators are set on a marker positioned on a working stage in conformity with a target teaching point. A stereo camera images the indicator in a state of being positioned on a robot hand, and measures the three-dimensional position of the marker. In robot arm controlling, the robot hand is positioned at the correction teaching point for off-line that is offset from an off-line teaching point in the depth of field direction of the stereo camera. In imaging, while the robot hand is positioned at the correction teaching point for off-line, the indicators are imaged by the stereo camera. In correcting, based on an imaging result of the indicator, the on-line teaching point is corrected toward the target teaching point to obtain the on-line teaching point.
