ROBOT CONTROL DEVICE, ROBOT, ROBOT SYSTEM, AND CALIBRATION METHOD OF CAMERA FOR ROBOT

An processor moves an arm to rotate a calibration pattern around three rotation axes linearly independent from each other and to stop at a plurality of rotation positions. A processor causes a camera to capture a pattern image of the calibration pattern at the plurality of rotation positions. A proc...

More Information
Summary:An processor moves an arm to rotate a calibration pattern around three rotation axes linearly independent from each other and to stop at a plurality of rotation positions. A processor causes a camera to capture a pattern image of the calibration pattern at the plurality of rotation positions. A processor estimates parameters of the camera for calculating a coordinate transformation between a target coordinate system and a camera coordinate system using a pattern image captured at the plurality of rotation positions.
