1. A control device that controls a robot having an arm provided with a calibration pattern of a camera and the camera provided independently of the arm, comprising:

  • a processor that is configured to execute computer-executable instructions so as to control the robot,wherein the processor is configured to;

    move the arm to rotate a calibration pattern around three rotation axes linearly independent from each other and to stop at a plurality of rotation positions,cause the camera to capture a pattern image of the calibration pattern at the plurality of rotation positions, anddetermine parameters of the camera for calculating the coordinate transformation between a target coordinate system having a known relative position and attitude with respect to a robot coordinate system of the robot and a camera coordinate system of the camera using the pattern image captured at the plurality of rotation positions.
