[0291] (1) Eye-in-hand one-click calibration test on the sawyer robot:
[0292] a) The robot holds the camera and moves around itself to detect whether there is a calibration plate around (such as Figure 11 shown).
[0293] b) The camera detects the existence of the calibration plate, and the robot holds the camera and moves in different directions to estimate the orientation of the calibration plate in the robot coordinate system (such as Figure 12 shown).
[0294] c) The robot estimates the position of the calibration plate, and at this time the end of the mechanical arm has moved directly above the calibration plate (such as Figure 13 shown).
[0295] d) The robot takes the estimated position of the calibration plate as the center, rotates and samples the calibration plate, and records the position of the end of the mechanical arm in the camera coordinate system (such as Figure 14 shown).
[0296] e) Solving the calibration equation, the data collected during the c...
