Abstract: An automatic calibration system applied to a camera and a related automatic calibration method are disclosed. The automatic calibration method utilizes a motionless calibration plate to calculate a calibration parameter of the camera, the camera includes at least one image sensing unit, and the camera is assembled with a testing device. The automatic calibration method includes rotating the camera by a first shaft and a second shaft of the testing device to change an angle of the at least one image sensing unit of the camera toward the calibration plate, capturing a plurality of images containing the calibration plate by the camera while rotating, calculating the calibration parameter of the camera according to the images, and storing the calibration parameter.
