Abstract
A control method for tracking a camera include following steps. At least one image involving a calibration chart is captured by a camera. A first trackable device attached to the camera is tracked by a tracking station to generate a first rotation-translation matrix. A second trackable device attached to the calibration chart is tracked by the tracking station to generate a second rotation-translation matrix. A third rotation-translation matrix is generated according to the calibration chart appeared in the at least one image. A fourth rotation-translation matrix is calculated between the camera coordinate system and the first trackable device according to the first rotation-translation matrix, the second rotation-translation matrix and the third rotation-translation matrix. The fourth rotation-translation matrix is utilized to track the camera.
