The invention relates to a photographic device optical center position calibration method and device. Firstly, a marking point P fixed on the ground in working space of a photographic robot is selected, a tool point T at the tail end of the robot is selected, the positions of the tool point T and the marking point P in a robot coordinate system are determined, the robot is controlled to move, so that the tool point T reaches the marking point P, the position in the robot coordinate system is determined, a photographic device is further controlled to move, so that the marking point P is located in the center of a picture, the first position of the robot and the coordinates of the marking point P in the picture are recorded, a vidicon is further opened to do translation in the direction perpendicular to the optical axis of the vidicon,the marking point P is kept in the picture of the vidicon, the second position of the robot and the coordinates of the marking point P in the picture are recorded, and then the optical center position of the vidicon can be obtained through calculation according to known parameters. According to the calibration method, a special calibration plate is not needed, local materials are conveniently used, application is convenient, and the operation process is simple and easy to implement.
Description
technical field [0001] The present application relates to the field of special film and television shooting, in particular, to a method and device for calibrating the optical center position of a camera device. Background technique [0002] The camera robot is an important material shooting equipment for visual effects. The camera robot controls the movement of the camera, and its trajectory is accurately recorded and stored in the computer. The trajectory data can be edited and modified, and the shooting trajectory can be accurately reproduced, which cannot be achieved by manual operation. In practice, various layers of image materials shot with the same movement trajectory are used in the computer to produce a variety of complex special film and television effects, such as scaling, group effects, multiple shooting, etc., using 3D image software. [0003] In the shooting application, the camera is installed at the end of the robot. In order to accurately control the spatia...
