Abstract
Disclosed is a method of correcting the position of a TV camera for taking up the image of an object to produce video signals of the image, suitable for use in, for example, automotive headlamp beam testing system. The images of reference points which are provided for the purpose of correcting the TV camera position are taken up by the TV camera. Then, the position data representing the positions of the reference points in the field of vision of the TV camera is determined. The position data are compared with predetermined reference point data representing the positions of the reference points in the field of vision of the TV camera as obtained when the TV camera is in the correct position, thereby determining the amount of deviation of the TV camera. Then, the driving unit is operated in accordance with the thus determined amount of deviation to adjust the optical axis of said TV camera so as to eliminate the deviation of the TV camera position. Disclosed also is a method in which the measurement data obtained through the TV camera is corrected in accordance with the amount of deviation of the TV camera, as well as an apparatus suitable for carrying out these methods.
