PURPOSE:To eliminate the fear of an erroneous recognition and obtain a highly reliable image of an object within a short period of time, by installing a TV camera in premises with a specific mounting angle with respect to the coordinates in relation to the premises. CONSTITUTION:An industrial TV camera is installed in premises with any mounting angle other than 45 deg., for example 30 deg., with respect to the coordinates in relation to the premises. By so doing, among objects of detection including circular and square ones, it is possible to easily obtain the center position of only a circular object, whose symmetricalness does not change with the mounting angle of the TV camera, and three is no fear of an erroneous recognition. |
