This article has first designed the hardware of the examination system, chose the appropriate hardware system according to the special production environment and the technics requirement of the Steaming stereotypia. Owing to production line work condition very severe, the temperature and pressure of the air is high, moreover included many corrosive chemical substance, the general industry camera was unable to work in this condition, so it must indirectly obtain a wiredrawing position image through the special lens, then transmitted to the CCD camera by the optical fiber. Transmit the image information to the PC system through the data-acquisition board. analysis the image information by the image-processing software, again send analysis result to the controller.
