Study Of Metallic Surface Image Inspect And Measure System

As the image inspect and measure system may quickly obtain abundance information, and they are prone to automatically disposed of, also are prone to integrate with design information and machining and control information, its study and development become a new trend of image project, and applied in various domain of industry production. The wear degree of cutting tools are usually inspected by workers or measured by indirect way in traditional metal cutting and manufacture industry. The advantages of image inspect are accurate, quick, credible and digital compared with manuwork inspect. It is main study content that develop a sort of image inspect and measure system applied in metal cutting and manufacture industry. The system are composed of Daheng video acquire card, Panasonic CCD, Computar M1214-MP FA, CCS LED lamp-house, the general stereoscopic vision microscope, the image processing computer. Calibrate this system use rule of three, and calibration precision arrives at application requirement.The mostly functions of the image inspect and measure system are acquiring and processing images, segmentation of images and measure images. It can automatically differentiate and pick-up available information of the original image, such as area and perimeter, by image processing and segmentation; may semiautomatically measure the location of a spot on the image, the length of lines, area size; may automatically detect distances between edges by edge detection; at the same time have common functions of minitype image processing software, such as addition or subtract of images, morphological processing and image segmentation. A new filter method that average many same size images when acquire images are proposed. Log_Prewitt edge detection operator are also proposed, which directly deal with light density consequently get rid of the affection by asymmetrical light and succeed to the smoothness of Prewitt operator, improve the anti-jamming of inspection.
