Abstract

An embodiment of the present invention provides a computer imaging and defect identification system for weld defects, the system includes: a film feeding device, including an inner drum structure, used to attach a curved imaging plate, and the film feeding device is used to drive the The imaging plate moves along the axial direction of the inner drum structure; the laser scanning device is used for circularly scanning the imaging plate with a laser, and realizes line-by-line scanning of the imaging plate as the imaging plate moves; An image data acquisition device is used to collect the fluorescent information excited by the imaging plate, and convert the fluorescent information into digital information; an image processing and defect identification device is used to process the digital information to generate weld image information, and Carry out defect recognition on the generated weld seam image; control processing device, used to control the operation of the film feeding device, the laser scanning device and the image data acquisition device.

Description

technical field [0001] The invention relates to the technical field of laser scanning and weld image processing and defect recognition, in particular to a computer imaging and defect recognition system for weld defects. Background technique [0002] At present, X-ray imaging is mainly used in medical treatment by replacing X-ray film with X-ray imaging plate (IP). Its use method is the same as that of traditional X-ray film. , Compton scattering and other factors will weaken the X-ray energy. After X-ray irradiation, the information of the irradiated part of the human body is stored on the IP as a latent image, but its linear range is much larger than that of ordinary X-ray film, up to 1:10000. [0003] The image information stored in the IP will be reused after disappearing in the form of ultraviolet radiation under the light, and its radiation intensity is related to the light conditions. The IP is excited by a red laser with a constant light intensity and a certain wavel...
