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...
