Abstract

The invention discloses an image collecting device and a collecting method aiming at pork skin laser burning codes. The characteristic that a laser burning part on the pork has weak fluorescence reaction on light with specific wavelengths is utilized, through shielding visible light and installing an ultraviolet light source with the specific wavelengths on collecting equipment, the laser burning part on the pork can give out fluorescence, and the fluorescence is collected by an image sensor, so the image collection of the laser burning codes is realized. The image collecting device has the advantages that very strong noise resistance performance is achieved, and the obtaining of machine-readable code information in images can be realized through further image processing and analysis.

Description

technical field

[0001] The invention belongs to the technical field of image acquisition, and in particular relates to an image acquisition device and acquisition method for laser burn marking on pork. Background technique

[0002] The blue quarantine stamp on pork will be replaced by a laser "ID card" in the future. The laser ID card on the pork is a kind of information generated by laser burning. The laser is used to burn the code on the skin of the pork, presenting a three-dimensional image with a concave-convex feeling. Pig laser burning quarantine marks can be used to improve the safety traceability of animal products and ensure the quality and safety of pork products.

[0003] Laser burning of live pigs does not contain any additives, and will not pollute the pork burned by the laser and the surrounding environment, but also poses challenges to the reading of information. With various light sources and general shooting methods, it is difficult to achieve the standard...
