Abstract

The invention discloses a computer vision detection and tracing system and a method for laser marking software, and the system comprises an original image photographing module which is used for photographing a target and reserving a sample before marking; a marking module which is used for marking the target; a secondary photographing module which is used for photographing the marked target; a detection module which is used for analyzing the target picture before marking and the target picture after marking to obtain marking effect evaluation parameters; a storage module which is used for storing the marking effect evaluation parameters detected by the detection module; and an uploading module which is used for uploading the marking effect evaluation parameters. Whether marking is conducted and the marking effect do not need to be manually judged by personnel, and after equipment goes wrong, alarming and detection can be conducted at the first time. In addition, the marking conditionsof historical marked products can be inquired and traced through records. The product strictly calculates the effect according to the image similarity, and avoids the problems of fatigue, omission andthe like easily caused by visual inspection of personnel with complex marked images.

Description

Technical field: [0001] The invention relates to the technical field of laser marking, in particular to a computer vision detection and traceability system and method of laser marking software. Background technique: [0002] Laser marking technology is one of the largest application areas of laser processing. Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. Laser marking can print various characters, symbols and patterns, etc., and the character size can range from millimeters to microns, which has special significance for product anti-counterfeiting. [0003] At present, the detection of the existing marked parts is after the marking is completed, and the operator relies on experience to visually check whether the mark is marked or whether the marking effect is qualified. Relying entirely on human judg...
