Embodiment 1
[0049] This embodiment discloses a glass bottle laser code detection method. In this embodiment, the image recognition method is used to identify the characters engraved by the laser on the glass bottle. If the match is successful, the glass bottle is qualified, otherwise, the glass bottle should be rejected. Specific methods such as figure 1 shown, the steps include:
[0050] S1: obtain a first character string, the first character string is the RFID tag symbol on the glass bottle to be detected;
[0051]The first character string is obtained through identification by a dual-frequency RFID system, and the dual-frequency RFID system adopts the UHF protocol and the HF protocol to identify the RFID tag.
[0052] In step S1, because there is a corresponding electronic label on the glass bottle after being engraved by the laser, and the electronic label records the label of the glass bottle or the anti-counterfeiting code, etc., the RFID tag is used for identification in this em...
Embodiment 2
[0078] This embodiment discloses a glass bottle laser code detection system. This embodiment implements the detection method in Embodiment 1, including a character acquisition module, an image acquisition module, a processing module, a feature extraction module, and a judgment module.
[0079] The character acquisition module is used to acquire a first character string, where the first character string is an RFID label symbol on the glass bottle to be detected;
[0080] The image acquisition module is configured to acquire a first image, where the first image is an image of a laser code on a glass bottle to be detected;
[0081] The processing module is used for preprocessing the first image to obtain first data;
[0082] The feature extraction module is used to extract and identify the feature symbols in the first data to obtain a second character string;
[0083] The judging module is configured to judge whether the first character string matches the second character string...

Abstract
The invention discloses a glass bottle laser code detection method and a detection system. A first character string is obtained, wherein the first character string is an RFID label symbol on a glass bottle to be detected; a first image is obtained, and the first image is The laser code image on the glass bottle to be detected; the first image is preprocessed to obtain the first data; the characteristic symbols in the first data are extracted to obtain the second character string; the first character is judged Whether the string matches the second string, if so, the glass bottle to be detected is qualified; otherwise, the glass bottle to be detected is rejected. The beneficial effects of the invention are to realize the process of automatic detection of the laser code of the glass bottle on the assembly line, improve the detection efficiency of the glass bottle; reduce manual operation, improve the detection speed of the laser code of the glass bottle, and save cost and time.
Description
technical field [0001] The invention relates to the technical field of laser code detection, in particular to a glass bottle laser code detection method and detection system. Background technique [0002] In recent years, with the development of the market economy, counterfeit products have also appeared, especially in the form of glass bottles, such as beer bottles, soy sauce bottles, vinegar bottles, etc., usually in order to prevent the appearance of counterfeit products. The corresponding anti-counterfeiting label is pasted on the corresponding glass bottle, and the manufacturer's relevant anti-counterfeiting label number is printed by laser engraving, so as to check whether the purchased product is a counterfeit product by detecting the label number; In the prior art, the code on the glass bottle after laser engraving is usually detected to prevent errors in laser engraving. The conventional detection method is to manually detect the code after laser engraving. The eff...
