High-speed tagging method for laser device

Abstract

The invention relates to a high-speed tagging method for a laser device. The method is characterized in that any part of a dominant two-dimensional code or an invisible two-dimensional code is composed of a dot matrix of the same size, and a mark formed by a focus of the laser device, namely the size of each dot of a dot matrix of a two-dimensional code formed by the laser device is consistent with the size of the dot matrix corresponding to any part of the dominant two-dimensional code or the invisible two-dimensional code or approximate to the size of the dot matrixes corresponding to all parts of the invisible two-dimensional code. The method has the advantages that the size of each dot of the two-dimensional code formed by the focus of the laser device is reasonably matched with the two-dimensional dot matrix formed by dot matrixes in a unified size, so that tagging characteristics of the two-dimensional code laser device adapt to a dot matrix composition form and structure of a code; and when tagging of the same two-dimensional code is performed, laser emission times are reduced compared with a traditional method, and therefore high-speed tagging can be realized.

Description

【Technical field】 [0001] The invention belongs to a high-speed coding method of a laser in the field of image processing. 【Background technique】 [0002] With the concrete application of the concept of the Internet of Things, people finally see clearly that it is a de-conceptual practicability with less investment and quick results between popular mobile phone reading, connecting products to the Internet to realize product promotion, public anti-counterfeiting identification of products, and big data analysis of products. technology. [0003] Therefore, no matter what the product is, it has become a trend to realize public mobile phone identification through variable information coding. However, how to code products efficiently and at low cost has become a subject of attention. [0004] For this reason, there have been many publications on patents related to this aspect in the past year. In China, the German coding professional company Domiro published a bottle cap with a t...
