Batch two-dimensional code identification method

Abstract

The invention discloses a batch two-dimensional code recognition method. The batch two-dimensional code recognition method comprises the steps: decoding, by a front-end processor, logistics box body pictures containing batch two-dimensional codes and photographied through a camera; writing into a touch display screen; decoding, by the front-end processor, colors of pixel points on the touch display screen line by line from left to right for recognition; when the color of the corresponding pixel point conforms to a color condition of the label, setting the pixel point as the upper left corner point, and searching the pixel point conforming to the color of the label from the upper left corner point to the right side and the lower side to obtain coordinates of the three corner points including the upper left corner point, the upper right corner point and the lower left corner point; and determining a rectangular contour according to the coordinates of the angular points, calculating the area S1 of a space defined by the rectangular contour, and, if the area S1 is larger than or equal to S0 and smaller than or equal to S2, reading the two-dimensional code in the space, storing the two-dimensional code and recording the coordinates of the three angular points. Batch two-dimensional code identification is carried out through a single lens, the obtained two-dimensional code repetition rate is low, and the damaged two-dimensional code identification effect is good.

Description

technical field [0001] The invention relates to the technical field of logistics, in particular to a batch two-dimensional code identification method. Background technique [0002] Logistics refers to the planning, implementation and management of raw materials, semi-finished products, finished products or related information from the place of origin to the place of consumption of goods in order to meet the needs of customers at the lowest cost through transportation, storage, distribution, etc. process. Logistics is a system of controlling raw materials, finished products, finished products and information, from the supply to the final consumer through the transfer and possession of various intermediate links, so as to achieve the clear goals of the organization. Modern logistics is a product of economic globalization and an important service industry that promotes economic globalization. The world's modern logistics industry is growing steadily, and Europe, the United St...

Problems solved by technology

[0005] The disadvantages of the two-dimensional code recognition system in the existing logistics technology are: first, it is necessary to set up a high-definition camera array to take pictures through the high-definition camera array, resulting in high cost; second, the obtained two-dimensional code has a high repetition rate, resulting in repetitive and confusing statistical data 1. The accuracy is low. The third is that the recognition effect on damaged QR codes is poor, and it is easy to cause repeated recognition statistics problems
