Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings.

[0053] Such as figure 1 As shown, a recognition device of Chinese Sensible Code under a complex background includes: a Chinese Sensible Code image with a complex background, a camera, a PC and a display, and the camera captures the Chinese Sensible Code image and sends the image to For a PC, the PC performs algorithm recognition on the image including positioning, correction, single character recognition, and decoding to obtain Chinese Sensible code information, and the display displays the Chinese Sensible code information.

[0054] The above-mentioned equipment rectifies the inclination of the secondary positioning of the Chinese Sensible code under a complex background, and obtains a standard code map, and quickly obtains the Chinese Sensible code information through single-character recognition and decoding. The specific process is as follows figure 2 As shown, a...

Abstract

The invention belongs to the field of two-dimensional code recognition, relates to applications of image processing and character recognition technology and discloses a Chinese-sensible code recognition device and a Chinese-sensible code recognition method under a complicated background. The method comprises the following steps of: collecting a Chinese-sensible code image with a complicated background; preprocessing the collected image; carrying out secondary positioning on a Chinese-sensible code in the image to obtain the accurate position of the Chinese-sensible code; carrying out slant correction on the Chinese-sensible code obtained by positioning, thus obtaining the corrected Chinese-sensible code; partitioning the Chinese-sensible code by using an edge detection and projection algorithm to obtain a single-line Chinese-sensible code, and then carrying out single-character recognition; decoding to obtain Chinese-sensible code information; and displaying the Chinese-sensible code information on a display screen. According to the method disclosed by the invention, the location accuracy is improved, the efficiency of algorithm is high, the rate is fast, the anti-interference property is strong, the robustness is good, single-character bar codes can be recognized rapidly and effectively, the bar codes can be recognized accurately, and the efficiency of Chinese-sensible code recognition is greatly improved.

Description

technical field [0001] The invention belongs to the field of two-dimensional code recognition, is the application of image processing and character recognition technology, and in particular relates to a Chinese Sensible code recognition device and method under a complicated background. Background technique [0002] In terms of two-dimensional code applications, China currently mainly relies on foreign technologies such as PDF417 and QR codes. These technologies have strict patent protection, so the related equipment is expensive and there are certain hidden dangers in information security. With the release of my country's first national standard for two-dimensional codes with completely independent intellectual property rights, Hanxin codes have gradually been used more and more in various aspects such as books and vehicle management. However, due to the characteristics of the application environment and external interference factors, the accuracy and robustness of Chinese ...
