A method and system for reading machine-readable information in an image

Abstract

The invention discloses a method and system for reading the machine-readable information of an image, and the method comprises the steps of judging whether a to-be-processed Chinese-sensible image code exists in a view field, carrying out the image collection and image feature value extraction according to preset time, and comparing an extracted image feature value with a standard feature value library; when an extracted image feature value exists in the standard feature value library, extracting scale information and orientation information of the image, establishing a coordinate system of reading information, performing image feature value analysis according to an information reading mode, performing regional sampling on the acquired image, searching an image feature format information region, and reading stored image feature format information; reading and obtaining image feature format information area information of the information graph code and obtaining pre-coding format information; and according to the indication of the relevant prior information of the image feature format information area, carrying out corresponding pre-coding information demodulation and information acquisition, and carrying out corresponding error correction decoding and information decoding to obtain the original coding information in the image.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image information processing, and in particular to a method and system for reading machine-readable information inside an image. Background technique [0002] In the process of rapid development of information technology, the problem of information collection and information acquisition has always been the core issue in the process of information technology research and development and application. At present, there are two main methods of automatic information acquisition. One is to collect sensing information through image cameras, temperature and humidity sensors, microphones, etc., to convert the signals in the information collection area of ​​the sensing equipment into data information, and further pass the mode The method of identifying and classifying and extracting features is processed and transformed into valuable information that can be utilized by the information syst...

AI Technical Summary

Problems solved by technology

[0014] For this reason, the embodiment of the present invention provides a method and system for reading machine-readable information inside an image, which solves the problem that image acquisition and sensing devices such as cameras can only obtain image processing and perform pattern recognition, and the category information of items and images cannot be extracted. Accurately identify defects, through the judgment of known or unknown graphic images or specific area features, to obtain regularly arranged data modules related to image identification, thereby greatly improving the information collection efficiency and reliability of the information collection system
