Identity card image acquisition and recognition system as well as acquisition and recognition method based on contact type sensor

Abstract

The invention provides an identity card image acquisition and recognition system based on a contact type sensor, and an identity card image acquisition and recognition method based on the contact type sensor. The identity card image acquisition and recognition method sequentially comprises the steps that: S1) a terminal control system starts acquisition, obtains an identity card image through the contact type sensor, and uploads the identity card image obtained through acquisition to a terminal; S2) the terminal extracts useful information blocks of the identity card image by adopting an image segmentation algorithm; S3) the image in the corresponding blocks is subjected to pre-processing, and character segmentation is conducted in the blocks; S4) character images after segmentation are subjected to normalization processing, then character features are extracted, and the features are classified by using a classifier, and finally identity card information is recognized; S5) and the identity card image and information are automatically stored and the identity card image is printed. The identity card image acquisition and recognition method can achieve fast acquisition of identity card images and accurate recognition of identity card information, further supports terminals systems such as banks and customs in acquiring identity card images and entering identity card information quickly.

Description

technical field [0001] The invention relates to an ID card image collection and recognition technology, in particular to a contact sensor-based ID card image collection and recognition system and collection and recognition method; it belongs to the technical fields of image processing, machine learning, pattern recognition and digital signal processing Background technique [0002] The ID card is a symbol of the identity of the residents of our country, which records the basic personal information of citizens and the unique ID number. At present, most ID card registrations are manually entered, which is not only time-consuming, but also inefficient. Therefore, how to use computer technology to enter personal information efficiently and completely at a high speed, and perform corresponding management and verification has become an urgent problem to be solved in many information registration and entry systems. [0003] The traditional ID card image acquisition is taken by a c...

AI Technical Summary

Problems solved by technology

[0004] 1. The quality of the collected ID card image is not high, resulting in a low recognition rate in the later stage

[0005] 2. The background of the ID card image is complex: the background of the ID card is composed of shaded grid lines and laser anti-counterfeiting marks, which has caused a great obstacle to the extraction of useful information on the ID card

[0006] 3. There are many Chinese characters involved in the ID card, and the structure is complex, which is also a challenge for the recognition of Chinese characters
