Abstract

The invention provides a method and a device for identifying second-generation identity cards based on intelligent mobile equipment. The method comprises the following steps: acquiring an image of a second-generation identity card by a camera; performing gray calculation and binarization processing on the image of the second-generation identity card to acquire binary image data; horizontally projecting the binary image data to acquire each black block; acquiring the region of citizen identification number information according to the black blocks; acquiring the name information region and the address information region according to a preset second-generation identity card template. According to the method, when the second-generation identity card image is processed, gray calculation, binarization processing, horizontal projection, vertical projection, relative coordinate position and other basic algorithms are used, and the algorithms can run conveniently in the intelligent mobile equipment; a second-generation identity card image shot by the method only needs to comprise content to be identified, the method is low in image shooting requirement, can be applied to the intelligent mobile equipment, and can be used by users conveniently.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for identifying a second-generation ID card based on an intelligent mobile device. Background technique [0002] Now the second-generation ID card identification technology has been widely used in railway stations, but the algorithm of the existing second-generation ID card identification technology is relatively complicated, and an independent second-generation ID card scanner is required, so the existing second-generation ID card identification The technology is mostly used in large-scale equipment, and the existing second-generation ID card recognition technology adopts the edge detection method to identify the character position. This method has high requirements for the image of the second-generation ID card obtained by the scanner, and needs In view of the above reasons, the existing second-generation ID card technology is inconvenient for users to use in...
