Abstract

The invention relates to an identity card text positioning method and device, computer equipment and a storage medium. The method comprises the steps of obtaining an initial identity card image; carrying out image vertex determination on the initial identity card image by adopting a first convolutional neural network to obtain vertex coordinates of the identity card; performing outer frame positioning on the initial identity card image according to the vertex coordinates of the identity card to obtain a to-be-positioned identity card image; carrying out text line vertex determination on the to-be-positioned identity card image by adopting a second convolutional neural network to obtain vertex coordinates of a text line; performing textbox positioning on the to-be-positioned identity card image according to the vertex coordinates of the text line to obtain a text line image; and outputting the text line image to the terminal to enable the text line image to be displayed on the terminal.The convolutional neural network model adopted by the method is relatively small in scale, low in requirement on the operation environment, high in positioning accuracy and high in robustness.

Description

technical field [0001] The invention relates to an ID card identification method, and more specifically refers to an ID card text positioning method, device, computer equipment and storage medium. Background technique [0002] Identity cards are documents used to prove the identity of the holder, and are mostly issued to citizens by the governments of various countries or regions. It will be used as a tool to prove each person's unique citizenship. The ID card is attached with text information, and the text information generally indicates the identity information of the corresponding person. ID card text positioning is a key part of the ID card recognition algorithm, and whether the text position positioning is accurate directly affects the effect of text recognition. [0003] The existing ID card text positioning method is to use traditional image recognition methods for text positioning, such as denoising the image first, and then performing grayscale, binarization, conto...
