Problems solved by technology
[0005] In order to solve the problems of low screening accuracy, poor robustness, time-consuming and poor stability existing in the existing ID card screening technology, the present invention discloses an efficient screening method for ID card photos. The face in the ID card determines the approximate area of the ID card, and the text line detection is performed in this area, and the text line rules that meet the ID card information are set according to the text line detection results, thereby filtering out non-ID card photos

Embodiment Construction
[0032] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0033] First, the server needs to process the images taken by hardware devices such as mobile phones, and then use the method of the present invention to intelligently judge whether the images contain clear ID card information, so as to achieve the purpose of screening. The overall step process of the present invention is as figure 1 shown. First, face detection is performed by rotating the original image by 90° in turn. If a face is detected, it is rotated to the horizontal according to the detected face angle, and then intercepted to obtain a rough ID card area. After that, it is detected through the trained text. The deep learning model detects the text lines...

The present invention discloses an efficient method for screening ID card photos. The method is characterized in that: a rough area of an ID card is determined by finding a face in an image, text linedetection is performed in the area, and a text line rule conforming to the ID card information is set by using the text line detection result, so that non-ID photos are screened. According to the method disclosed by the present invention, the blur edge, the noise, the incomplete circle and other interferences of the photos under different illumination environments can be coped with, the anti-interference ability is strong, a very low false positive rate is maintained, and high screening accuracy and short time are ensured; and compared with manual screening and screening by using the traditional image processing method, the method disclosed by the present invention performs better in comprehensive performance, can meet actual needs, and has robustness and high efficiency.
Description
technical field [0001] The invention belongs to the technical fields of computer vision and image processing, and relates to an image screening technology, more specifically, to an efficient ID photo screening method. Background technique [0002] In recent years, with the improvement of people's living standards, the business of banks and other aspects is busy, and the business windows of credit card processing and other aspects are even more busy, and due to the interest in the Internet, direct online processing has become the key. Handling this kind of business online requires a variety of personal information, the most important of which is the ID card, that is, you need to upload the photo of the ID card you have taken. The amount of such photo data is very large. If the ID card can be intelligently screened before the staff perform the final information check, it will greatly facilitate the staff and improve work efficiency. [0003] Existing screening methods include...
