Abstract

The invention relates to the technical field of image detection and image processing, and provides a certificate contour determination method, which comprises the following steps: obtaining a certificate image shot by a camera device, extracting line segments in a candidate region based on an Lsd linear detection algorithm, and obtaining first line segment sets corresponding to the candidate region respectively; obtaining line segment information of each line segment in the first line segment set, filtering the line segments in the first line segment set based on the line segment information,and obtaining a second line segment set corresponding to the candidate area; screening line segments in the second line segment set to obtain target line segments; and processing the target line segment to obtain the contour of the certificate image. According to the method, the success rate of line segment detection is improved, the influence of weak boundary, background and size factors on certificate image contour extraction is avoided, the line segment extraction rate is increased on the basis of simple screening and filtering and improvement of the certificate image contour accuracy, andthe certificate image contour determination algorithm is simplified.

Description

technical field [0001] The invention relates to the technical fields of image processing and edge detection, in particular to a method, device, storage medium, and server for determining the outline of a certificate. Background technique [0002] Nowadays, more and more industries, such as the communication industry, hotels, Internet cafes, etc., need to collect and register certificate information. In the context of Internet big data, it is the general trend to use modern information technology to carry out efficient, fast and convenient services. , It is also under this background that various types of document recognition software came into being. Document recognition software processes document materials based on pattern recognition, which belongs to the category of computer vision. [0003] In the prior art, most of the contour detection methods of certificates are based on edge detection algorithms, that is, edge detection is used to obtain the position of the border ...
