Abstract

The invention provides a polygon region detection method and device, a computer readable storage medium and electronic equipment. The polygon region detection method comprises the steps: obtaining a to-be-detected image; calculating line segments in the image based on a straight line detection algorithm; merging the line segments meeting the merging conditions into a line segment; calculating a cross point between the combined line segments according to the combined line segments; and generating a polygon region in the image by taking the cross point as the vertex of the polygon region. By applying the polygon region detection method and device, the polygon region detection accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a polygonal region detection method, device, computer storage medium and electronic equipment. Background technique [0002] With the continuous development of image processing technology, there are more and more scenarios for detecting polygonal regions in images. For example, in the real-name authentication process, the user can upload a photo of himself and his ID card in the same frame, and the authentication system needs to detect the quadrilateral area where the ID card is located in the photo, so as to identify the ID card information. [0003] In related technologies, the detection of polygonal regions in an image mainly uses the LSD algorithm. The straight line segments in the image can be calculated by the LSD algorithm, and then a polygonal area is constructed based on these straight line segments. However, due to a large number of interference fac...
