Abstract

The invention discloses a two-dimensional code positioning and detection method, comprising the following steps: using an image acquisition device to acquire a first two-dimensional code image; processing the first two-dimensional code image to obtain a second two-dimensional code image; The second two-dimensional code image carries out edge detection, detects the edge information of each edge in the second two-dimensional code image, saves the hierarchical tree relationship of each edge according to the edge information; detects the edge information of the edge and the edge in the hierarchical tree relationship in sequence The sub-edge information of the sub-edge determines whether the edge contains a two-dimensional code area; and outputs the edge information of the edge containing the two-dimensional code area. The positioning and detection method of the two-dimensional code of the present invention can also realize accurate positioning and detection of the two-dimensional code area when there are multiple two-dimensional codes in the image, and at the same time, its detection efficiency and accuracy are high .

Description

technical field [0001] The invention relates to the field of information positioning and identification, more specifically, a method for positioning and detecting a two-dimensional code. Background technique [0002] Before the existing two-dimensional code in the picture is recognized, it is necessary to locate and detect the two-dimensional code in the photographed picture.
