Abstract

The invention discloses a two-dimensional code detection method, and relates to the field of map information collection, the method comprises the steps: carrying out the preprocessing of an original image, and obtaining a preprocessed image; extracting a frame of each graph area in the preprocessed image to obtain a graph frame; carrying out vertex extraction on the graph frame to obtain an undetermined area; wherein the number of the vertexes of the to-be-determined area is four; carrying out plane projection conversion on the image of the to-be-determined area to obtain a corrected image; And detecting images corresponding to the three position detection graphs in the corrected image. The invention further provides a two-dimensional code detection method and device and a storage medium,the two-dimensional code image in the image can be effectively detected, and the detection efficiency of two-dimensional code detection is improved.

Description

technical field [0001] The invention relates to the field of map information collection, in particular to a two-dimensional code detection method, device and storage medium. Background technique [0002] A two-dimensional code is a readable barcode, which records data through black and white images distributed on a plane according to certain rules according to a specific geometric figure. Two-dimensional codes have the characteristics of large information capacity and high reliability. Therefore, in application environments such as warehouse storage or workshop handling, two-dimensional code positioning technology, as one of the key technologies in AGV equipment control, is often used to navigate AGV equipment. and positioning. [0003] In the prior art, it is usually based on the acquired original image, through border extraction, to detect whether the image includes three position detection patterns of the two-dimensional code, and determine the position of the two-dimens...
