Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying a narrow-strip two-dimensional bar code. One of the methods includes obtaining an image of the narrow-strip two-dimensional bar code. A first positioning graph and a second positioning graph are detected in the image. A target region is determined from the image based on center positions of the first positioning graph and the second positioning graph, where the target region includes a rectangular region corresponding to the narrow-strip two-dimensional bar code. A data region is determined from the target region, and two-dimensional bar code data is determined from the data region.
