Problems solved by technology
[0004] The above method is the mainstream solution to barcode scanning on arc-shaped containers. However, for some products that pursue beautiful design or non-assembly line standardized production, there is still the possibility of barcodes being attached horizontally on arc-shaped containers.
When the length of the barcode is long and the radius of the arc-shaped container is short, when the reading device scans the barcode, the ratio of elements such as bars and spaces in the obtained barcode image will change. If the deformation is serious, the decoding will produce errors or operation failed

The invention provides binocular barcode reading equipment suitable for an arc-shaped container. The reading equipment comprises two rotational planes, wherein a camera and an infrared distance measurement module are arranged on each rotational plane, the two cameras are used for collecting barcode images located in a first region and a second region of the arc-shaped container respectively, and each of the two infrared distance measurement modules is used for measuring the distance between the corresponding rotational plane and the surface of the arc-shaped container and controlling the corresponding rotational plane to stop rotating when it is detected that the distance between the corresponding rotational plane and the arc-shaped container is minimum. The reading equipment also comprises a processor used for performing barcode column width correction on the first barcode image and the second barcode image to obtain the first barcode image and the second barcode image after correction, and splicing processing is performed on the two barcode images obtained after correction to obtain an intact target barcode image. Through the equipment, reading of barcodes on the arc-shaped container can be realized, and the success rate of barcode recognition on the arc-shaped container is increased.
Description
technical field [0001] The invention relates to the field of barcode reading, in particular to a binocular barcode reading device suitable for arc-shaped containers. Background technique [0002] Bar codes are arranged according to certain coding rules and can express specific information. They are widely used in the process of commodity identification and circulation. The expression of information in the barcode needs to go through two processes of scanning and decoding, in which the quality of barcode scanning directly determines the success or failure of decoding. [0003] For the barcode attached to the square container, there is no distortion of the barcode when scanning, which basically does not affect the decoding effect; for the barcode attached to the curved container, especially when the container has a large arc, the barcode will be seriously damaged when scanning. Deformation seriously affects the decoding effect. To avoid this problem, the current barcode is u...
