Embodiment Construction
[0058] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0059] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.
[0060] After actual testing, it is found that when the computing power of the embedded processor is limited, it takes a long time to calculate the image scanning lines with different angles and slopes. If this part of the calculation time has been processed on the host c...

The invention provides a multi-angle scanning method, terminal equipment and a computer readable storage medium and relates to the field of one-dimensional code scanning technology. The method comprises the steps that a scanning angle of scanning a to-be-scanned image is acquired; the scanning angle is uploaded to an upper computer, and the upper computer calls an appropriate oblique position coordinate system, wherein the appropriate oblique position coordinate system is an oblique position coordinate system, corresponding to an oblique angle which has a minimum difference value with the scanning angle and is saved, in an oblique position coordinate system set; the appropriate oblique position coordinate system transmitted back by the upper computer is received; and picture feature data of the to-be-scanned image is acquired through coordinate values of pixels of the to-be-scanned image in the appropriate oblique position coordinate system. According to the method, by directly corresponding coordinates of the one-dimensional code image with an oblique angle to angle coordinate values in the oblique position coordinate system corresponding to the oblique angle, the picture feature data of the to-be-scanned image is acquired, and therefore the identification speed of one-dimensional code features is increased.
Description
technical field [0001] The invention belongs to the technical field of one-dimensional code scanning, and in particular relates to a multi-angle scanning method, terminal equipment and a computer-readable storage medium. Background technique [0002] A one-dimensional code is a mark composed of a set of regularly arranged bars, spaces and corresponding characters. "Bar" refers to the part with low reflectivity to light, and "space" refers to the part with high reflectivity to light. These bars and The data composed of blanks express certain information, and can be read by specific equipment and converted into binary and decimal information compatible with computers. At present, most of the solutions for soft decoding through one-dimensional codes convert the collected pictures in YUV (YCrCb, TV color coding method) format into grayscale pictures through one-dimensional code embedded processors and then binarize them. Scan the binarized picture that conforms to the character...
