Embodiment 1

[0044] This embodiment provides a two-dimensional code scanning device, such as figure 2 , image 3 shown, including:

[0045] scan camera;

[0046] The light source is fixedly connected to the scanning camera, and the light emitted by the light source forms a preset angle with the lens orientation of the scanning camera, and the preset angle is an acute angle;

[0047]The controller is connected with the scanning camera and the light source, and is used to control the light source to emit light, control the scanning camera to move to multiple different positions of the two-dimensional code array, and control the scanning camera to take multiple photos of the two-dimensional code array, so that the two-dimensional Each QR code in the code array is identified.

[0048] In a specific implementation process, the scanning camera may use an area array camera, and the corresponding light source may use a strip light source; or, the scanning camera may use a linear camera, and th...

Embodiment 2

[0076] Based on the same inventive idea, such as Image 6As shown, this embodiment provides a two-dimensional code scanning method, including:

[0077] Step S101: controlling the light source to emit light;

[0078] Step S102: Control the scanning camera to move to multiple different positions of the two-dimensional code array, and control the scanning camera to take multiple pictures of the two-dimensional code array, so as to identify each two-dimensional code in the two-dimensional code array.

[0079] In a specific implementation process, the light source is fixedly connected to the scanning camera, and the light emitted by the light source forms a preset angle with the lens orientation of the scanning camera, and the preset angle is an acute angle. Wherein, the value range of the preset angle is: 30 degrees to 60 degrees, for example, it may be: 30 degrees, or 45 degrees, or 60 degrees, and so on. Here, it is preferably 45 degrees. At this time, the light emitted by the...

Embodiment 3

[0100] Based on the same inventive idea, such as Figure 7 As shown, this embodiment provides a computer-readable storage medium, on which a computer program 711 is stored, and when the computer program 711 is executed by a processor, the following steps are implemented:

[0101] Control the light source to emit light; control the scanning camera to move to multiple different positions of the two-dimensional code array, and control the scanning camera to take multiple pictures of the two-dimensional code array, so that each two-dimensional code in the two-dimensional code array to identify.

[0102] Wherein, the light source is fixedly connected to the scanning camera, and the light emitted by the light source forms a preset angle with the lens orientation of the scanning camera, and the preset angle is an acute angle. Preferably, the preset angle is 45 degrees.

[0103] As an optional embodiment, when the scanning camera is an area scan camera and the light source is a stri...

Abstract

The invention discloses a two-dimensional code scanning device, comprising: a scanning camera; a light source, fixedly connected with the scanning camera, the light emitted by the light source forms a preset angle with the lens orientation of the scanning camera, and the preset angle is an acute angle; a controller, connected with the scanning camera The scanning camera and the light source are connected to control the light source to emit light, control the scanning camera to move to multiple different positions of the two-dimensional code array, and control the scanning camera to take multiple pictures of the two-dimensional code array, so as to scan the two-dimensional code array Each QR code is identified. The invention solves the technical problems of low recognition accuracy, low recognition efficiency and difficulty in recognizing the two-dimensional codes at the edge of the camera field of view when recognizing the two-dimensional code array etched on the metal surface in the prior art, and realizes Improve the recognition accuracy, improve the recognition efficiency, and the technical effect of a high one-time recognition rate. At the same time, the invention also discloses a two-dimensional code scanning method.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a two-dimensional code scanning device and a two-dimensional code scanning method. Background technique [0002] A two-dimensional code is a black and white pattern distributed on a plane (two-dimensional direction) according to certain rules with a specific geometric pattern, which is used to record data symbol information. QR codes are widely used in the Internet of Things, payment and other fields. At the same time, when companies manufacture products, they usually mark each product with a QR code to record and track product information for easy management. QR codes can be printed on paper or etched into metal surfaces. [0003] At present, mainstream two-dimensional code scanning devices, such as figure 1 As shown, it is mainly composed of a scanning camera (mostly an area scan camera) and a dome light source. The light of the dome light source is parallel to the lens o...
