Example Embodiment

[0055] Please refer to figure 1 , The first embodiment of the present invention is:

[0056] A dual-camera scanning gun includes a housing 1, a near-focus camera 2 and a far-focus camera 3. The housing 1 is provided with a scanning window 11, and both the near-focus camera 2 and the far-focus camera 3 are installed in the At the scanning window 11, the near focus camera 2 and the far focus camera 3 are horizontally arranged side by side. It is convenient to align the near-focus camera 2 and the far-focus camera 3 to the scanned barcode at the same time.

Example Embodiment

[0057] Please refer to figure 1 , The second embodiment of the present invention is:

[0058] A dual-camera scanning gun, on the basis of the first embodiment, further includes a fill light 4, a laser positioning light 5, an optical grid, a buzzer, and a scanning button 6, the fill light 4 is installed in the housing 1 at the scanning window 11; preferably, the fill light 4 is symmetrically installed at the left and right edges of the scanning window 11 of the housing 1; the laser positioning lamp 5 is installed at the scanning window 11 of the housing 1 The laser positioning lamp 5 is installed between the close-focus camera 2 and the far-focus camera 3, or the laser positioning lamp 5 is installed on the outer side of the close-focus camera 2 or the outer side of the far-focus camera 3, The laser positioning lamp 5 is a high-brightness infrared focusing LED lamp, and the optical grid is installed in front of the laser positioning lamp 5; the buzzer is installed in the housing 1...

Example Embodiment

[0096] Please refer to figure 2 , The third embodiment of the present invention is:

[0097] A dual-camera scanning gun scanning method, the method is:

[0098] Obtain the first barcode image through the close focus camera, and at the same time acquire the second barcode image through the far focus camera;

[0099] Decode the first barcode image and the second barcode image, specifically:

[0100] The first barcode image and the second barcode image are decoded simultaneously in a dual-thread mode;

[0101] After one of the first barcode image and the second barcode image is successfully decoded, the decoding cancel command is sent to the thread where the other barcode image is located to cancel the decoding of the other barcode image.

Abstract

The invention provides a bi-camera scanner gun and a scanning method thereof. The bi-camera scanner gun includes a housing, a near-focus camera and a far-focus camera. The housing is provided with a scanning window thereon. The near-focus camera and the far-focus camera are both installed on the scanning window. The method includes the following steps: the near-focus camera acquiring a first bar code image, and at the same time the far-focus camera acquiring a second bar code image; decoding the first bar code image and/or the second bar code image. The bar code images are acquired by the near-focus camera and the far-focus camera having different depths of focus, and the bar code images are decoded, such that the usage of the scanner gun is expanded, the time for manual adjustment of the scanner gun is shortened, the time for code scanning of the scanner gun is reduced, and the sensitivity of code scanning is increased.

Description

technical field [0001] The invention relates to the technical field of barcode scanning, in particular to a dual-camera scanning gun and a scanning method thereof. Background technique [0002] In order to expand the payment function of the cash register system such as POS machines and cash register computers, a barcode scanning gun is connected to the cash register system terminal to scan and decode barcodes to realize fast code scanning payment. Existing barcode scanning guns all use a camera to scan codes, and a camera only has a fixed depth of field range. According to the needs of customers, install a camera with a suitable depth of field. Usually the depth of field of the camera ranges from 3 to 100mm, or 50 to 100mm, which limits the scope of use of a single scanner. [0003] The Chinese invention patent with the publication number CN103861275A discloses an improved scanning device design. A scanning device has multiple cameras. The error of one or more previous sca...
