Specific embodiment
The specific implementation of the utility model is described in detail below in conjunction with attached drawing and specific embodiment.It needs to refer to
Out, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments, is based on this reality
It is obtained by those of ordinary skill in the art without making creative efforts every other with the embodiment in novel
Embodiment is fallen within the protection scope of the utility model.It is noted that the key of the utility model is to structure proposition
Technical solution, if relating to need the process of control or software realization below, it is existing to be that those skilled in the art can refer to
Mature technology programming is realized.
As shown in Figure 1, the hardware module figure of the barcode scanning device for a kind of dual camera of the utility model, including control
Device, camera module, lighting module, indicating module and communication module, the controller respectively with camera module, illumination mould
Block, indicating module and communication module link；The controller includes for controlling modules work, the camera module
One camera module and second camera module, first camera module and second camera module are used to obtain wait know
The image of object whole or regional area is read, there are overlay regions for the first camera module and second camera module acquired image
Domain.
Preferably, the communication module and external equipment it is wired or be wirelessly connected, for sending the bar code distinguished
And two-dimensional barcode information.
Preferably, the indicating module is also used as the light source of camera module, is shown in the center of finding a view of camera module,
For providing instruction for user.
Preferably, first camera module and second camera module, which are transversely mounted, is fixed on the same structural member
On.
Preferably, the camera lens axis parallel of first camera module and second camera module, and level height
Unanimously.
As shown in Fig. 2, the front layout drawing of the barcode scanning device for a kind of dual camera of the utility model, wherein first takes the photograph
It is fixed on the same structural member as the camera lens 1 of head module and the camera lens 2 of second camera module are transversely mounted, the axle center of camera lens
Line is parallel, and level height is consistent, and light is radiated at the first camera module and second camera mould by the light-emitting window 3 of indicating module
The central area of block, and instruction is provided for user, the light-emitting window 4 of lighting module acts on as light filling, the range that light irradiates is covered
The viewfinder range of lid the first camera module and second camera module.
As shown in figure 3, the coverage figure of the barcode scanning device for a kind of dual camera of the utility model, target object
The all images AFGD of all areas by the first camera module shooting image-region ABCD and second camera module bat
It takes the photograph image-region EFGH and overlapping region EBCH merges to obtain.
As an example, the lighting module of the utility model, communication module, controller can be using the same of existing barcode scanning device
Base part is realized, such as lighting module can realize that indicating module can be implemented in combination with by LED and lens, described by LED
The color of the emergent light of indicating module or brightness are different from the emergent light of lighting module.
Below as just applicating example.
As shown in figure 4, the process flow diagram of the barcode scanning device for a kind of dual camera of the utility model, in barcode scanning device
The image of camera shooting is usually black white image, also can be converted grayscale image, the gray scale of single pixel if it is color image
Value range is 0-255, and the judgment criteria of retroreflective regions is that the area image grey scale pixel value reaches or approaches 255, these judgements
It is all existing conventional techniques.
By judging that the first camera module is shot with the presence or absence of retroreflective regions in the overlapping region EBCH of image ABCD, if
There is no being then decoded using the image that the first camera module obtains, otherwise continue to judge second camera module photograph
It whether there is retroreflective regions in the overlapping region EBCH of image EFGH, the figure then obtained if it does not exist using second camera module
As being decoded, otherwise just illustrates that two images all have reflective phenomenon in overlapping region, need to reacquire first at this time and take the photograph
As head module and the newest image of second camera module, above-mentioned steps are carried out.
The recognition process flow of the utility model, disposable to obtain different angle two images, very high probability only has one
There is reflective phenomenon in image, and image quality better image is selected to be distinguished, and can save because distinguishing failure caused by reflective
And the time wasted, accelerate the reaction speed of barcode scanning device, avoid the need for the operation that user adjusts barcode scanning design factors repeatedly,
Improve the user experience of product.
It, can also be by judging overlapping region showing with the presence or absence of gray value too small (image is partially dark) using same method
As to select image quality, more preferably image is distinguished.
The image that first camera module and second camera module obtain can use merging algorithm for images, by two width
Image merges into the bigger image of a width, as the open source software openCV Sift and Surf algorithm provided can realize the spelling of image
It connecing, spliced image is not only that resolution ratio improves, from the surface of two angle shot curved surfaces and metal incision, depending on
Angle is more preferable, and picture quality is higher, can greatly improve the recognition rate of barcode scanning device.
In conclusion a kind of barcode scanning device of dual camera of the utility model has, resolution ratio is higher, can distinguish more
The advantages of strip shape code, while possessing more shooting angle, it can more preferably identify two dimensional code and metal watch in curved surface printing
The two dimensional code of face engraving, improves the recognition speed of two dimensional code.
