Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments this utility model made into
One step describes in detail.
As shown in Figure 1, a kind of many bar codes position detecting system based on Vision Builder for Automated Inspection, it includes visual system master
Machine, light source and image capture module, described visual system main frame includes mainboard module, the internal memory that is connected with mainboard module, hard
Dish, light source control module and image transmitting interface, described light source is connected with described light source control module, described image acquisition mould
Block is connected with described image transmitting interface.In the present embodiment, described image capture module preferably has the work of GIGE interface
Industry camera, correspondingly, described image transmitting interface is preferably GIGE interface；Described internal memory is preferably DDR4 internal memory, described hard disk
For SSD solid state hard disc.
As preferred embodiment, described mainboard module is also associated with communication interface modules, such as USB module or WIFI mould
Block, in order to communicate with external equipment.
In the present embodiment, described mainboard module includes image pre-processing module, the bar code feature extraction mould being sequentially connected with
Block, bar code zone location module and bar code identification module.It is preferred that bar code zone location module includes region, bar code left and right
Locating module and bar code lower regions locating module, to realize the identification of any direction bar code.
As preferred embodiment, it is connected between described bar code feature extraction module with described bar code zone location module and has
Slant correction module, in order to be identified after the bar code tilted is carried out rotation correction；Described bar code zone location module with
Connect between described bar code identification module and have bar code region adjusting module, to prevent the feelings that leakage code occurs during bar code identification
Condition occurs.
Operation principle or the work process of many bar codes position detecting system of the present embodiment offer are described briefly below: pass through
Industrial camera and coordinating of light source obtain the view data with bar code information, and by the transmission of this view data to described vision system
The mainboard module of system main frame carries out image procossing, thus realizes bar code identification, and mainboard module is carrying out image procossing and realizing bar
The key step that code identifies includes:
(1) Image semantic classification step, is carried out at image pre-processing module；In the label of many bar codes, to reduce operand
For target, image is carried out label and separates with background, the interference of overanxious background, image is filtered, denoising, enhancing and two
Values etc. process；
(2) bar code characteristic (bar code feature) extraction step, is carried out in bar code feature extraction module；Bar code (barcode)
It is the multiple secret notes and blank that width is not waited, according to certain coding rule arrangement, in order to express the figure mark of one group of information
Knowing symbol, the feature therefore arranged according to the bar shaped of bar code carries out extracting correlated characteristic information；
(3) slant correction step, is carried out in slant correction module；Owing to some label with bar code is to tilt to put
Put, process again after needing its image is carried out rotation correction；
(4) bar code zone location step, is carried out in bar code zone location module, include bar code left and right zone location with
Bar code lower regions positions, to realize the location of all bar codes in many bar-code labels；
(5) bar code region set-up procedure, is carried out in the adjusting module of bar code region, for the situation of anti-leak-stopping code；This reality
Execute and example predominantly prevents the situation of left and right leakage code from occurring, the right boundary of bar code is extended 15 pixels respectively, is true simultaneously
Protect the stability of bar code identification, then up-and-down boundary to bar code reduces 15 pixels and processes respectively；
(6) bar code identification step, utilizes described bar code identification module to carry out, after identifying result, by corresponding communication
Module (USB module or WIFI module, or can also is that other communication interface modules) transmit to the most required equipment.
Certainly, during the image procossing carrying out above-mentioned steps and bar code identification, each functional module can be as required
It is integrated in one or more functional module/processor and carries out.
Many bar codes position detecting system based on Vision Builder for Automated Inspection that the present embodiment provides, can effectively replace traditional bar
Code reader, even to tilt bar code, single many bar codes of label, the many bar codes of single file, the bar code of excalation, have spot etc.
Relatively satisfactory recognition effect can be obtained, and the automatization that can realize any direction bar code and many bar codes identifies, and identify
Speed is fast, recognition efficiency advantages of higher, thus can effectively meet the demand that the extensive automatic industrial of enterprise produces.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, not
