The lower part of rate is penetrated, " sky " refers to the higher part of light reflectance, these letters certain with the data representation of empty composition
Breath, and can be distinguished with specific equipment, it is converted into the binary system and decimal system information compatible with computer.Generally for each
Kind article, its coding are uniquely, for common one-dimensional bar code, also to pass through Database bar code and quotient
The corresponding relationship of product information carries out data by the application program on computer when the data of bar code pass on computer
It operates and handles.Therefore, common one-dimensional bar code is only used as identification information in use, and significance of which is by counting
It extracts corresponding information in the database of calculation machine system and realizes.Data on bar code include start-up portion, data portion
Divide, terminate part.
For the ease of reading bar code, every on packing case 4 of the invention is provided with a bar code 5 on one side, and
The content of bar code is identical.
The safe ex-warehouse system operation method of image recognition provided by the invention, including following procedure step:
(1), at least one bar code scanning head is at least one bar code success on the cargo passed through on main belt
It reads, and obtains bar code data；Bar code data is imported into data processing module；Cargo is from main belt after continuing
It walks.
(2), when bar code scanning head fails to read any bar code on cargo, cargo is dialled in correction and is transmitted
Band.
The reason of failing to read any bar code on cargo has very much, for example is likely to be too fast, three items of walking
None is at functionality scan to bar code for bar code scanning unit, but this possibility is very little, will not occur substantially.And most
Chief reason is then that the bar code of every one side has damaged, pollution on cargo, thus unreadable.But pollution with breakage be with
Machine, therefore, when damaged or pollution occurs simultaneously for three bar codes on a packing case, and each pollutes and breaks
The same contaminated and damaged this probability of damage bar code be again it is very little, will not occur substantially.
Due to these three bar codes be one packaging on, the contained data of these three bar codes be it is identical, also
Be three bar codes content it is identical, show on figure, the figure of three bar codes all should be identical.
Therefore, three functional parts by damaged or pollution and damaged bar code are combined, so that it may constitute one
A complete bar code, so that scanning obtains bar code data.
The upper surface of cargo on correction conveyer belt is dialled in camera alignment on correction belt, the left side, the right side are imaged,
By the image of camera intake at least three bar codes on three faces on cargo, and three figures that three faces are absorbed
As being collected into rectification module.
Rectification module identifies bar code image part in each image, and knowing method for distinguishing can be using artificial intelligence training
Mode, church robot identify bar code.It can also be by the way of image recognition, that is, have the light and shade alternating of striated
Color lump, one piece from one piece of beginning to end, include middle section, it can regard as one group of bar code.Certainly, in order to know
The pixel of other bar code part is accurate, and other identification conditions can also be added.In short, will manually intelligent method, Huo Zhetu
As the method for pixel identification color lump, such as Gauss algorithm, the bar code part in image is accurately identified.
After recognizing the bar code part in image, remaining background colour block portion point is cropped.Three faces of packing case, are looked in total
To three bar codes (although there may be excalations for each bar code).
By the bar code image part found carry out correction image processing, removal saturation degree processing, adjust brightness comparison
It spends intensity, scratch except gray scale is 50% or less part, retain the black bar in bar code and as a figure layer.
Since bar code is mainly made of start-up portion, data portion, terminate part, pass through the training of artificial intelligence, energy
Start-up portion and terminate part are identified easily, as long as there is part identification correct, so that it may extrapolate other part, therefore can be with
Accurately know which is bar code part, which is background colour block portion point.
When correcting image processing, four angle points of bar code are calculated, stretched, extended accordingly.
Saturation degree processing mainly removal form and aspect information is removed, grayscale information is only retained.
Liang Du Dui Bidu intensity is adjusted, keeps light and shade contrast strong, can clearly identify the blank parts in bar code
Dark strip part (the exactly bar code of (being exactly " sky " of bar code, refer to the higher part of light reflectance) and bar code
" item " refers to the lower part of light reflectance).
It scratches except gray scale is 50% or less part, and sharpens edge.
It is partially basically that blank parts in bar code (are exactly " sky " of bar code, refer to pair that gray scale, which is 50% or less,
The higher part of light reflectance).Therefore, just only the dark strip part of remaining bar code has pixel, remaining nothing to whole image
Pixel (or few graininess pixel).
Three bar codes, each all after above method is handled, just obtains pixel clearly three bar codes
(although there may be excalations for each bar code).
With reference to Fig. 3, three bar codes, three figure layers are overlapped and to just as a figure layer by each, then,
The pixel of three figure layers is mutually filled, and is mutually filled a vacancy, and the folded figure of one group of new black bar is formed, from the appearance point of view, being exactly one complete
Whole bar code.
Using read module and complete bar code is read, obtains bar code data；Cargo walks on and imports again
To main belt rear end.
(3), when that can not correct reading bar code to obtain bar code data, cargo is dialled from correction conveyer belt
Enter onto rejecting branch.After the correction identification on top, the cargo entered in rejecting branch is only considerably less, has not exclusively system
Meter enters and rejects in branch less than the 0.007% of total gross traffic, is greatly lowered artificial workload in this way.
Above-mentioned is exemplary illustration of the invention, does not represent protection scope of the present invention.
