The embodiment of the invention also provides a kind of methods of data processing, illustrate as to Fig. 1 the method, such as
Whether include that bar code can be implemented by following manner in step 102, detection Target Photo shown in Fig. 2:
Step 201 is scanned Target Photo, obtains two dimensional code set of characteristic points, and two dimensional code set of characteristic points are used for
Positioning and identification two dimensional code.
Step 202, to judge whether the distributing position of each two dimensional code characteristic point in two dimensional code set of characteristic points meets default
Distributing position.
The characteristic point of two dimensional code is as shown in figure 3, be located at three apexes of image in 2 D code.By detecting target figure
The position of each two dimensional code characteristic point in the two dimensional code set of characteristic points identified in piece, can determine two dimensional code set of characteristic points
In each two dimensional code characteristic point can determine a two dimensional code.Specifically, three two dimensional codes in detection two dimensional code set of characteristic points
Whether characteristic point can constitute a square, if can if meet default distributing position.
It should be noted that the number of the two dimensional code characteristic point scanned in Target Photo is not only three.If
Less than three, then Target Photo is not two dimensional code.The two dimensional code characteristic point then scanned since first if it is greater than three,
The position for finding out the two dimensional code characteristic point scanned with first meets two two dimensional code characteristic points of predeterminated position.The two two
The image-region that dimension code characteristic point and first two dimensional code characteristic point scanned are drawn a circle to approve is image in 2 D code.If from two dimensional code
The position for not finding out the two dimensional code characteristic point scanned with first in set of characteristic points meets two two dimensional codes of predeterminated position
Characteristic point the two dimensional code characteristic point then scanned since second, finds out the two dimensional code characteristic point scanned with second
Position meets two two dimensional code characteristic points of predeterminated position.And so on, it detects and whether there is energy in two dimensional code set of characteristic points
Enough determine three two dimensional code characteristic points of an image in 2 D code.
If the distributing position of each two dimensional code characteristic point step 203a, in two dimensional code set of characteristic points meets default distribution
Position, then Target Photo includes two dimensional code.
When the Target Photo includes two dimensional code, step 103 is executed, when in Target Photo including two dimensional code,
When passing through Photo Viewer displaying target picture, display bar code recognition prompt.
If the distributing position of each two dimensional code characteristic point step 203b, in two dimensional code set of characteristic points does not meet default point
Cloth position, then Target Photo, which does not include, two dimensional code.
When Target Photo, which does not include, two dimensional code, Target Photo is normal picture, executes step 204 at this time.
Step 204, when passing through Photo Viewer displaying target picture, display interface keeps original display mode.
In use, there are following two kinds of situations: 1, as shown in figure 3, Target Photo is an inherently Zhang Erwei
Code picture, then user can intuitively know that the picture is two dimensional code, can be identified.2, as shown in figure 4, part in Target Photo
Region is two-dimension code image, and user ignores the two dimensional code in figure by being easy in fast browsing.The method as shown in Fig. 2 be
It is carried out before displaying target picture, therefore can be in displaying target picture, two-dimensional code display identification according to testing result mentions
Show, and then user is avoided to slip, improves the service efficiency of picture.
The method of data processing provided in an embodiment of the present invention can be scanned scanning Target Photo, obtain target
All meet the two dimensional code set of characteristic points of two dimensional code characteristic point in picture.By whether being deposited in detection two dimensional code set of characteristic points
In three two dimensional code characteristic points for meeting predeterminated position, achieve the effect that detect in Target Photo with the presence or absence of two dimensional code.In turn,
It prompts that there is identifiable two dimensional code in ownership goal picture, improves the service efficiency of picture.
The embodiment of the invention also provides a kind of methods of data processing, illustrate as to method shown in Fig. 1, step
Rapid 102, the step of whether including bar code is detected in Target Photo, can be implemented by following manner:
Characteristic area scanning is carried out to the Target Photo, the characteristic area is for indicating one-dimensional bar code.If swept
The left margin area and right blank area of bar code are retouched, then the Target Photo contains bar code, and the left margin area is used for
The initial position of the bar code is identified, right blank area is used to identify the rest position of the bar code.
The method of data processing provided in an embodiment of the present invention can carry out characteristic area scanning to the Target Photo,
If the left margin area and right blank area of bar code are arrived in scanning, the Target Photo contains bar code, reaches detection mesh
It marks on a map and whether there is the effect of bar code in piece.In turn, it prompts that there is identifiable bar code in ownership goal picture, mentions
The service efficiency of high picture.
When showing normal picture, as shown in Fig. 5-a, Photo Viewer shows row's icon in lower section, such as returns to figure
Mark shares icon, picture attribute icon.The embodiment of the invention also provides a kind of methods of data processing, as to shown in Fig. 1
Method illustrates, if including bar code in detection Target Photo, shows that bar code recognition prompts in step 103, can
Implemented by following manner:
Mode one: the picture attribute icon in the Photo Viewer is replaced with into bar code recognition icon.
As shown in Fig. 5-b, picture attribute icon is replaced with into bar code recognition icon, includes to identify in Target Photo
Bar code.
Mode two: the display reminding function key on the predetermined position of Photo Viewer contains text in the prompt facility key
This prompt information, the text prompt information is for indicating that the Target Photo includes identifiable bar code.
As shown in Fig. 5-c, in the lower section of the picture of display, with the nonoverlapping position display reminding function key of icon.Prompt
The text prompt information that function key is shown is " identification bar code ", " scanning bar code " etc. can for indicating that Target Photo includes
The bar code of identification.
Mode three: scanning list item is shown in picture attribute menu.
As shown in Fig. 5-d, user clicks picture attribute icon, starts picture attribute menu.It is shown in picture attribute menu
Show new scanning list item, scanning the word content in list item can be " scanning bar code " or " identification bar code ".User's point
Bar code recognition can be started by hitting the scanning list item.
In addition, user can determine that the picture is to need to identify picture in resource manager by picture name.Resource
Manager is that electronic equipment is the management software for managing storage file that user provides, and user can be right in resource manager
Stored file such as is renamed, is deleted, replacing storage location at the operation.At this point, when the user clicks in resource manager
When starting the attribute menu in picture, new scanning list item is shown in attribute menu, scanning word content in list item can be with
It is " scanning bar code " or " identification bar code ".User, which clicks the scanning list item, can start bar code recognition.
The method of data processing provided in an embodiment of the present invention, can be by showing bar code recognition in Photo Viewer
Icon adds the mode for scanning list item in picture attribute menu, includes that can know in the picture for prompting user currently to show
Other bar code.When the user clicks the bar code recognition icon or scanning list item when, directly to the bar code in Target Photo
It is identified, reduces the operating procedure of bar code recognition.
The embodiment of the invention also provides a kind of methods of data processing, illustrate as to method shown in Fig. 1, such as
Shown in Fig. 6, step 105 identifies the bar code in the Target Photo of reading, can be implemented by following manner:
Step 601 obtains image in 2 D code from Target Photo.
Image in 2 D code is the picture area that three two dimensional code characteristic points are drawn a circle to approve in Target Photo.
Image in 2 D code is carried out binary conversion treatment by step 602, obtains bianry image corresponding with image in 2 D code.
When carrying out binary conversion treatment, threshold theory can be used, that is, set a first threshold T, with T by image in 2 D code
Pixel be divided into two: greater than pixel of T and the pixel less than T.Pixel greater than T is expressed as " 1 ", and the pixel less than T indicates
For " 0 ", and then complete binaryzation.Obtained bianry image is made of the binarized pixel that " 0 " and " 1 " indicates.
Step 603 is partitioned into image to be decoded from bianry image.
Specifically, as shown in fig. 7, comprises:
Step 701 carries out dilation operation to bianry image.
In bianry image with structural element and moved on bianry image, if having a point and image in structural element
In the value of point be identical the point in image just to be replaced with into result element.
Step 702 carries out edge detection to the bianry image after dilation operation, obtains two dimensional code profile.
It extracts in the pixel of bianry image with the big side of brightness value (gray scale) direction in space gradient, line feature.Edge inspection
The data volume that edge data can be greatly reduced is surveyed, and interference pixel can be rejected, while retaining the structure of bianry image
Attribute.
Step 703 is partitioned into image to be decoded out of two dimensional code profile.
When being split, following (1) or (2) can be used or (3) are implemented:
(1) symbol is split using the method that region increases, two dimensional code boundary is corrected with this.
Since a zonule (seed) in two dimensional code, two dimensional code boundary is corrected by region growth, two dimension
All the points in code are included in this boundary, specific:
1) to Grid square point, single-frame net unit is scanned, the end operation when can not find such culture point；
2) the Grid square point 8 neighborhood points adjacent with surrounding are compared, if being less than second threshold, is merged into same area
Domain, and the label in the region is assigned to combined culture point；
3) since the culture point newly merged, operation 2) is repeated；
4) operation 2), 3) is repeated, until can not be merged；
5) it returns and 1) operates, find new Grid square point.
(2) entire symbol is partitioned by convex hull calculating.
Convex hull can be regarded as the boundary of point set, and explication is as follows:
If the set that the k point that set S is n-dimensional space forms, i.e. S=x1, x2 ... xk }, xi is n-dimensional vector.Define S
Convex hull Conv (S) are as follows:
Conv (S)=x=λ 1*x1+ λ 2*x2+...+ λ k*xk | k=1 λ 1+ λ 2+...+ λ }.
(3) increased using region and convex hull calculates alternately.
It is repeated twice if the pixel density of two dimensional code is bigger.If the pixel density of two dimensional code is sparse,
It then needs at least to be repeated four times.
Step 604 is decoded image to be decoded, obtains code word data corresponding with image in 2 D code.
Pixel value is read according to preset order from image to be decoded, the two-value data of " 0 " " 1 " expression is obtained, from prestoring
Mapping table in find out the corresponding code word data of the two-value data.Code word data can be picture or text information, or
Network address etc..
Step 605 executes the corresponding operation of code word data.
If it is network address, then network is accessed according to the network address.If it is figure disk or text information, then the picture or text are shown
Word information.
It should be noted that matrix two-dimensional code has an advantage that
1. high density encodes: information capacity is big: can accommodate up to 1850 capitalizations or 2710 numbers or 1108
Byte or more than 500 a Chinese characters are about tens times higher than common bar code information capacity.
2. coding range is wide: the bar code can picture, sound, text, signature, fingerprint etc. can with digitized information into
Row coding, is showed with bar code；It can indicate multilingual text；It can indicate image data.
3. fault-tolerant ability is strong: there is error correction: when this makes two-dimensional bar code cause local damage because perforating, being stained etc.,
It can be correctly obtained recognition in the same old way, damaged area can still restore information up to 50%.
4. decoding high reliablity: it is more much lower than common bar code decoding error rate 2/1000000ths, and the bit error rate is no more than
Thousand a ten thousandths.
5. encryption measures can be introduced: confidentiality, antifalsification are good.
6. at low cost, easy to manufacture, durable.
7. bar code symbol shape, size variable-scale.
The method of the data processing provided in the embodiment of the present invention, the identification suitable for matrix two-dimensional code.Due to matrix two
Dimension code has the above advantages, thus the method for data processing provided in an embodiment of the present invention have more stable recognition effect and
