Under the conditions of graphic code itself is identifiable, in the image for graphic code identification of scanning, graphic code is blocked without recognizable,
Then can be by several different graphic code images, the graphic code image that synthesis meets identification condition is identified, and improves figure
The success rate of shape code identification.
Second embodiment
A kind of graphic code recognition methods is present embodiments provided, Fig. 3 is referred to, this method includes：
Step S210：Graphic code image is obtained, when the graphic code in the graphic code image obtained is unsatisfactory for identification condition
When, obtain several graphic code images.
When starting that graphic code is identified, if the single graph code image None- identified of acquisition, can obtain more
Width graphic code image.Wherein it is possible to be, one time recognition failures obtain several graphic code images or multiple single width figure
Barcode image recognition failures obtain several graphic code images；Either, in predetermined time period to graphic code None- identified,
Several graphic code images are then obtained, which does not limit in the embodiment of the present application, such as 3s.
Since mobile terminal is located at different location, when being scanned to graphic code, scanning angle is different, the figure got
In code image, position of the bad point in graphic code may be different.Or be, it is mobile whole when unlatching flash lamp is scanned
End position is different, and reflective spot of the flash lamp on Quick Response Code carrier is also different.For example, the figure that mobile phone is obtained at a position
Barcode image may be as shown in Figure 1, mobile phone be when another position is scanned, and camera camera site and/or angle change obtain
Graphic code image may be as shown in figure 4, position of the bad point in graphic code and being differed in two width figures.
Therefore, as an implementation, before obtaining several graphic code images, can first show to mobile terminal into
The mobile prompt message of row carries out different location, different angle is swept so that user moves mobile terminal to graphic code
It retouches, mobile terminal obtains the different graphic code image in bad point position in different location.
In addition, as an implementation, can also be, if the graphic code image None- identified obtained, to detect described
When mobile terminal moves, several graphic code images are obtained.Further alternative, Ke Yishi detects shifting when obtaining multiple image
Primary mobile, graphic code image of acquisition occurs for dynamic terminal location.Optionally, the movement of mobile terminal can be satisfaction one
The movement for determining mobile condition, as translational acceleration reaches certain preset value, movement speed reaches certain preset value, traveling time reaches certain
Preset value etc..
As an implementation, when graphic code None- identified in the graphic code image of acquisition, several figures are continuously acquired
Barcode image can have time interval between several continuous graphic code images, and specific time interval length is in the application
It is not limited in embodiment, such as 0.5s.Since user carries out with mobile terminals such as mobile phones in graphic code scanning process, hand is usual
It can occur to shake or deviate, to make mobile phone shake or offset, in different position acquisition to different graphic code image, acquisition
In different graphic code image, bad point is likely located at the different location in graphic code.
In the embodiment of the present application, above-mentioned various embodiments can individually be implemented, or be combined and implemented, and
Not as the restriction in the embodiment of the present application.
Optionally, graphic code itself can recognize that, and it is usually by flash lamp that the graphic code image scanned is not recognizable
Influence therefore in the embodiment of the present application, before obtaining several graphic code images, can also include：Judge described mobile whole
Whether the flash lamp at end lights；May be then to obtain several since the influence of flash lamp is graphic code None- identified if lighting
Graphic code image.If flash lamp does not light, it is likely that be graphic code itself there are it is damaged the problems such as and None- identified.
Wherein, graphic code None- identified is that graphic code is unsatisfactory for identification condition.The identification condition can be that graphic code is complete
Whole, that is, the graphic code got includes all figures in graphic code.
In addition, since there are graphic code some figures in certain serious forgiveness or graphic code must be read into, then should
Identification condition can also be that account for the ratio of graphic code total information fault-tolerant less than graphic code for the graphic code information that can not be read
Rate, and/or, the figure that must be read into graphic code is in the graphic code image got.
For example, Quick Response Code has certain serious forgiveness, has and store fault-tolerant rank, in error tolerance, even if Quick Response Code
It is occluded a part, can equally identify Quick Response Code, obtains whole QR code contents.In addition, having position sensing in Quick Response Code
Figure, the coordinate for determining each module in two-dimensional code symbol, if in the image in 2 D code obtained, the quantity of position sensing figure
Less than the preset quantity that can identify Quick Response Code, each module in Quick Response Code can not be positioned, which is unsatisfactory for presetting
Identification condition.Therefore, identification condition can be the graphic code information that can not be read account for the graphic code total information ratio it is low
The quantity for the position sensing figure that may be read into the serious forgiveness of the graphic code and the graphic code is more than present count
Amount.
After obtaining several graphic code images, can include according to the graphic code in several described graphic code images, acquisition
Meet the targeted graphical code image of the graphic code of identification condition.
In one embodiment, can multiple image be subjected to image synthesis, obtains a width graphic code and meets identification item
The image of part is as targeted graphical code image.
In another embodiment, can also be, using a width graphic code image as targeted graphical code image, to use other
Graphic code in graphic code image replaces the part that identification condition is unsatisfactory in targeted graphical code image.Specifically, in the implementation
In mode, may include：
Step S220：A width graphic code image is determined as targeted graphical code image, acquisition makes the targeted graphical code figure
Graphic code is unsatisfactory for the region of identification condition as target synthesis region as in.
A width graphic code image can be arbitrarily determined from the multiple image obtained as targeted graphical code image；Or
It is to determine the image of bad point area minimum as graphic code image；Can also be, it before can not to obtain several graphic code images
The image in 2 D code of identification does not limit in the embodiment of the present application as targeted graphical code image.
In targeted graphical code image, the region for making graphic code in the targeted graphical code image be unsatisfactory for identification condition is obtained
Region is synthesized as target.The concrete mode for obtaining target synthesis region does not limit in the embodiment of the present application, such as passes through side
The image processing methods such as edge detection are realized.
In the embodiment of the present application, Ke Yishi, it is not correct graphic code figure that target, which synthesizes figure in region, to make
Determining graphic code image None- identified, when the corresponding graphic code in target synthesis region is correct graphic code figure, figure
Shape code is recognizable.
Wherein, the target synthesis region in targeted graphical code image can be the corresponding region of whole of bad point, such as Fig. 5 institutes
The dotted portion shown；The either corresponding region of part bad point, dotted portion as shown in FIG. 6.
For synthesizing region using the corresponding region of part bad point as target, as an implementation, if graphic code figure
There are multiple bad points as in, the corresponding region of bad point that can be using one of them or more than one synthesizes region as target.Its
In, the number of bad point can be when these bad points are correct graphic code figure, and graphic code is with regard to identifiable number.
For synthesizing region using the corresponding region of part bad point as target, as another embodiment, if graphic code
Only there are one bad point in image, and when the part in the bad point is if correct graphic code figure, graphic code just can recognize that, then may be used
To synthesize region using the corresponding region of part bad point as target.
Step S230：Acquisition is corresponding with target synthesis region from other graphic code images, makes the target figure
Graphic code in barcode image meets the region of identification condition, as targeted graphical code region.
Other graphic code images be obtain several graphic code images in, it is different from determining targeted graphical code image
Graphic code image.Targeted graphical code region can be region corresponding with target synthesis region position in graphic code.The target
Graphic code region can be that area size, shape, the identical region in position are synthesized with target, can also be to synthesize region than target
Area smaller, the corresponding region in position.In targeted graphical code region, including correct graphic code figure, it is such as all correct
Graphic code figure.Optionally, targeted graphical code region can also be the region that part is correct graphic code figure.When target figure
When graphic code in shape code region is replaced in target synthesis region, the graphic code in targeted graphical code image can be known
Not.
Specifically, this step may include：It is obtained respectively from other graphic code images and synthesizes region pair with the target
The region answered.If other graphic code images of certain width correspond to target synthesis region region in without correct graphic code figure, no
It can be used for identifying graphic code, therefore, whether region corresponding with target synthesis region in other each graphic code images of judgement
Including at least a part for graphic code.The graphic code image for being yes according to each judging result, acquisition make the targeted graphical code figure
Graphic code meets the region of identification condition as in.In the embodiment of the present application, judge in other each graphic code images with the mesh
It can be an optional step that whether the corresponding region in mark synthesis region, which includes at least a part of of graphic code, can not also be into
Row judges, but so that graphic code in the targeted graphical code image is met identification condition by other all graphic code image acquisitions
Region.
As an implementation, if in other graphic code images, it can obtain there are piece image and make targeted graphical
Graphic code in code image meets the region of identification condition, then targeted graphical code region can be obtained directly from the width image.
Region as shown in phantom in Figure 7, which is substituted into, can obtain the as shown in Figure 8 identification condition that meets behind target synthesis region in Fig. 5
Graphic code.
As another embodiment, targeted graphical code can be obtained respectively from several in other graphic code images
The part in region, each section are a graphic code subregion in targeted graphical code region, different graphic code subregion point
The different zones in target synthesis region are not corresponded to.Specifically, from several in other graphic code images, determine respectively with
The corresponding region in target synthesis region, and judge whether the corresponding region in the synthesis of the target in each image region includes at least
A part for graphic code.From the graphic code image that each judging result is yes region corresponding with target synthesis region, obtain respectively
Take the corresponding different graphic code subregion of included graphic code.Each graphic code subregion is synthesized into the target figure again
Shape code region.
By taking Fig. 9 as an example, three width image shown in Fig. 9 is as other graphic code images for obtaining targeted graphical code region, Fig. 9
It is region corresponding with target synthesis region shown in middle dotted line.In Fig. 9 preceding two width correspond to target synthesis region region in deposit
It in graphic code, and is not present in last width, is then corresponded in the region that target synthesizes region from preceding two images and determine graphic code
Subregion, such as the corresponding region of graphic code in dotted line frame in preceding two images, i.e., in dotted line frame in addition to the intersection with bad point A
Region.Graphic code subregion synthesis in preceding two images in Fig. 9 is obtained into targeted graphical code region, such as dotted line frame in Figure 10
Shown in targeted graphical code region.
It should be understood that in the embodiment of the present application, targeted graphical code region is obtained from other graphic code images, specifically
Acquisition modes do not limit.If from several in other graphic code images, the part in targeted graphical code region is obtained respectively,
The graphic code subregion size obtained in each image does not limit.Graphic code subregion can be the image in each image
In the region in middle corresponding target synthesis region, the corresponding region of all graphic codes or the corresponding region of part figure shape code.
It should be understood that if the target synthesis region in targeted graphical code image is the corresponding region of part bad point, true
Behind fixed target synthesis region, if being unable to get the targeted graphical code region of the condition of satisfaction in other images, it can weigh
It is new to determine that the different piece of corresponding bad point synthesizes region as target.
Step S240：The target is replaced with targeted graphical code region and synthesizes region, and acquisition includes meeting identification item
The targeted graphical code image of the graphic code of part.
Target is replaced into targeted graphical code region and synthesizes region, keeps graphic code in targeted graphical code image recognizable.
For example, the targeted graphical code region as shown in Figure 10 obtained according to Fig.9, as shown in Figure 5 for replacing
After target synthesizes region, targeted graphical code image as shown in Figure 8 is obtained.
Can also be with each sub-regions point in addition, if targeted graphical code image includes multiple targeted graphical numeral region
Not Ti Huan target synthesis region in corresponding region.
It will of course be understood that, if as previously mentioned, graphic code has certain serious forgiveness, i.e. identification condition is that can not read
The graphic code information got accounts for serious forgiveness of the ratio less than the graphic code of the graphic code total information and the graphic code
In the quantity of position sensing figure that may be read into be more than preset quantity, then replace the target synthesis in targeted graphical code region
Behind region, it is also likely to be present bad point in targeted graphical code image, but has met identification condition.As dotted line frame indicates in Fig. 6
Target synthesis region be replaced after, obtain there is also the targeted graphical code image of bad point A is as shown in figure 11.
Step S250：Graphic code identification is carried out to the targeted graphical code image.
It identifies the graphic code in targeted graphical code image, obtains the content that the graphic code is included.
Optionally, several graphic code images of acquisition and the targeted graphical code image of synthesis can be stored, and such as be deposited
