Specific embodiment
Purpose, technical scheme and advantage for making the disclosure become more apparent, with reference to embodiment and accompanying drawing, right
The disclosure is described in further details.Here, the exemplary embodiment of the disclosure and its illustrate for explaining the disclosure, but simultaneously
Not as restriction of this disclosure.
The embodiment of the present disclosure provides a kind of method of screen printing picture, device and terminal unit, below in conjunction with accompanying drawing pair
The disclosure is described in detail.
In the embodiment of the present disclosure one, as shown in figure 1, a kind of method of screen printing picture includes：
In step S101, after monitoring screenshotss operation, obtain all screenshot picture in scheduled duration, the present embodiment
Method is used in terminal unit.
Screenshotss operate as user input for intercepting the operation of current full screen image.This screenshots operation can be to cut
The click of screen button, or other gesture operation for screenshotss.After terminal receives screenshotss operational order, intercept current full screen
Image is simultaneously preserved with graphic form（Temporal cache can be adopted）.When monitoring screenshotss operation first, start intervalometer, and continue
Continuous monitoring screenshotss operation.In timer expiry, stop monitoring screenshotss operation.If monitoring within this period of intervalometer timing
To the operation of multiple screenshotss, that is, obtain multiple screenshot picture, then continue below step.
For example, the scheduled duration of intervalometer is 1 minute, monitors the operation of 3 screenshotss altogether it is determined that this 3 times in 1 minute
Screenshotss operation content degree of association higher it may be necessary to carry out the splicing of screenshot picture.
In timer expiry, intervalometer stops timing, and timing is reset.If monitoring again, screenshotss operate, really
Determine this time to monitor for monitoring screenshotss operation first, and restart intervalometer.Screenshotss operation twice can also be detected by intervalometer
Between time, if twice screenshotss operation between time be less than preset duration then it is assumed that this twice screenshotss operate in content
Upper correlation is it may be necessary to carry out the splicing of screenshot picture；If the time between screenshotss operation twice is more than or equal to default
Length then it is assumed that this screenshotss operation twice does not have dependency in terms of content, do not enter by the screenshot picture that this screenshotss operation twice obtains
Row splicing.
For the multiple screenshotss operation in scheduled duration, obtain all screenshot picture that each screenshotss operation generates.
In step s 102, detect when there is the screenshot picture that there is public territory in all screenshot picture, will have
The public territory lap splice that there is the screenshot picture of public territory is pictures.
Public territory refers to content identical part between each screenshot picture, has between the screenshot picture of public territory
Generally there is seriality in terms of content, picture can be carried out and splice to form complete content.If between multiple screenshot picture
There is no public territory it is determined that there is no seriality in terms of content between multiple screenshot picture, screenshot picture can not be carried out
Splicing.
According to the sequence detection intercepting, public territory be whether there is to all screenshot picture.For example there are 3 screenshot picture,
Screenshot picture 1, screenshot picture 2 and screenshot picture 3, first detecting according to the order intercepting between screenshot picture 1 and screenshot picture 2 is
No have public territory, then detects between screenshot picture 1 and screenshot picture 3 with the presence or absence of public territory, then detects snapshot
Whether there is public territory between piece 2 and 3.If detect there is the screenshot picture that there is public territory it is determined that these are deposited
Picture in public territory can be spliced.In all screenshot picture obtaining, for any other screenshot picture all
There is not the screenshot picture of public territory it is not necessary to carry out image mosaic, can directly be deleted.
Detect when there is the screenshot picture that there is public territory in all screenshot picture there is cutting of public territory by having
The public territory lap splice of screen picture is pictures.
As Fig. 2（a）With Fig. 2（b）Shown, two width figures are that screenshotss operate the screenshot picture that gained falls twice, Fig. 2 is detected
（a）With Fig. 2（b）Between there is public territory, public territory such as Fig. 2（c）Shown then it is assumed that Fig. 2（a）And Fig. 2（b）Can splice
For pictures, Fig. 2（a）With Fig. 2（b）The picture such as Fig. 2 being formed after splicing（d）Shown.
By have public territory screenshot picture lap splice be pictures, comprise the following steps as shown in Figure 3：
In step S301, pretreatment is carried out to the screenshot picture that there is public territory.
Pretreatment includes removing the noise in screenshot picture and correcting image distortion.Mean filter or intermediate value can be passed through
The mode of filtering removes noise；Corresponding mathematical model is set up, from contaminated or distortion picture intelligence during correcting image distortion
Information required for middle extraction, recovers image style along the inverse process making image distortion.
In step s 302, image registration is carried out to the pretreated screenshot picture that there is public territory.
Image registration is in image not in the same time, more than two width that photograph of different points of view, different cameral or two width
Carry out alignment spatially.Match information in the image of the screenshot picture with public territory is extracted, is extracting
Information in find optimal coupling, complete the alignment between image.For example can be compared one by one by the registration Algorithm based on region
Method, layering relative method or phase correlation method etc. carry out image registration；Can also be by the registration Algorithm of feature based, such as chi
Degree invariant features become scaling method, ratio matching method etc. and carry out image registration.
In step S303, image reprojection is carried out to the screenshot picture of the presence public territory after registration.
For needing the screenshot picture with public territory spliced after registration, by the figure of wherein one width screenshot picture
As reference picture, then other images being carried out torsional deformation and going to the coordinate system of reference picture, so will own
Image projection under the same coordinate system, complete a projective transformation.
In step s 304, image co-registration is carried out to the screenshot picture that there is public territory.
After the registration completing two width images, and the transformation matrix between two width images is obtained by reprojection, just
Can determine the overlapping region between them, the task of image co-registration be exactly registration after two width images according to registering position
Merge into piece image.Under conditions of image rigid registrations, two width images to be spliced are directly carried out with pixel association and merges
Process；Adoptable method includes：Mean value method, weighted mean method, median filtering method, multi-level technique etc..
Embodiment of the disclosure one, all screenshotss operations in the detection scheduled time, whether automatic decision screenshot picture deposits
In public territory, the screenshot picture that there will be public territory is spliced into pictures, thus will intercept several times beyond screen
The picture of height is spliced into a picture not having redundancy, is easy to user and is shared picture.
During upper and lower browsing pages content, some contents on screen interface are fixed to user, such as Fig. 2
（a）Top tape have the Information of time and bottom to carry the menu bar of information such as " forwardings ".For multiple screenshot picture, all
Including these fixed contents, these contents and Fig. 2（c）Shown content is different, is not belonging to public territory, and the disclosure is real
Apply in example by this partly fixed content be referred to as identical edge frame.In the splicing carrying out screenshot picture, phase
Same edge frame is to need to delete, and otherwise affects splicing effect.The process of implementing refers to the following examples.
In the embodiment of the present disclosure two, as shown in figure 4, a kind of method of screen printing picture includes：
In step S401, after monitoring screenshotss operation, obtain all screenshot picture in scheduled duration, the present embodiment
Method is used in terminal unit.Realize with S101 that process is identical, here does not do repeat specification.
In step S402, when at least two screenshot picture is detected there is identical edge frame, puncture edge
Framework.
Whether all screenshot picture that detection obtains have identical edge frame.When edge frame refers to screenshotss operation,
Application interface outside Web page picture content or system interface, such as Fig. 2（a）And Fig. 2（b）" the microblogging text " at middle top
Part and " forward, comment on, praising " part of bottom, above-mentioned partly belong to specific application interface, in each screenshot picture
All exist, therefore in order to ensure picture splicing effect, before carrying out picture splicing, need phase this in each screenshot picture
Same edge frame punctures.
The method that in all screenshot picture that detection intercepts, whether at least two screenshot picture have identical edge frame
As shown in figure 5, comprising the following steps：
In step S501, each screenshot picture in all screenshot picture is grouped with two for one group, side by side
Enumerate all packet modes.In order to detect the edge frame occurring in all screenshot picture it is ensured that splicing effect, by all sections
Screen picture is pairwise grouping, and includes all packet modes, to detect that all screenshot picture whether there is between any two
Identical edge frame.
In step S502, whether detection each two screenshot picture has identical edge frame one by one.
For all packet modes including in step S501, detect that two screenshot picture in each packet are one by one
No have identical edge frame.
In step S503, obtain the pixel difference of the pixel of same position in each screenshot picture in same packet respectively
The absolute value of value, and scanned picture is constituted according to the absolute value of the pixel value difference of all pixels point.
In step S504, scanned picture is scanned, when the absolute value of the pixel value difference in scan line is not more than in advance
If threshold value, then judge that the corresponding pixel of absolute value of pixel value difference is located in edge frame；When the pixel value difference in scan line
Absolute value be more than predetermined threshold value, then judge pixel value difference the corresponding pixel of absolute value be located at edge frame outside.
Start to do transversal scanning to the inside of scanned picture from the bottom margin of scanned picture and top, simultaneously from scanning
The left side edge of picture and right side edge start to do longitudinal scanning to the inside of scanned picture, to detect whether edge has phase
Same edge frame.
If one in scan line pixel value difference absolute value be less than or equal to predetermined threshold value, judge scan line on each
The corresponding pixel of absolute value of pixel value difference is located in edge frame, and proceeds in the corresponding direction to scan.If
Article one, in scan line, the absolute value of pixel value difference is more than predetermined threshold value, then judge the absolute value corresponding pixel position of pixel value difference
Outside edge frame.
Article one, in scan line pixel value difference absolute value be more than predetermined threshold value when it may be possible to due to this pixel value difference correspond to
The image fault of pixel cause, therefore when absolute value pixel value difference in scan line is more than predetermined threshold value
During situation, whether the absolute value that can calculate the sum of all pixels difference in a scan line further is more than another default threshold
Value, if the absolute value of the sum of all pixels difference is more than another predetermined threshold value in a scan line, judges in scan line
The corresponding pixel of absolute value of each pixel value difference is located at outside edge frame, if all pixels difference in a scan line
The absolute value of sum is less than or equal to another predetermined threshold value, then judge the corresponding picture of absolute value of each pixel value difference in scan line
Vegetarian refreshments is located within edge frame.
When at least two screenshot picture is detected there is identical edge frame, then puncture identical edge frame.Protect
Stay the internal real Web page picture content of screenshot picture, make to there is not edge frame in spliced picture it is ensured that spliced
The seriality of image content.
