Information processing method provided in an embodiment of the present invention is applied in an electronic equipment, is equipped with two on the electronic equipment
Tie up code decoding software.The electronic equipment may is that smart phone, smartwatch, tablet computer, Intelligent bracelet, intelligent glasses etc..
Two dimensional code decoding software be can to the software that two dimensional code is identified, such as: in the application programs such as wechat, Taobao, Meituan
" sweep and sweep ".
In a step 11, in the decoded information for needing to know two dimensional code, two dimensional code identification software is run on electronic equipment,
After two dimensional code identification software is run, the image acquisition units of electronic equipment can be opened, in this way, image acquisition units can be adopted persistently
Collect multiple image, multiple image forms video flowing, some possible images have two dimensional code in multiple image, some images are without two
Tie up code.Every frame image in video flowing is detected frame by frame using two dimensional code identification software, until detecting a frame image (hereinafter referred to as
First image) in have two dimensional code.
In step 12, after having two dimensional code in determining the first image, multiple pixels of the first image are analyzed,
The pixel of composition two dimensional code is extracted, then determines the frame that the pixel of all composition two dimensional codes in the first image is formed,
The region that frame is covered is exactly position of the two dimensional code in the first image.Then the position according to two dimensional code in the first image
It sets, determines that the image acquisition units of electronic equipment acquire the first visual angle of the first image, and then be determined for compliance with the aobvious of the first visual angle
Show mode (hereinafter referred to as the first display mode), finally shows the decoded information of two dimensional code in the first figure with the first display mode
As in.
Wherein, the position according to two dimensional code in the first image determines the image acquisition units acquisition first of electronic equipment
The process at the first visual angle of image are as follows: usual two dimensional code to be identified is in source images, the then Image Acquisition list of electronic equipment
Member carries out continuous collecting to source images, and then collects multiple image.Therefore, from the pixel of the two dimensional code in composition source images
It is middle to select multiple pixels as multiple anchor points, determine multiple anchor points in the position of source images and multiple anchor points
Then position in one image determines same anchor point respectively in the position in source images and between the position in the first image
Line, determine a plurality of line in a similar way, then calculate the angle of a plurality of line and the plane where source images, folder
Angle can react the first visual angle.
It is determined for compliance with the process of the display mode (i.e. the first display mode) at the first visual angle are as follows: since the first visual angle is electronics
The image acquisition units of equipment acquire the visual angle of the first image, and the image acquisition units of electronic equipment are the use by electronic equipment
What family was held, so, the first visual angle embodies the visual angle that user watches the first image.Under normal conditions, the decoding figure of two dimensional code
The display mode of picture is fixed and invariable, in order to improve the visual experience of user, according to the first visual angle, it is determined whether need to two
The decoding image of dimension code is distorted and is stretched, to form the first display mode.
In step 13, judge whether two dimensional code is located in the second image different from the first image, that is, is detecting
After having two dimensional code in one image, whether there is the two dimensional code in the multiple image after the first image of detection.Step 13 includes:
At least one angle point of the two dimensional code is tracked, tracking result, the tracking result characterization described at least one are obtained
It is located at the quantity of the angle point in second image in a angle point；
Judge whether there is predetermined quantity angle point to be located in second image at least one described angle point.
Specifically, due to having two dimensional code in the first image, it is possible to determine all composition two dimensional codes in the first image
The frame that is formed of pixel, determine that at least one angle point, angle point are to form two dimensional code out of frame is covered region
The pixel of the decoded information of two dimensional code is carried in pixel.Then track whether at least one angle point is located in the second image,
And how many angle point is located in the second image at least one angle point, if the quantity for the angle point being located in the second image is big
In predetermined quantity, then the two dimensional code is located in the second image, otherwise, two dimensional code is not present in the second image.Predetermined quantity can be with
It is user setting, is also possible to the setting of two dimensional code identification software.
As it can be seen that two dimensional code identification process is detected independent of two dimensional code in the embodiment of the present invention, and can be tied according to tracking
Fruit calculates, therefore still can successfully identify two dimensional code at big visual angle.Improve the success rate of identification two dimensional code.
At step 14, when two dimensional code is located in the second image, image acquisition units acquire the second image the is obtained
Two visual angles.Because the image acquisition units of electronic equipment are usually to be held by user, as the visual angle of user becomes
Change, the visual angle of the collected different images of image acquisition units also changes, such as visual angle when acquiring the first image is the
One visual angle, visual angle when acquiring the second image are the second visual angle.
Step 14 includes:
When there is predetermined quantity angle point to be located in second image at least one described angle point, according to described predetermined
Position of the quantity angle point in second image determines position of the two dimensional code in second image；
According to position of the two dimensional code in second image, second visual angle is determined.
Specifically, when there is predetermined quantity angle point to be located in the second image at least one angle point, two dimensional code is located at
In second image.Since the two dimensional code in the second image is identical as the two dimensional code in the first image, according to two in the first image
Code is tieed up, position of the predetermined quantity angle point in the first image in the second image can be determined, can also determine the first image
The position of other pixels in all pixels point of middle composition two dimensional code in addition to predetermined quantity angle point, and then determine composition two
Other pixels in all pixels point of code in addition to predetermined quantity angle point are tieed up relative to the opposite of predetermined quantity pixel
Position.In this way, in the position according to predetermined quantity pixel in the second image, and all pixels point of composition two dimensional code
Relative position of other pixels relative to predetermined quantity pixel in addition to predetermined quantity angle point, can determine composition two
Position of other pixels in the second image in all pixels point of code in addition to predetermined quantity angle point is tieed up, in this way, just really
Position of the two dimensional code in the second image is determined.
Finally, the position according to two dimensional code in the second image, determines the second visual angle, with according to two dimensional code in the first image
In position, determine that the first visual angle is similar, details are not described herein again.
It is high to the tracking computational efficiency of appropriate angle point in the embodiment of the present invention, and according to a large amount of angle points position in the track
The position of two dimensional code extrapolated of variation it is more accurate, so that the decoded information of two dimensional code is also more nearly true visual angle.
In step 15, it according to the relationship at the first visual angle and the second visual angle, determines the second display mode, is then shown first
The mode of showing is adjusted to the second display mode, finally in a second display mode in the second image two-dimensional code display decoded information.
The relationship based on first visual angle Yu second visual angle in step 15, adjusting first display mode is the second display
Mode, comprising:
Obtaining the position of at least one angle point in the first image under first visual angle is first position；
Obtaining the position of at least one angle point in second image under second visual angle is the second position；
According to the difference between the first position and the second position, adjusting first display mode is second aobvious
Show mode.
Specifically, since the second image is different from the first image, so at least one angle point of two dimensional code is in the second figure
Position as in is different from position of the two dimensional code in the first image.Position of at least one angle point of two dimensional code in the first image
Be set to first position, due to the first image be electronic equipment image acquisition units it is collected under the first visual angle, so two
Tie up the first visual angle of position reaction of at least one angle point of code in the first image, similarly, at least one angle point of two dimensional code
Position in the first image is the second position, since the second image is the image acquisition units of electronic equipment under the second visual angle
It is collected, so the second visual angle of position reaction of at least one angle point of two dimensional code in the second image.
According to the difference of first position and the second position, the difference at the first visual angle Yu the second visual angle, Jin Ergen can determine
According to the difference at the first visual angle and the second visual angle, the display mode of the decoding image of two dimensional code is adjusted, such as: the decoding to two dimensional code
Image is stretched or is distorted, and then is adjusted to the second display mode from the first display mode.
The decoded information for showing the two dimensional code in second image with second display mode in step 15,
Include:
Determine the frame of two dimensional code described in second image；
Determine the angle of the decoded information of the two dimensional code under second visual angle；
The decoded information of the two dimensional code is shown in the region of frame covering in the second image with the angle.
Specifically, due to having two dimensional code in the second image, it is possible to determine all composition two dimensional codes in the second image
The frame that is formed of pixel, the as frame of two dimensional code.Since the image acquisition units that the second visual angle is electronic equipment acquire
The visual angle of second image, and the image acquisition units of electronic equipment be held by the user of electronic equipment, so, the second visual angle
Embody the visual angle that user watches the second image.In order to enable the angles of display of the decoded information of two dimensional code meets user's viewing the
The visual angle of two images can determine the angular field of view of user according to the second visual angle, then by the angle of the decoded information of two dimensional code
It determines in the angular field of view of user, finally the angle two-dimensional code display in the coverage area of the frame of two dimensional code to determine
Decoded information.In this way, without transformation angle when user checks the decoded information of two dimensional code.
For example, the decoded information of two dimensional code is stereo-picture, it is also possible to non-cubic image.With the decoding of two dimensional code
For information is stereo-picture, according to the second visual angle, the angular field of view of user is determined, it is then that the angle presentation of stereo-picture is true
It is scheduled in the angular field of view of user, in this way, user can check stereo-picture under the second visual angle, is not necessarily to transformation angle.
Certainly, the decoding letter for showing the two dimensional code in the first image with the first display mode in step 12
Breath, with the decoded information class for showing the two dimensional code in second image with second display mode in step 15
Seemingly, it is just not explained in detail herein.

Compare the testing result and the tracking result, determines the error of the tracking result；
When the error is less than preset range, executes step: tracking at least one angle point of the two dimensional code.
Specifically, after detecting that two dimensional code is located in a frame image, every predetermined number of frames image, two dimensional code is detected
Whether it is located at and is separated by a frame image of predetermined number of frames image with the frame image, is separated by if two dimensional code is located at the frame image
In one frame image of predetermined number of frames image, then illustrate that tracking quality is good, at least one angle for tracking two dimensional code can be continued

4) two-dimentional code position in current frame video image is estimated according to tracking result, if the figure on current two-dimension position
Picture is similar to two dimensional code, then judges whether current frame video image needs intermittent detection；
Whether 5) if current frame video image needs intermittent detection, detecting in current frame video image has two dimension
Code；
If 6) detect there is two dimensional code in current frame video image, judge tracking result and testing result whether one
It causes；
7) if detecting in current frame video image does not have two dimensional code or current frame video image not to need intermittence
