Based on above-mentioned mobile terminal hardware configuration and communications network system, each embodiment of the method for the present invention is proposed.
Embodiment one
As shown in figure 3, the embodiment of the present invention one proposes a kind of method that intelligence calls front camera and rear camera imaging, this method base
In the terminal for being less than preset threshold with the pixel difference between front camera and rear camera and front camera and rear camera, following step is specifically included
It is rapid:
Step S110: after receiving the pan-shot instruction that user issues, into panorama photographing mode, and simultaneously by proactive
The first image information is obtained as head and the second image information is obtained by rear camera.
Specifically, currently, most mobile terminal all has former and later two cameras on the market, the two division of labor is clear,
It does not interfere with each other.In general, preceding camera more pays close attention to portrait, and it is most of all to have beauty Yan Gongneng, it is taken pictures using preceding camera
When scenery processing it is poor；Rear camera pixel is slightly higher, and function is relatively more, visual angle is bigger, imaging total quality is relatively former
Object did not did multiprocessing to portrait and scenery.Since the pixel of former and later two cameras is different, front and back is called to take the photograph to intelligence
As head progress panoramic imagery, need to the acquisition parameters of former and later two cameras be carried out with some adjustment, and for former and later two camera shootings
The difference of the pixel of head is different, and practical method of adjustment also has some differences, at this point, the ginseng of a preset threshold need to be introduced
Number, judges come the difference of the pixel of former and later two cameras to terminal, to judge which kind of present terminal adjust suitable for
Means are required according to practical Adjustment precision, and the numerical value of the preset threshold can carry out practical adjustment, if Adjustment precision is more demanding,
Then the numerical value of the preset threshold is smaller, and image quality is higher at this time, if Adjustment precision requires lower, the numerical value of the preset threshold
Larger, image quality is lower at this time.
The embodiment of the present invention is default mainly for being less than with the pixel difference between front camera and rear camera and front camera and rear camera
The terminal of threshold value into panorama photographing mode, and passes through proactive picture after receiving the pan-shot instruction that user issues simultaneously
Head obtains the first image information and obtains the second image information by rear camera.
Pan-shot instruction, which specifically includes full-view image shooting instruction and distant view photograph shooting instruction, i.e. user, can both lead to
It crosses calling front camera and rear camera and completes full-view image shooting, can also be shot by calling front camera and rear camera to complete distant view photograph, due to
There is terminal the pixel difference between front camera and rear camera and front camera and rear camera to be less than preset threshold, i.e., takes the photograph before and after expression terminal
As head pixel difference is little, the first image information for being acquired by preceding camera with acquired by rear camera the
Two image informations, the two screen resolution difference is not too much more, is automatically adjusted without early period to camera pixel, after only needing
Phase by preceding camera obtain the first image information and by rear camera obtain the second image information after, by terminal oneself
For band picture optimization algorithm to its voluntarily adjust automatically, the resolution parameter for the image information that both can make keeps one
It causes.
Step S120: the resolution parameter of adjust automatically first image information and the resolution ratio of second image information are joined
Number, it is ensured that the resolution parameter of first image information and the resolution parameter of second image information are consistent.
Specifically, since the method that the intelligence of the embodiment of the present invention calls front camera and rear camera imaging is intended to through intelligent calling
Before the picture of front camera and rear camera shooting is automatically synthesized panorama, and the different image information of two width synthesizes a width panorama
The condition of mentioning is that the resolution ratio of two width image informations will be consistent, thus, after receiving the pan-shot instruction that user issues,
Into panorama photographing mode, and obtains the first image information by preceding camera simultaneously and obtain second by rear camera and draw
After the information of face, just need at once by terminal carry picture optimization algorithm adjust automatically first image information resolution parameter with
The resolution parameter of second image information, to ensure the resolution parameter and second image information of first image information
Resolution parameter is consistent.Since the resolution parameter that the camera of high pixel shoots the image information come can compare low pixel
Camera shoot the high resolution of the image information come, and the resolution ratio of image information only just can ensure that original toward low-key is whole
Image information will not be distorted, thus, when execute this step " resolution parameter of adjust automatically first image information and this second
The resolution parameter of image information, it is ensured that the resolution ratio of the resolution parameter of first image information and second image information is joined
Number be consistent " when, as shown in figure 4, its detailed process is as follows:
Step S121: if the resolution ratio of first image information is greater than the resolution ratio of second image information, by this
The resolution adjustment of one image information is the resolution ratio of second image information.
Step S122: if the resolution ratio of second image information is greater than the resolution ratio of first image information, by this
The resolution adjustment of two image informations is the resolution ratio of first image information.
So, adjust automatically in this way, can make first image information resolution parameter and this
The resolution parameter of two image informations is consistent, and realizes that the premise of synthesis panorama prepares.
Step S130: panorama is synthesized with second image information according to first image information adjusted.
Specifically, when adjust automatically through the above steps so that the resolution parameter of first image information and this
After the resolution parameter of two image informations is consistent, it can be believed according to first image information adjusted and second picture
Breath synthesis panorama.Detailed process is as follows: first image information adjusted and second image information are carried out image
Panorama is synthesized after matching treatment, image mosaic processing, image co-registration processing and panoramic picture projection processing.
Wherein, images match processing refers mainly to match pass according between estimation picture in part overlapped in rope material picture
System.Main matching way is divided to two kinds: the A. matching way unrelated with feature.Most common is relevant matches.B. according to spy
Sign carries out matched mode.It is most common i.e. for according to SIFT, local feature region in the tables material picture such as SURF matches adjacent picture
In characteristic point, estimate image between projective transformation matrix.Image mosaic processing refers mainly to handle resulting figure according to images match
Piece correlation, adjacent picture is stitched together.Image co-registration processing refers mainly to merge the panorama sketch that splicing obtains
Processing, panoramic picture projection processing refer mainly to for the panorama sketch after synthesis being projected on spherical surface, cylinder or cube and establish conjunction
Suitable viewpoint realizes comprehensive views browsing.After the processing of this several step, panorama can be synthesized, realizes panorama shadow
As shooting or distant view photograph shooting.
In addition, panorama specifically refers to be capable of providing parallactic angle 360 above horizontal direction in a fixed point of observation
Degree, 180 degree is free to navigate through (simplified panorama can only provide 360 degree of horizontal direction of browsing) in vertical direction, and due to
Inventive embodiments are to carry out pan-shot by calling front camera and rear camera, and the first image information of preceding camera shooting is at most only
The second image information including front 180 degree Viewing-angle information, and rear camera shooting at most only includes rear 180 degree visual angle letter
Breath, so, what this intelligence called the method shooting of front camera and rear camera imaging is simplified panorama, can only provide horizontal direction 360
The browsing of degree.
The method of front camera and rear camera imaging is called by this intelligence, it can be achieved that taking the photograph grabbed picture merging with after for proactive
It is shown for a picture.People's bat scape is clapped when taking pictures to neglect neither, and there can be more objects to simultaneously participate in (phase when shooting video
The function of machine is constant, and defaulting open is still traditional camera, this mode camera mode new as one need to be opened manually).
For taking pictures and possessing more shooting enjoyment for shutterbugs, at the same time it can also apply to multiple fields, such as: driving
(similar devices such as automobile data recorder on the market all use the design of single camera to recorder, can only record institute in front of driver
There is a situation where, when emergency occurring on vehicle or when traffic accident will occur, measure that driver is taken other people can not
Know, to influence judgement to accident responsibility, and utilize this method, then can record the detailed process that accident occurs), reversing shadow
A variety of capture apparatus such as picture, monitoring.
Embodiment two
As shown in figure 5, the embodiment of the present invention one proposes a kind of method that intelligence calls front camera and rear camera imaging, this method base
In the terminal for being equal to or more than preset threshold with the pixel difference between front camera and rear camera and front camera and rear camera, specifically include
Following steps:
Step S210: after receiving the pan-shot instruction that user issues, into panorama photographing mode, and adjust automatically is proactive
As the pixel-parameters of head and the pixel-parameters of rear camera, it is ensured that the pixel-parameters of the preceding camera and the pixel of the rear camera
Parameter is consistent.
Specifically, currently, most mobile terminal all has former and later two cameras on the market, the two division of labor is clear,
It does not interfere with each other.In general, preceding camera more pays close attention to portrait, and it is most of all to have beauty Yan Gongneng, it is taken pictures using preceding camera
When scenery processing it is poor；Rear camera pixel is slightly higher, and function is relatively more, visual angle is bigger, imaging total quality is relatively former
Object did not did multiprocessing to portrait and scenery.Since the pixel of former and later two cameras is different, front and back is called to take the photograph to intelligence
As head progress panoramic imagery, need to the acquisition parameters of former and later two cameras be carried out with some adjustment, and for former and later two camera shootings
The difference of the pixel of head is different, and practical method of adjustment also has some differences, at this point, the ginseng of a preset threshold need to be introduced
Number, judges come the difference of the pixel of former and later two cameras to terminal, to judge which kind of present terminal adjust suitable for
Means are required according to practical Adjustment precision, and the numerical value of the preset threshold can carry out practical adjustment, if Adjustment precision is more demanding,
Then the numerical value of the preset threshold is smaller, and image quality is higher at this time, if Adjustment precision requires lower, the numerical value of the preset threshold
Larger, image quality is lower at this time.
The embodiment of the present invention is greater than or waits mainly for the pixel difference between front camera and rear camera and front camera and rear camera
In the terminal of preset threshold, after receiving the pan-shot instruction that user issues, into panorama photographing mode, and adjust automatically
The pixel-parameters of preceding camera and the pixel-parameters of rear camera, it is ensured that the pixel-parameters of the preceding camera and the rear camera
Pixel-parameters are consistent.
Pan-shot instruction, which specifically includes full-view image shooting instruction and distant view photograph shooting instruction, i.e. user, can both lead to
It crosses calling front camera and rear camera and completes full-view image shooting, can also be shot by calling front camera and rear camera to complete distant view photograph, due to
There is terminal the pixel difference between front camera and rear camera and front camera and rear camera to be greater than or equal to preset threshold, that is, indicate terminal
Front camera and rear camera pixel difference is bigger, at this point, the first image information acquired by preceding camera with pass through after image
The second image information that head acquires, the two screen resolution is larger, is not suitable for adjusting the resolution of image information using the later period
The method of rate parameter can only be automatically adjusted the pixel of front camera and rear camera, to pass through the picture for ensuring the preceding camera early period
In the case of the pixel-parameters of plain parameter and the rear camera are consistent, it is ensured that the later period obtains the first picture by preceding camera
Information and by rear camera obtain the second image information after, the resolution parameter of the image information of the two is consistent.
Since the resolution parameter that the camera of high pixel shoots the image information come can be clapped than the camera of low pixel
The high resolution of the image information come is taken out, and when the pixel of two cameras difference is larger, come to ensure that the two is shot
Image information resolution ratio, can only first adjust the pixel-parameters of two cameras early period, due to camera maximum pixel only
It can be determined by itself physical characteristic, thus, the pixel of camera can only just can ensure that the pixel of the preceding camera toward low adjustment
In the case of the pixel-parameters of parameter and the rear camera are consistent, it is ensured that the later period obtains the first picture by preceding camera and believes
After ceasing and obtaining the second image information by rear camera, the resolution parameter of the image information of the two is consistent.Such as Fig. 6
Shown, detailed process is as follows:
Step S211: if the pixel of the preceding camera is greater than the pixel of the rear camera, by the pixel of the preceding camera
It is adjusted to the pixel of the rear camera.
Step S212: if the pixel of the rear camera is greater than the pixel of the preceding camera, by the pixel of the rear camera
It is adjusted to the pixel of the preceding camera.
So, adjust automatically in this way, can be in the pixel-parameters and the rear camera shooting for ensuring the preceding camera
In the case of the pixel-parameters of head are consistent, it is ensured that the later period takes the photograph by preceding camera the first image information of acquisition and after passing through
After obtaining the second image information as head, the resolution parameter of the image information of the two is consistent, and realizes synthesis panorama
Premise prepares.
Step S220: while the first image information is obtained by the preceding camera and obtains second by the rear camera
Image information.
Specifically, since the method that the intelligence of the embodiment of the present invention calls front camera and rear camera imaging is intended to through intelligent calling
Before the picture of front camera and rear camera shooting is automatically synthesized panorama, and the different image information of two width synthesizes a width panorama
The condition of mentioning is that the resolution ratio of two width image informations will be consistent, thus, after receiving the pan-shot instruction that user issues,
Into panorama photographing mode, and the pixel-parameters of the pixel-parameters of adjust automatically preceding camera and rear camera, it is ensured that this is proactive
After being consistent as the pixel-parameters of head and the pixel-parameters of the rear camera, at this point, only first need to be obtained by preceding camera
Image information and the second image information is obtained by rear camera, can ensure the resolution parameter of first image information with
The resolution parameter of second image information is consistent, and realizes that the premise of synthesis panorama prepares.
Step S230: panorama is synthesized with second image information according to first image information.
Specifically, when pixel adjust automatically through the above steps, consistent first picture letter of resolution parameter is obtained
Breath can synthesize panorama with second image information according to first image information with after second image information.Specifically
Process is as follows: first image information being carried out images match processing with second image information, image mosaic is handled, image melts
Panorama is synthesized after closing processing and panoramic picture projection processing.
Wherein, images match processing refers mainly to match pass according between estimation picture in part overlapped in rope material picture
System.Main matching way is divided to two kinds: the A. matching way unrelated with feature.Most common is relevant matches.B. according to spy
Sign carries out matched mode.It is most common i.e. for according to SIFT, local feature region in the tables material picture such as SURF matches adjacent picture
In characteristic point, estimate image between projective transformation matrix.Image mosaic processing refers mainly to handle resulting figure according to images match
Piece correlation, adjacent picture is stitched together.Image co-registration processing refers mainly to merge the panorama sketch that splicing obtains
Processing, panoramic picture projection processing refer mainly to for the panorama sketch after synthesis being projected on spherical surface, cylinder or cube and establish conjunction
Suitable viewpoint realizes comprehensive views browsing.After the processing of this several step, panorama can be synthesized, realizes panorama shadow
As shooting or distant view photograph shooting.
In addition, panorama specifically refers to be capable of providing parallactic angle 360 above horizontal direction in a fixed point of observation
Degree, 180 degree is free to navigate through (simplified panorama can only provide 360 degree of horizontal direction of browsing) in vertical direction, and due to
Inventive embodiments are to carry out pan-shot by calling front camera and rear camera, and the first image information of preceding camera shooting is at most only
