The embodiment of the invention provides a kind of shooting anti-fluttering method, as shown in Figure 1, comprising:
Step S101, obtain the image that the lens direction second camera opposite with the lens direction of the first camera gathers constantly in the shooting of the first camera photographic images.
The image that step S102, basis are obtained, needed primary importance variable parameter when determining to carry out the electronic flutter-proof processing.
Step S103, based on the primary importance variable parameter of determining, the image that the first camera is gathered constantly in this shootings carries out the electronic flutter-proof processing.
In the above-mentioned shooting anti-fluttering method, the first camera and second camera are two cameras that belong to same capture apparatus, and the lens direction of these two cameras is opposite, namely differ 180 degree, namely usually said forward direction camera and backward camera are in the embodiment of the present application, for the ease of description and the understanding of scheme, the camera of current responsible shooting in these two cameras is called the first camera, another camera is called second camera.
In the embodiment of the invention, when second camera shooting environmental of living in is better than the first camera shooting environmental of living in, for example, second camera is under the frontlighting environment, and the first camera is under the backlight environment, this moment, the definition of the image that second camera gathers will be greater than the definition of the image of the first camera collection, so according to the image of second camera collection determine carry out electronic flutter-proof when processing needed change in location parameter (for ease of distinguishing, follow-up this change in location parameter is called the primary importance variable parameter), with determine according to the image of the first camera collection carry out electronic flutter-proof when processing needed change in location parameter (for ease of distinguishing, follow-up this change in location parameter is called second place variable parameter) compare, to be more accurate, so, under this shooting environmental, based on the primary importance variable parameter the first camera is carried out electronic flutter-proof at the image of taking moment collection and process resulting anti-shake effect, to be better than based on second place variable parameter the first camera being carried out electronic flutter-proof and processing resulting anti-shake effect taking the image that constantly gathers, namely know that through the image of shooting of anti-shake processing degree is higher.
Below in conjunction with accompanying drawing, with specific embodiment method provided by the invention and device are described in detail.
Embodiment 1:
The flow chart of the shooting anti-fluttering method that provides in the embodiment of the invention 1 is provided, specifically comprises following treatment step:
Step S201, after opening employed the first camera of current shooting, the first camera is with real-time image acquisition, and buffer memory.Capture apparatus under the first camera then obtains the image of the first camera collection, specifically can be periodically to obtain the current latest image that gathers, and the cycle of obtaining can be determined according to attribute, use experience and the actual needs of camera.
Step S202, judge the first camera collection the definition of image whether less than setting clarity threshold, if so, enter step S203 otherwise, enter step S207.
Owing to be subject to the impact of light in the current shooting equipment shooting environmental of living in, the definition of the image of camera collection will change, for example more weak at light intensity, perhaps the first camera is under the environment of backlight, with so that the definition of the image of the first camera collection is lower; And light intensity is more intense, and perhaps the first camera is under the environment of frontlighting, and the definition of the image that then gathers is higher.
Step S203, unlatching second camera, second camera real-time image acquisition, and buffer memory.This capture apparatus then obtains the image that second camera gathers, and specifically can be periodically to obtain the current latest image that gathers, and the cycle of obtaining can be determined according to attribute, use experience and the actual needs of camera.
Step S204, judge the image that second camera gathers definition whether less than setting clarity threshold, if not, enter step S205 otherwise, enter step S207.
This moment is if because light intensity causes a little less than the definition of image of the first camera collection lower, less than setting clarity threshold, then the definition of the image of second camera collection also may be lower, namely also set clarity threshold less than this, and if since the first camera be in the backlight environment and cause the definition of image of the first camera collection lower, then because the lens direction of second camera and the first camera differs 180 degree, so this moment, second camera necessarily was in the frontlighting environment, then the definition of the image of second camera collection may be higher, namely set clarity threshold greater than this.
Step S205, when the first camera carries out image taking, the image that constantly gathers in the shooting of the first camera photographic images according to second camera, needed primary importance variable parameter when determining to carry out the electronic flutter-proof processing, determine the image of primary importance variable parameter institute basis in this step, be the image that in the process that the first camera is taken, gathers, and it is identical to gather moment of image in the moment that gathers image and the process that the first camera is taken.
The concrete of change in location parameter determines that method can adopt the scheme in the existing electronic flutter-proof technology, no longer be described in detail at this, but for the ease of the understanding of scheme, the principles illustrated of electronic flutter-proof technology is as follows:
Because near big and far smaller visual imaging theory and the image-forming principle of convex lens, when in the shooting process during capture apparatus generation translation, larger from object the displacement in real image of camera lens close to more, less from object the displacement in real image of camera lens away from more, to the object of infinity then displacement be 0.So, can regard the actual depth of field of image as a cube, as shown in Figure 3, because translation makes two width of cloth image depth directions at an angle alpha, this angle is called the translational displacement angle.When capture apparatus rotates in the shooting process, as shown in Figure 4, also will produce accordingly an angle beta, this angle is called angle of rotation.In the electronic flutter-proof technology, translational displacement angle and angle of rotation all belong to the change in location parameter, and the translational displacement angle specifically can comprise the translational displacement angle α along X-axis
XWith the translational displacement angle α along Y-axis
Y, because capture apparatus is less on the impact of image definition along the translation of Z axis, so can not consider the translational displacement angle along Z axis, angle of rotation specifically can comprise the angle of rotation β take X-axis as axle
X, the angle of rotation β take Y-axis as axle
YWith the angle of rotation β take Z axis as axle
Z
Electronic flutter-proof is exactly that the first sub-picture of gathering in the shooting duration of once taking is as standard, all the other each sub-pictures and the first sub-picture that adopt the image alignment algorithm to gather in this takes duration are compared, determine translational displacement angle and angle of rotation between relative the first width of cloth image of all the other each sub-pictures, then obtain the mean value at each translational displacement angle and the mean value of each angle of rotation, then based on translational displacement angle mean value and angle of rotation mean value, adopt the image rectification algorithm to calculate translational displacement angle between relative the first width of cloth image of all the other each sub-pictures and the translational displacement angular difference value of translational displacement angle mean value, and with this translational displacement angular difference value as translational displacement angle adjusted value Δ α, also calculate angle of rotation between relative the first width of cloth image of all the other each sub-pictures and the angle of rotation difference of angle of rotation mean value, and with this angle of rotation difference as angle of rotation adjusted value Δ β, then adopt each translational displacement angle adjusted value and each angle of rotation adjusted value, proofread and correct tackling all the other each sub-pictures respectively, then each sub-picture after the first width of cloth image and the correction is superposeed, obtain final photographic images.
Principle based on above-mentioned electronic flutter-proof technology, determined primary importance variable parameter in this step, specifically can comprise: corresponding with second camera, the translational displacement angle adjusted value Δ α along X-axis corresponding to i sub-picture in once taking each sub-picture that gathers in the duration
X, 2, i, along the translational displacement angle adjusted value Δ α of Y-axis
Y, 2, i, the angle of rotation adjusted value Δ β take X-axis as axle
X, 2, i, the angle of rotation adjusted value Δ β take Y-axis as axle
Y, 2, iWith the angle of rotation adjusted value Δ β take Z axis as axle
Z, 2, i, wherein, the value of i is the integer in the 1-N, N is for once taking the quantity of the image that gathers in the duration.
Step S206, based on the primary importance variable parameter of determining, the first camera is carried out electronic flutter-proof and processes taking the image that constantly gathers, specifically can comprise:
At first, because the lens direction of the first camera and second camera differs 180 degree, and two cameras all are relatively static at any time, change without any relative displacement and relative angle between the two, so, when shake occurs in capture apparatus, the absolute displacement of object and sensor devices and rotate equals absolute displacement and the rotation of object and sensor devices in the second camera in the first camera, so the image of synchronous acquisition is compared in two cameras, the image corresponding translational displacement angle and the rotation displacement angle that gather separately exist definite corresponding relation, therefore, can be based on the primary importance variable parameter, determine the first camera and carry out electronic flutter-proof needed second place variable parameter when processing.
Each included concrete parameter of corresponding above-mentioned primary importance variable parameter, second place variable parameter can specifically comprise accordingly: corresponding with the first camera, and the translational displacement angle adjusted value Δ α along X-axis corresponding to i sub-picture in once taking each sub-picture that gathers in the duration
X, 1, i, along the translational displacement angle adjusted value Δ α of Y-axis
Y, 1, i, the angle of rotation adjusted value Δ β take X-axis as axle
X, 1, i, the angle of rotation adjusted value Δ β take Y-axis as axle
Y, 1, iWith the angle of rotation adjusted value Δ β take Z axis as axle
Z, 1, i, wherein, the value of i is the integer in the 1-N, N is for once taking the quantity of the image that gathers in the duration;
Then, according to second place variable parameter the first camera is carried out electronic flutter-proof at the image of taking constantly collection and process, concrete anti-shake processing scheme can adopt prior art, no longer is described in detail at this.
Wherein, when determining second place variable parameter based on the primary importance variable parameter, can whether identical with the focal length of second camera according to the first camera, specifically can comprise following dual mode:
First kind of way: when the focal length of the focal length of the first camera and second camera is identical, the primary importance variable parameter determined is carried out electronic flutter-proof needed second place variable parameter when processing as the first camera.
The second way: when the focal length of the focal length of the first camera and second camera not simultaneously, if needed second place variable parameter when directly the primary importance variable parameter of determining being carried out the electronic flutter-proof processing as the first camera, because the difference of the focal length of two cameras, may be so that last anti-shake treatment effect be not ideal enough, so, propose in the manner, at first based on the primary importance variable parameter of determining, relatively specify the relative ratio of specifying the equivalent focal length of camera with the first camera of equivalent focal length of camera according to second camera, determine that the first camera carries out electronic flutter-proof needed second place variable parameter when processing, for the translational displacement angle adjusted value in the change in location parameter, because the ratio at the translational displacement angle of diaxon equals the ratio that two cameras are specified the equivalent focal length of camera relatively, so specifically can adopt following formula to determine:
Δα
X，1，i?/Δα
X，2，i＝f
1/f
2；
Δα
Y，1，i/Δα
Y，1，i＝f
1/f
2；
Wherein, f
1Be the equivalent focal length that the first camera is specified camera relatively, f
2Relatively specify the equivalent focal length of camera for second camera;
For the angle of rotation adjusted value in the change in location parameter, because angle of rotation value and the rotation direction of three axles are identical, so specifically can be directly with the angle of rotation adjusted value in the primary importance variable parameter as the angle of rotation adjusted value in the second place variable parameter, specific as follows:
Δβ
X，1，i＝Δβ
X，2，i；
Δβ
Y，1，i＝Δβ
Y，2，i；
Δβ
Z，1，i＝Δβ
Z，2，i。
Step S207, taking the image that constantly gathers according to the first camera, needed second place variable parameter when determining to carry out the electronic flutter-proof processing, determining the image of second place variable parameter institute basis in this step, is the image that gathers in the process that the first camera is taken.
Step S208, the image that the first camera is gathered constantly in shooting according to second place variable parameter carry out the electronic flutter-proof processing, and concrete anti-shake processing scheme can adopt prior art, no longer is described in detail at this.
Among the step S207 and step S208 in the above-mentioned method flow shown in Figure 2, to take the image that constantly gathers according to the first camera, needed second place variable parameter when determining to carry out the electronic flutter-proof processing, and only according to second place variable parameter the first camera is carried out electronic flutter-proof at the image of taking constantly collection and process, among other embodiment, can also be after determining second place variable parameter, based on the primary importance variable parameter of determining among second place variable parameter and the above-mentioned steps S205, the first camera is carried out electronic flutter-proof at the image of taking constantly collection process, specific as follows:
Be step S208 specifically can also for: determine the mean place variable parameter of second place variable parameter and primary importance variable parameter, and according to this mean place variable parameter the first camera carried out electronic flutter-proof and processes taking the image that constantly gathers.
The shooting anti-fluttering method that adopts the above embodiment of the present invention 1 to provide, when the definition of the first image that camera gathers of being responsible for taking is hanged down, such as, less than setting clarity threshold, and the definition of lens direction second camera the gather image opposite with the lens direction of the first camera is when higher, such as, greater than setting clarity threshold, be that the definition of image that second camera gathers is during greater than the definition of the first image that camera gathers, carry out electronic flutter-proof needed primary importance variable parameter when processing according to what the image of second camera collection was determined, with determine according to the image of the first camera collection carry out electronic flutter-proof when processing needed second place variable parameter compare, to be more accurate, so, the image of based on the primary importance variable parameter the first camera being taken this moment carries out electronic flutter-proof and processes resulting anti-shake effect, to be better than based on second place variable parameter the first camera being carried out electronic flutter-proof and processing resulting anti-shake effect taking the image that constantly gathers, namely know that through the image of shooting of anti-shake processing degree is higher.
And the definition of working as the first image that camera gathers is not less than the setting clarity threshold, carry out electronic flutter-proof needed second place variable parameter when processing according to what the image of the first camera collection was determined, can satisfy based on second place variable parameter and carry out the electronic flutter-proof processing, and the requirement of the better anti-shake effect of acquisition, so for use and the corresponding use of processing resource of saving second camera, can only according to second place variable parameter, the first camera be carried out electronic flutter-proof at the image of taking constantly collection process.
