Second embodiment
With reference to Fig. 2, it is shown that the flow chart of the method that a kind of multi-medium data of another embodiment of the present invention shows, this Inventive embodiments can apply to monitoring system, smart mobile phone, flat board, palm PC (Personal Digital Assistant, PDA), photographing unit etc. have in the electronic equipment of photographic head, further, this electronic equipment can also include showing Display screen, wherein, the photographic head in electronic equipment is taken pictures for realization, camera function, and display screen is for realizing shooting picture Or the preview function of video, i.e. shown in real time by the picture of absorption current to photographic head, for user's preview, thus Reach the effect of view finder.
In embodiments of the present invention, photographic head can include main photographic head and multiple auxiliary photographic head, wherein, main photographic head May be used for shooting and specify the overall image of photographed scene, therefore, main photographic head is referred to as overall situation photographic head.Auxiliary shooting Head may be used for shooting and specifies the image of local scene in photographed scene, and therefore, auxiliary photographic head is referred to as local cameras.
The optical zoom multiple of this auxiliary photographic head is more than the optical zoom multiple of this main photographic head, in the one side of being preferable to carry out In formula, this main photographic head can be a Zoom Lens photographic head, and the plurality of auxiliary photographic head can be more than a Zoom Lens Photographic head, such as, the plurality of auxiliary photographic head can be standard varifocal photographic head module or for the varifocal photographic head of focal length (standard varifocal photographic head module and the difference on optical zoom of the focal length varifocal photographic head module, be mainly reflected in module The multiple that the former can amplify is big less than the latter, and such as the former maximum may accomplish 3 Zoom Lens, and the latter then may maximum do To 12 Zoom Lens).
In a preferred embodiment, the plurality of auxiliary photographic head can be arranged in rectangular array, and this main photographic head exists Outside this rectangular array and adjacent with this rectangular array.With reference to shown in the camera array cross sectional representation shown in Fig. 3, many Individual auxiliary photographic head 302 can be arranged in the rectangular array of 4*3, and (this is corresponding with the sensor devices of photographic head, the sense of photographic head Optical device is also rectangle, and length-width ratio is 4:3), main photographic head 301 is outside this rectangular array and adjacent with this rectangular array.
It should be noted that when receiving shooting instruction or the record command of user, main photographic head and multiple auxiliary take the photograph As head can be simultaneously to specifying photographed scene to shoot or record, the shooting of the most main photographic head is overall photographed scene, The shooting of auxiliary photographic head is photographed scene locally.
The embodiment of the present invention may include steps of:
Step 201, is 1 Zoom Lens by the Focussing of main photographic head, and respectively by the focal length of multiple auxiliary photographic head Adjust to default optical zoom multiple.
Specifically, before sending shooting instruction or record command, first user can set main photographic head and take the photograph with auxiliary Optical zoom multiple as head.In a preferred embodiment, the focal length of main photographic head can be set to 1 times of optics by user Zoom, and respectively the focal length of multiple auxiliary photographic head is set to the optical zoom multiple preset.
And the optical zoom multiple preset of auxiliary photographic head be exactly when broadcasting video or image, user is to video or image A certain local carries out optical zoom and amplifies the multiple checked.
It should be noted that user can the optical zoom multiple of this auxiliary photographic head of on-demand setting, but due to optical zoom Multiple is proportionate with photographic head number, and therefore, this optical zoom multiple should not arrange excessive, and multiple is the biggest, needs the most Auxiliary photographic head processes.Such as, auxiliary photographic head shoots appointment photographed scene according to two times of focal lengths, and in object distance, (object is to camera lens Distance) identical in the case of, two times of focal length photographic head visual angles are little relative to one times of focal length photographic head, and the picture of absorption is the least. The photographic head of each two times of focal lengths is only responsible for the absorption of a certain local in present filming scene, is such as the 1/ of this photographed scene 100, then there are 100 two times of focal length photographic head to take in simultaneously, thus can guarantee that whole photographed scene is taken in enter, i.e. two During times focal length, 100 auxiliary photographic head can completely be taken in whole photographed scene, now, if being three by two times of Focussings Times focal length, in the case of the quantity of auxiliary photographic head is fixing, the camera lens of each auxiliary photographic head can only take in whole photographed scene 1/150, the camera lens of these 100 auxiliary photographic head can only take in the 100/150 of whole photographed scene altogether, also differs from 50 auxiliary photographic head Camera lens.Therefore, when the auxiliary photographic head number of equipment is fixed, its optical zoom multiple just has maximum, and the optics that user sets becomes Burnt multiple should be less than the maximum of this optical zoom multiple.
In practice, when the optical zoom multiple of the auxiliary photographic head of user setup, electronic equipment can be by this optical zoom The maximum of multiple is prompted to user, and the optical zoom multiple pointing out user to set not can exceed that this optical zoom multiple is Big value.Such as, according to the quantity of the auxiliary photographic head of current electronic device, limit the maximum of optical zoom multiple as 4 times, then may be used Not can exceed that 4 times of focal lengths with the optical zoom multiple that prompting user sets.
In addition, it is necessary to explanation, after the optical zoom multiple setting auxiliary photographic head, this optical zoom multiple The optical zoom multiple of all auxiliary photographic head being applicable to all auxiliary photographic head, i.e. current electronic device is all consistent.Or, In another scene, user can also set optical zoom multiple, the embodiment of the present invention pair respectively for each auxiliary photographic head This is not restricted.
After user sets the optical zoom multiple of each photographic head, when starting recorded video or shooting image, Main photographic head can be kept 1 Zoom Lens by electronic equipment, and direction faces toward the appointment photographed scene of dead ahead, and, by institute There is a Focussing optical zoom multiple to this setting of auxiliary photographic head, and the direction of all auxiliary photographic head is adjusted to faces Specify the direction of photographed scene.
Step 202, carries out angular deflection calibration to auxiliary photographic head each in the plurality of auxiliary photographic head.
After completing the optical zoom adjustment of all photographic head in step 201, can be further to all auxiliary photographic head In each auxiliary photographic head carry out angular deflection calibration.
In one embodiment, in the following way each auxiliary photographic head can be carried out angular deflection calibration: obtain The preview screen region that main photographic head gathers for appointment photographed scene, and, the quantity of auxiliary photographic head；By this preview screen district Territory is divided into the preview screen region, local of the appointment size of the quantity respective amount with auxiliary photographic head；It is respectively multiple auxiliary shootings In Tou, each auxiliary photographic head distributes the preview screen region, local of a correspondence position；For each auxiliary photographic head, based on distribution The locally center in preview screen region, carries out angular deflection calibration.
Specifically, owing to main photographic head is for shooting the overall scenario specifying photographed scene, therefore, main photographic head can Gather the preview screen region of whole appointment photographed scene.Further, owing to the quantity of photographic head auxiliary in electronic equipment is fixing, Therefore, it can the definite quantity obtaining auxiliary photographic head.
Subsequently, the preview screen region specifying photographed scene of main camera collection can be divided into and auxiliary photographic head The preview screen region, local of the appointment size of quantity respective amount, and in the most multiple auxiliary photographic head, each auxiliary photographic head divides Join the preview screen region, local (i.e. local scene) of a correspondence position.Such as, such as the photographic head relations of distribution schematic diagram institute of Fig. 4 Showing, current device has 12 auxiliary photographic head, then be divided in the preview screen region specifying photographed scene of main camera collection Preview screen region, 12 local, the lower right corner is the camera array of the embodiment of the present invention, and it is that 4x3 auxiliary photographic head adds one again Individual main photographic head.The upper left corner is an appointment photographed scene that will take in, and length-width ratio is 4:3, according to the quantity of auxiliary photographic head (12), can be divided into the preview screen region, 4x3 local of formed objects, and be that each auxiliary photographic head distributes a pair Answering the preview screen region, local of position, every solid line drawn from auxiliary photographic head points to specifies the local photographed scene pre- Picture area of looking at is exactly the one-to-one correspondence showing auxiliary photographic head with preview screen region, local.
In practice, owing to when initializing, whole photographic head are all just front to be specified photographed scene, now, If taking an intermediate image with the preview screen region, local that all of auxiliary photographic head is just corresponding respectively, and auxiliary take the photograph all As the intermediate image of head shooting pieces together, it is not necessary to complete one secondary scene can be pieced together, because auxiliary photographic head is all greater than one Zoom Lens, the angle of visual field is little relative to one times of zoom lens, and the scene of absorption is the least.If calibrated without angular deflection, The image of rear synthesis is exactly the image of overlapping region.Based on this, in embodiments of the present invention, right for the distribution of each auxiliary photographic head After the preview screen region, local answered, correspondence can be carried out based on the center in the preview screen region, local distributed The angular deflection calibration of auxiliary photographic head.
In one embodiment, can the centre bit in preview screen region, local based on distribution in the following way Putting, the angular deflection of the auxiliary photographic head carrying out correspondence is calibrated: the center in preview screen region, described local based on distribution, Judge that described auxiliary photographic head is the need of carrying out angular deflection calibration；If described auxiliary photographic head needs to carry out angular deflection calibration, Then obtain the diagonal intersection point of described rectangular array, be set as O point；Obtain the camera lens center of circle of auxiliary photographic head the most to be calibrated, It is set as P point；The yawing moment of described auxiliary photographic head is defined as the direction of the directed line segment of OP；Side by described directed line segment Need the angle carrying out calibrating as described auxiliary photographic head to the angle offset relative to Z axis.
In implementing, if with all auxiliary photographic head respectively with regard to the center bat in corresponding preview screen region, local Next intermediate image, and all intermediate images are synthesized first image, just specify scene to take with main photographic head simultaneously One the second image；First image and the second image are contrasted, if these two picture registrations are completely the same, then it represents that auxiliary take the photograph As head is made without angular deflection calibration.Otherwise, if these two images can not be completely superposed, then it represents that auxiliary photographic head need into Row angular deflection is calibrated.
In one embodiment, as shown in the calibration schematic diagram of Fig. 5, if auxiliary photographic head needs to carry out angular deflection school First standard, then can determine the diagonal intersection point of the rectangular array that these all auxiliary photographic head form, it is assumed that this point is O point, then The camera lens center of circle of auxiliary photographic head the most to be calibrated is set as P point, and the direction of the directed line segment of OP is corresponding as this O point The yawing moment of auxiliary photographic head, then the direction of the directed line segment that angle is this OP that this auxiliary photographic head needs to carry out to calibrate is relative In the angle of Z axis skew, subsequently, deflection calibration can be carried out according to this angle.The angular deflection of other auxiliary photographic head is calibrated also It it is similar operations.
It should be noted that for the accuracy improving calibration, above-mentioned angular deflection calibration may need to carry out repeatedly, directly The second image that the first image pieced together to the intermediate image of multiple auxiliary photographic head shooting and main photographic head shoot is completely superposed Unanimously, this angle calibration system just completes.
Step 203, controls described main photographic head and shoots described appointment photographed scene, it is thus achieved that the first multi-medium data；And, Control the plurality of auxiliary photographic head and shoot the corresponding local scene of described appointment photographed scene respectively, it is thus achieved that the many matchmakers in multiple centres Volume data.
After the angular deflection completing auxiliary photographic head is calibrated, it is auxiliary with all that electronic equipment can control main photographic head simultaneously Appointment photographed scene is shot by photographic head.

Concrete, in order to eliminate the impact of multimode background and moving target, can obtain first with gauss hybrid models To the background image of each middle multi-medium data, as a kind of example, number K of Gauss model can be set to 5, and threshold value T sets Being 0.7, length of window L is set to 200, and primary standard difference σ is set to 20.
Subsequently, respectively each background image can be carried out SIFT (Scale-invariant feature Transform, scale invariant feature is changed) detection of characteristic point and coupling, and utilize RANSAC (RANdom Sample Consensus, it is according to one group of sample data set comprising abnormal data, calculates the mathematical model parameter of data, obtains The algorithm of effective sample data) algorithm elimination exterior point therein.Impact in view of the measurement error of alignment procedures, it is also possible to profit Calculating homography matrix with the symmetrical transmission error of feature point pairs, this object function can be expressed as:
∑[d(xi, H-1x′i)2+d(x′i, Hxi)2]；
In above formula, the 1st transmission error representing present frame, the 2nd transmission error representing former frame；Table Showing the ith feature point pair of former frame and present frame, H represents the projective transformation of two width images.
Auxiliary photographic head a fairly large number of in the case of, global optimization approach can be used to eliminate the accumulation of error, and obtain The global alignment parameter of each auxiliary photographic head.Owing to global approach amount of calculation is bigger, frame-to-therefore can be used Mosaic (frame is to panorama sketch) method calculates the global alignment parameter of each auxiliary photographic head.For example, it is assumed that there are 4 auxiliary photographic head Background image Ci(i=1 ..., 4).First one of them background image is chosen (such as Ci) as reference frame, and C2It is registered to C1, Thus generate an interim stitching image M.Then background image C3It is directed at M, and utilizes C3M is updated.Right C4Same method is used to process, such that it is able to obtain the alignment parameter of all background images.
Homography matrix between each auxiliary photographic head, once it is determined that the most no longer change, utilizes these global alignment parameters Each middle multi-medium data is projected in global coordinate system, it is possible to they are synthesized the second multi-medium data.
It should be noted that the above-mentioned mode that middle multi-medium data is carried out synthesis process is only the embodiment of the present invention A kind of example, this area adopts and middle multi-medium data carries out synthesis in other ways processes and be all possible, and the present invention is real Execute example this is not restricted.
It should be noted that the resolution of this second multi-medium data is different along with the difference of optical zoom multiple, light Learn zoom magnification the biggest, then the resolution of the second multi-medium data is the biggest.And dividing of its resolution ratio the first multi-medium data Resolution is big.
