Embodiment four
Present embodiments provide a kind of by the implementation of the method for object removal of moving in shooting such as:
Suppose that mobile terminal pipe is provided with n camera, form camera set C={c
1, c
2... c
n, wherein, c
irepresent i-th camera.
For each camera, in its camera lens sometime, there is m target, form goal set P={p
1, p
2..., p
m, wherein, p
irepresent i-th target.
For each target, all use series of features parameter sets U={U
1, U
2..., U
tcharacterize this target.Namely for pi, a U is had
pi={ U
pi1, U
pi2..., U
pic.This characteristic parameter can increase and decrease according to actual conditions.Mainly use four parameters herein: U={V, S, L, F}.Wherein, V representation speed, S represents size, and L represents position, and F represents shape.
In each camera, the parameter circular of each target is as follows:
First, the coordinate system x-o-y of a camera is set up;
V: the speed of target movement, can by solving the distance s of target travel within a certain period of time and being calculated by the time t that this segment distance is used, i.e. V=s/t;
S: the size of target, due to the diversity of target shape, according to the knowledge of image procossing, can use the area W of the external profile of target to carry out the size of approximate target; Therefore the size of i-th target is W
i.
L: the position of target, represents by the center position of its profile.The position of i-th target is (x
i, y
i), wherein, x
i, y
icentered by put horizontal ordinate and the ordinate of position.
F: owing to being the target of camera, for its each target, it has the change of yardstick, characterize its size, needs to represent with the amount that dimensional variation is irrelevant with one.This method uses the depth-width ratio of the external profile of target to characterize the form parameter of target.Be specially H
i/ B
i, wherein, H
irepresent the height of i-th external profile of target, B
irepresent the width of i-th external profile of target.
The detailed process of this patent is as follows:
First, set one section of photo opporunity T, within this time, each camera is taken N continuously and is opened photo;
Then, for N pictures, carry out motion estimate:
For each camera, the N pictures of its shooting, carries out moving object detection by the method based on image difference, thus identifies moving target.
For the target identified, by picture and the parameter such as time interval of shooting, calculate the set of characteristic parameters U of target at each shooting time point.
Thus for the sequence of pictures that each camera photographs, it can both obtain a set of characteristic parameters.
Afterwards, moving target Parameter fusion is carried out to the photo that each phase of multi-cam is taken in the same time.
I.e. synchronization, gets the mean value of the target component of multiple camera;
As the position L=(x of target
i, y
i),
Target location then after multi-cam Parameter fusion is
Other parameters are get this parameter of multi-cam moving target to average equally.
Now, the set of characteristic parameters of multi-cam moving target is obtained;
Afterwards, on the basis of the set of characteristic parameters merged, carry out moving target and remove operation:
Remove operation specific as follows:
In the sequence of set of characteristic parameters, navigate to the moment that velocity to moving target is maximum, take out the picture captured by each camera corresponding to this moment, construct the profile of its target, time speed is maximum, the motion amplitude of its target is maximum.The position of known camera, by the method that visual angle is synthesized, the picture that this moment of different camera photographs is synthesized, and carry out objective contour identification on the picture of this synthesis, get rid of the pixel (replacing with 0) in this contour area, thus obtain exercisable image A.
For other moment, carry out visual angle synthesis and target localization equally, for the image after synthesis, target location is searched for and mates, if the element that the profile of this target and position do not overlap completely with the objective contour in image A and position, then claim image now for can application drawing as B, in image B, utilize the pixel position L of coordinate in image A corresponding to moving target and profile, retain the pixel that L is corresponding in image B, other pixels in image B are all set to 0, thus obtain exercisable image C, then A and C is synthesized, obtain image D, thus achieve removing of moving target.
The present embodiment is first synthesized by the photo that all cameras are taken at synchronization, two photos that the objective contour filtered out again in the photo of synthesis does not overlap completely, carry out deleting, synthesizing thus the object removal that will move, make the recognition accuracy of objective contour after synthesizing high, thus by better effects if that this moving target removes.
The present invention by different camera is screened automatically in the scene that the different moment takes simultaneously, synthesize, the deletion of target finally synthesizes again, the identification making moving target and the better effects if removed, also better solve the target occlusion problem of single camera.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
