Intensity profile figure is first calculated as follows：Hk(i)=∑jIk(i, j), wherein, k is 1 or 2, refers to piece image or the second width respectively
Image；Then vertical parallax d is calculatedv=argmind∑i|H1(i)-H2(i+d)|；Eliminate vertical parallax after piece image and
Second width image is preferably I '1(i, j)=I1(i-dv/ 2, j), I '2(i, j)=I2(i+dv/ 2, j)；First width figure after handling
Picture and the second width image synthesize 3D images by default 3D forms.
The beneficial effects of the present invention are：The 3D image shooting methods of single camera proposed by the present invention, it is possible to achieve single
The 3D filming images of camera, reduce the luminance difference of piece image and the second width image, eliminate vertical parallax, improve 3D and regard
Feel effect.
Brief description of the drawings
Fig. 1 is the flow chart of the 3D image shooting methods of single camera of the present invention.
Embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Embodiment one
Referring to Fig. 1, present invention is disclosed a kind of 3D image shooting methods of single camera, 3D is shot using single camera
Image；The image pickup method comprises the following steps：
The first step, selects scape to shoot piece image as left figure or right figure, its key is just to determine 3D shadows using camera
The coverage of picture.
Second step, using camera preview image and the first width image construction stereo pairs, and shows according to bore hole 3D
The characteristics of carry out synthesis in real time and display, user determines 3D images according to the 3D effect of display.
3rd step, according to 3D filming images the second width image of determination, before three steps area-of-interest it is identical, often walk
Focusing area should be area-of-interest, to avoid image out of focus.
4th step, is handled piece image and the second width image, reduces difference between image, eliminates vertical parallax；
Because image is shot in different time points, even if interval time is short, it is also possible to because environmental change causes the difference of brightness etc., with the
Piece image is that target does histogram specification to the second width image, can reduce difference between image, improve 3D visual effects；3D shows
Showing have vertical parallax, otherwise can cause piece image and the second width image in serious visual problem, shooting process
There may be vertical parallax, intensity profile statistics can be carried out in vertical direction, and vertical parallax is calculated using intensity profile, then
Eliminate vertical parallax；Intensity profile figure is first calculated as follows：Hk(i)=∑jIk(i, j), wherein, k is 1 or 2, refers to first respectively
Width image or the second width image；Then vertical parallax d is calculatedv=argmind∑i|H1(i)-H2(i+d)|；Eliminate after vertical parallax
Piece image and the second width image be preferably I '1(i, j)=I1(i-dv/ 2, j), I '2(i, j)=I2(i-dv/ 2, j)；Will
Piece image and the second width image synthesize 3D images, such as left and right 3D rendering by default 3D forms after processing.
5th step, by synthetic 3D Image preservations on a storage medium.
In summary, the 3D image shooting methods of single camera proposed by the present invention, it is possible to achieve the 3D shadows of single camera
As shooting, the luminance difference of piece image and the second width image is reduced, vertical parallax is eliminated, 3D visual effects are improved.
