Embodiment
Refer to Fig. 1, the method for a kind of image simulation revisal provided by the invention, includes following steps:
(a) first, set up a flat image in a memory body, it can utilize a camera to take in advance this flat image, and this flat image is stored in this memory body.
(b) utilize this camera to take an instant video with this flat image, and compare out the different parts in this instant video according to this flat image, then take out after this different piece is judged as to a main body image.Its comparison mode, according to the GTG difference in this flat image and instant video picture element, when the GTG difference of picture element is greater than a predetermined value, judges that this picture element is the picture element of main body image, and thus to obtain this main body image.
(c) according to the light source reflective information of this main body image, those parts of judging in this main body image should belong to concave surface, those parts should belong to convex surface, meaning, by the difference of light source reflective information, to judge the stereoscopic-state of this main body image in true environment, and select by this axially datum mark of position of a plurality of x of having, y;
Then calculate the axial position of desirable z of this each datum mark, and the actual projected length of this each datum mark, according to the actual projected length of this each datum mark, draw the compensating value of relative datum point, with this compensating value, the desirable z of this each datum mark is axially carried out to revisal in position again, make the z of this each datum mark after revisal axially extend to correspondence position in position, to simulate the main body image that generates curved surface.
Calculate the axial position of desirable z of this each datum mark and the step of actual projected length, illustrate as follows:
For example the rectangular equation formula of a ball is x
2+ y
2=z
2.
And the radius that r is ball, so x=γ cos θ; Y=rsin θ; Z=C1(constant)
Carry it into x
2+ y
2=z
2formula in, can draw:
Again, cos
2θ+sin
2θ=1
So r
2(1)=z
2→ γ
2=z
2→ γ=z, and can utilize thus x, the y that each datum mark is known axially to calculate the axial bit length of its desirable z in position, and the length of the axial position of z equal the radius r of ball.
And when z is when axially the length of position is known, axially in length generation of position, goes out to include a compensating value to parallactic angle compensating value and an anglec of rotation compensating value can further to utilize z.
As shown in Figure 2, known according to trigonometric function formula
and aforementioned calculating formula has obtained r=z, therefore
when
time, r=ρ, now ρ is actual projected length.
And further consider the change of pitch angle difference of this main body image, therefore again a variable value ι is added, make the rectangular coordinates equation of ball be:
x
2+ιy
2=C1
From aforementioned calculating formula, x=rcos θ, y=rsin θ, and will
substitution x
2+ ι y
2in the rectangular equation formula of=C1, obtain:
Wherein ι is complex variable value,
for to parallactic angle compensating value, θ is anglec of rotation compensating value,
for actual projected length.And thus carrying out image simulation emulation corresponding to emulation according to the degree of freedom of main body movement track.
Then with the approaching rule of Riemann's element, getting the limit again obtains the more real compensating value of convergence:
C2 wherein, C3, C4, C5 is respectively a constant.And can draw according to the actual projected length of this each datum mark the compensating value of relative datum point thus, then with drawn compensating value, the desirable z of this each datum mark is axially carried out to revisal in position.In detail, main body image of the present invention is to extend to correspondence position according to the axial position of the z of this each datum mark after revisal, with simulation, generate the main body image of curved surface, then can carry out for the main body image through curved surface the revisal action of light source and aberration, and the point-to-point emulation of mat and aspectant revisal, significantly promote the soften of the curved surface after this main body image curved surface, and then make the main body image after curved surface more natural.
(d) last, then by the main body image through curved surface with this flat image after a processing unit is synthesized (Interweaving), can obtain the simulating image that plane 2D+ simulates curved surface 3D.
Actual operation situation of the present invention is as shown in annex one, in annex one photo, shown hand is because of in mobile status, therefore can be according to its light source reflective information, to judge concave/convex, and select by this axially datum mark of position of a plurality of x of having, y, to carry out the computing of follow-up simulation curved surface, and the revisal of light source and aberration action; And annex two is in order to show that the present invention is after simulating the computing of curved surface, it is for light source and the forward and backward image comparison photo of achromatic, and in this actual test, adopt the mode of strengthening image contrast to carry out the revisal action of light source and aberration, and can know and find out by annex two its photos after revisal, redness in its image of image after revisal is more bright-coloured, and the details lines of its hand more obviously, truly, and can reach by this image effect of high image quality.
And image simulation correction method provided by the present invention, only need be with a camera, the flat image simulation of 2D can be generated to the 3D image of emulation, not only can effectively reduce equipment cost and reduce outside user's human load, utilization of the present invention calculates the compensating value of this each datum mark, and can be for the light source of the main body image of its curved surface, aberration and curved surface carry out emulation revisal, and by point-to-point emulation and aspectant revisal, more can significantly promote curved surface soften and the validity of this main body image after curved surface, and and then make the present invention only must adopt the camera lens module that general cost is cheaper, can reach the image effect of high image quality.Moreover, because the present invention only carries out the emulation revisal operation of curved surface for the main body image that is different from flat image in instant video, therefore except can effectively reducing its processing time, more can reach the effect of the archives capacity that significantly dwindles its resultant image.
