Abstract
The present invention provides a kind of virtual camera and is aligned with real camera,Include real camera including the virtual camera and real camera contraposition and virtual camera aligns,Assuming that CMOS positions B points are represented on video camera,R1 corrects point for system support,Made by infrared light reflecting material,Can be A' points by motion capture system identification,Virtual camera focal length is consistent with real camera,In virtual scene,Make the dummy object A' that radius is equal to R1,Under 4K resolution ratio,Use the position of specific software adjustment A ',A' and R1 is adjusted to overlap,Under 4K resolution ratio,Use the position of specific software adjustment A ',A' and R1 is adjusted to overlap,The present invention is using virtual shooting principle,Can be completely superposed the position of virtual camera and the CMOS positions of real camera,Simple operation,It is easy to implement.
Description
Technical field
The invention belongs to virtual camera technology field, more particularly to a kind of virtual camera to align with real camera.
Background technology
Virtual camera equipment is to be combined using Computer Aided Graphic Design technology with virtual reality technology, and products application is in video display
Special efficacy, three dimensional design and virtual reality applications, the product design concept are to solve three-dimensional video camera and real camera
Position correspondence problem.
Virtual camera technology is the core technology in virtual reality, passes through virtual camera and really pair of video camera
Position, can be by three-dimensional virtual scene and really photographed scene is synthesized.It is video display special efficacy, virtual reality, three dimensional design etc. should
Core technology.
Therefore, a kind of virtual camera is invented to be very necessary with real camera contraposition.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of virtual camera and is aligned with real camera.
A kind of virtual camera is aligned with real camera, it is characterised in that the virtual camera and real camera pair
Position includes real camera and virtual camera aligns, it is assumed that CMOS positions B points is represented on video camera, R1 rectifys for system support
On schedule, made by infrared light reflecting material, can be A' points by motion capture system identification, virtual camera focal length and truly taken the photograph
Camera is consistent, in virtual scene, makes the dummy object A' that radius is equal to R1, under 4K resolution ratio, uses specific software tune
The position of whole A ', adjusts A' and R1 and overlaps, and under 4K resolution ratio, using the position of specific software adjustment A ', adjusts A' and R1 weights
Close.
Compared with prior art, the present invention has the advantages that：The present invention can be made virtual using virtual shooting principle
The position of video camera and the CMOS positions of real camera are completely superposed, and simple operation is easy to implement.
Brief description of the drawings
Fig. 1 is structure principle chart of the present invention.
Embodiment
The present invention is described further below in conjunction with attached drawing：
Embodiment：
As shown in Figure 1, the present invention provides a kind of virtual camera and is aligned with real camera, it is characterised in that this is virtually taken the photograph
Camera includes real camera with real camera contraposition and virtual camera aligns, it is assumed that CMOS positions are represented on video camera
B points, R1 correct point for system support, are made by infrared light reflecting material, can be A' points by motion capture system identification, virtually
Focal length of camera is consistent with real camera, in virtual scene, make radius be equal to R1 dummy object A', 4K resolution ratio it
Under, using the position of specific software adjustment A ', adjust A' and R1 and overlap, under 4K resolution ratio, use specific software adjustment A's '
Position, adjusts A' and R1 and overlaps.
Operation principle
The present invention is combined using Computer Aided Graphic Design technology with virtual reality technology, and products application is in video display special efficacy, three dimensional design
And virtual reality applications, solve the problems, such as the position correspondence of three-dimensional video camera and real camera, it is convenient to carry out
Designed using technical solutions according to the invention, or those skilled in the art under the inspiration of technical solution of the present invention
Go out similar technical solution, and reach above-mentioned technique effect, be to fall into protection scope of the present invention.
