Description
Technical field
The present invention relates to virtual studios, more specifically refer to implementation method, the device, computer of unlimited blue-box function
Equipment and storage medium.
Background technique
A kind of important means made as the Virtual Studio System of technology as real time TV, mesh are scratched based on blue case
Before be widely used in all kinds of television program designings, Virtual Studio System obtains foreground image by video camera, and by with
The kinematic parameter of track system acquisition video camera；Graphics workstation generates three-dimensional virtual scene according to the kinematic parameter of video camera in real time
Background signal and mask signal；Camera video signal, three-dimensional virtual scene signal and mask signal are being scratched as synthesizer
In carry out scratch as synthesize and be output to video recording equipment.Virtual Studio System can with the position of autotracking video camera, yawing, bow
It faces upward and the Parameters variations such as the focusing of camera lens and zoom, changes three-dimensional virtual scene in real time according to these parameters, make three-dimensional
The variation of scene is synchronous with the movement of video camera holding and consistent, ensure that the correct perspective relation of foreground and background, in prospect
Host seem to be immersed in three-dimensional virtual scene caused by computer completely, imitated with television stadio true to nature
Fruit.
Due to the limitation in place in practical studio, when video camera carries out when push-and-pull such as moves at the movement outside indigo plant case region
Scenery can enter foreground video signal, this foreground video signal is being scratched as carrying out scratching picture with three-dimensional virtual scene in synthesizer
When synthesis, the scenery outside these blue case regions be may also appear in the video of output, foreground image required for being not achieved and void
The effect of quasi- scene fusion.Therefore unlimited blue-box function must be realized in Virtual Studio System, unlimited blue-box function effect is
When video camera shakes out blue case, the video signal area of scenery is filled with background outside blue case region, prevents phenomenon of exposing the false, really
Realize being perfectly combined for virtual background and foreground signal.Scratch the function of having control key window as synthesizer, Ke Yi
Region unwanted in foreground video signal is excluded except key window when scratching as synthesis, so that the region is three in synthesis
Virtual scene is tieed up, subregional effect in the middle part of prospect of blocking is reached.Controlling key window, generally there are two types of implementations: first is that passing through
The size of window is directly arranged in numerical value, second is that determining window according to video pixel value in mask signal by input mask signal
Region.
Both implementations of corresponding control key window, there are two types of the generation methods of unlimited blue-box function at present:
One is a three-dimensional inclusion body is built in three-dimensional virtual scene by 3 d rendering engine control interface
To restore true studio, and the size of inclusion body, position of the 3 d rendering engine according to real camera, angle are adjusted in real time
And three-dimensional inclusion body is mapped as X-Y scheme in real time and is exported by α key by zoom parameters, final system is exported by α key
The minimum of planar graph include quadrangle edge, adjust the dynamic infinite blue box edge of chroma key device in real time by serial ports to complete
Dynamic infinite blue box parameter setting.Another is the supplementary set Area generation dough sheet structure in blue case, constitutes a solid, several
Each face of what body is plane, each plane is used as exposure mask, and the signal of filling is background signal；When video camera shakes out
When blue case region, rendered in Alpha caching using these as the plane of exposure mask, while according to prospect, background and blocking pass
System, the three-dimension object for being used for the prospect of blocking is extracted and is rendered in Alpha caching, and the image of rendering is synthesized video all the way
Signal is output to chroma key by the channel Alpha, is synthetically generated in real time as external key and background, prospect and embodies 3-D effect all the way
Video image.
But the generation method of the first above-mentioned unlimited blue-box function does not match true blue case size, it can only basis
The viewfinder range of video camera generates three-dimensional inclusion body under initial attitude, so that the blue case outside viewfinder range is also treated as blue case
Outside region.The generation method of second of unlimited blue-box function according to blue case full-size(d) blue case supplementary set Area generation dough sheet knot
Structure constitutes a solid, each face of solid is plane, each plane is used as exposure mask, and the signal of filling is
Background signal；So that the method is only suitable for rectangular blue case: u-shaped, left L-type indigo plant case, right L-type indigo plant case.For sector, and it is irregular
The blue case of shape cannot then match, in addition the such as 180 degree when video camera wide-angle yawing, when exceeding dough sheet region, still can
Cause phenomenon of exposing the false.
Therefore, it is necessary to design a kind of new method, realization establishes infinite blue box region to the blue case of arbitrary shape, improves
The utilization rate in blue case region.
