Abstract
The invention discloses a method for realizing spherical transition special effects. The method comprises the following steps: establishing a spherical model on an xyz axis space; obtaining video data; calculating a center of the spherical model and a focus point of the video data; wrapping the spherical model by the video data by using the focus point as the center; and displaying a corresponding image by the video data through the position of the spherical model. By adopting the method disclosed by the invention, the making efficiency of a program is greatly increased, the function of hardware is expanded, and higher freedom is obtained.
Description
Technical field
The present invention relates to field of broadcast televisions, relate in particular to a kind of method that realizes spherical transition special effective.
Background technology
Films such as the film that present spectators are watched, TV play all can add special efficacy through post-production.And transition special effective also is the most common a kind of special efficacy.Now spectators watch film to be not limited to the plot of film, more are the vision shocks that special efficacy that film adds is brought.Therefore, more special efficacy is by developing gradually.
The least unit that constitutes telefilm is a camera lens, and the shot sequence that is joined together to form of camera lens is called paragraph one by one.Each paragraph all has certain single, complete relatively meaning, as shows a course of action, shows a kind of dependency relation, shows a kind of implication or the like.It is complete narration level in the telefilm, and just as the curtain in the drama, fictitious chapters and sections are the same, and paragraph links together one by one, has just formed complete telefilm.Therefore, paragraph is the most basic version of telefilm, and telefilm layer of structure in terms of content shows through paragraph.And transition between paragraph and paragraph, scene and the scene or conversion are referred to as transition.
The method of transition is a lot, on connected mode, also can be divided into skill transition and two big types of no skill transitions.Skill transition: utilize the stunt skill that two paragraphs are connected together.Be characterized in: both caused linking up of vision easily, caused the separation of paragraph again easily.The skill conversion is usually used in the conversion of big paragraph, than being easier to form tangible paragraph level.Usual way: fade over, dissolve, page turning, draw picture, iris out and ensphere, fix etc.No skill transition: adopt direct switching way, connect two sections contents with the natural transition of camera lens.
The inventor finds that in carrying out R&D process there is following defective in prior art when making transition special effective:
(1) transition special effective effect of the prior art is single, can not well improve the video displaying quality;
(2) making of special efficacy need be bought specific hardware and could realize that still cost an arm and a leg, limitation is low.
Summary of the invention
The embodiment of the invention provides a kind of method that realizes spherical transition special effective, greatly improves the make efficiency of program, has expanded the function of hardware, has the high degree of freedom.
This method specifically may further comprise the steps:
A kind of method that realizes spherical transition special effective, this method comprises:
On the xyz shaft space, set up spherical model;
Obtain video data;
Calculate the center of said spherical model and the focus of said video data;
Said video data is that said spherical model is wrapped up at the center with said focus;
Said video data shows corresponding image through the position of said spherical model.
Said spherical model can be around X axle, Y axle and/or the rotation of Z axle, along translation on X axle, Y axle and/or the Z axle, along convergent-divergent on X axle and/or the Y axle.
Said video data is to comprise after said spherical model is wrapped up at the center with said focus: call tinter said spherical model is played up.
The said spherical model of on the xyz shaft space, setting up comprises before: make up xyz shaft space coordinate system.
Said xyz shaft space coordinate system comprises: visual angle coordinate system and/or projected coordinate system.
The position of said video data through said spherical model shows that corresponding image specifically comprises: when move, after rotation and/or the said spherical model of convergent-divergent; Again obtain the center of said spherical model and the focus of said video data, said video data is that said spherical model is wrapped up at the center with said focus.
According to the embodiment of the present invention, through making up spherical model, and show corresponding video image in real time, greatly improve the make efficiency of program, expanded the function of hardware, have the high degree of freedom according to the position of spherical model.
Description of drawings
Technical scheme for the clearer explanation embodiment of the invention; The accompanying drawing of required use is done simple the introduction in will describing embodiment below; Conspicuous, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
A kind of flow chart of realizing the method for spherical transition special effective that Fig. 1 is provided for the embodiment of the invention one.
Embodiment
To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, complete description; Obvious described embodiment only is a part of embodiment of the present invention, is not whole embodiment, based on the embodiment among the present invention; Those of ordinary skills are not paying the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Embodiment one
A kind of flow chart of realizing the method for spherical transition special effective that Fig. 1 is provided for the embodiment of the invention one.
Of Fig. 1, this method may further comprise the steps:
Said visual angle coordinate system: with point of observation (human eye, video camera) is the origin of coordinates, observes the scene in the world coordinate system, identical scene, and the scene that different points of observation appears on the perspective plane is different.
Said projected coordinate system: the scene in the coordinate system of visual angle is three-dimensional; Mock inspection point or video camera are observed scene, can only see the scenery of certain angular field of view, and the distance of observing simultaneously also has certain limitation; So projected coordinate system is a cone.Scene between its head-on view and the backsight face is the scene that really can show.
According to the embodiment of the present invention, through making up spherical model, and show corresponding video image in real time, greatly improve the make efficiency of program, expanded the function of hardware, have the high degree of freedom according to the position of spherical model.
Through the description of above execution mode, those skilled in the art can be well understood to the present invention and can realize through software, also can realize by the mode that software adds necessary general hardware platform.Based on such understanding; Technical scheme of the present invention can be come out with the embodied of software product, this software product can be stored in a non-volatile memory medium (can be CD-ROM, USB flash disk; Portable hard drive etc.) in; Comprise some instructions with so that computer equipment (can be personal computer, server, the perhaps network equipment etc.) carry out the described method of each embodiment of the present invention.
The above is merely specific embodiment of the present invention, but characteristic of the present invention is not limited thereto, and any people who is familiar with this technology is in field of the present invention, and the variation that can expect easily or modification all should be encompassed in the following claim of the present invention.
