Abstract
The present invention proposes a kind of method that animation is directly automatically generated from static human model, comprise the following steps (1) and automatically extract and identify first 5 characteristic points for being located at human limb and crown end, using characteristic point as starting point, the geodesic center line such as computation model；(2) gained knowledge on centerline according to anthropological measuring, determine the apparent position of artis；(3) and then according to the bone information that skeleton rigid motion feature and exercise data file provide, carry out artis and be accurately positioned；(4) vertex weights calculated by thermodynamics diffusion equation again finally realize the bone of extraction using the method that local coordinate frame aligns and match with exercise data, and skin generation human body animation driven with exercise data the experimental results showed that.The present invention has the characteristics that unrelated with model attitude, full-automatic, generation animation effect is good without manually participating in.
Description
Technical field
The invention belongs to directly automatically generate animation field from static human model.
Background technology
The human body animation of computer generation is widely used in fields such as game, film advertisement, virtual realities,
In it is the most commonly used be skeleton cartoon, it drives skin deformation to generate animation by bone, have data volume is small, it is simple to calculate,
It is easily achieved the advantages that hardware-accelerated.Human body surface model, human body movement data can be respectively by spatial digitizer, fortune at present
The dynamic instrument that captures easily obtains.But bone modeling therein and binding, weight setting need the personnel by specialized training
It realizes by hand, it is very time-consuming and loaded down with trivial details；In addition, or bone extraction algorithm is confined to the pass of standard posture or extraction at present
Node is not accurate enough, can not meet animation needs.
The content of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of side that animation is directly automatically generated from static human model
Method without manually participating in, has the characteristics that unrelated with model attitude, full-automatic, generation animation effect is good.
The technical proposal of the invention is realized in this way：A kind of side that animation is directly automatically generated from static human model
Method, including
(1) automatically extract and identify first 5 characteristic points positioned at human limb and crown end, using characteristic point for
The geodesic center line such as point, computation model；
(2) gained knowledge on centerline according to anthropological measuring, determine the apparent position of artis；
(3) and then according to the bone information that skeleton rigid motion feature and exercise data file provide, joint is carried out
Point is accurately positioned；
(4) vertex weights are calculated by thermodynamics diffusion equation again finally the bone of extraction is alignd using local coordinate frame
Method realization match with exercise data, and with exercise data drive skin generation human body animation the experimental results showed that.
Further, harmonic function algorithm can be used in the extraction of the center line or geodesic distance calculates the side of isopleth
Method.
Further, the search range of the joint on centerline is [ri-a(ri-ri-1), ri+a(ri+1-ri)],
Middle i represents i-th of joint, riRepresent i-th of joint jiValue on geodetic survey model, a are 0.5.
Compared with prior art, the present invention has the following advantages：
1) automatically, without manual intervention, on the basis of manikin and exercise data are provided, you can automatically generate human body
Animation；
2) posture is unrelated, and context of methods does not limit human body attitude, suitable for various non-standard postures, with existing method
Compared to better versatility；
3) high efficiency can quickly generate human body animation.
Specific embodiment
Technical scheme is clearly and completely described below in conjunction with embodiment, it is clear that described reality
It is only part of the embodiment of the present invention to apply example, instead of all the embodiments.Based on the embodiments of the present invention, this field is general
Logical technical staff all other embodiments obtained without creative efforts belong to what the present invention protected
Scope.
A kind of method that animation is directly automatically generated from static human model, including
(1) automatically extract and identify first 5 characteristic points positioned at human limb and crown end, using characteristic point for
The geodesic center line such as point, computation model；
(2) gained knowledge on centerline according to anthropological measuring, determine the apparent position of artis；
(3) and then according to the bone information that skeleton rigid motion feature and exercise data file provide, joint is carried out
Point is accurately positioned；
(4) vertex weights are calculated by thermodynamics diffusion equation again finally the bone of extraction is alignd using local coordinate frame
Method realization match with exercise data, and with exercise data drive skin generation human body animation the experimental results showed that.
In above-described embodiment, harmonic function algorithm can be used for the extraction of the center line or geodesic distance calculates isopleth
Method.
In above-described embodiment, the search range of the joint on centerline is [ri-a(ri-ri-1), ri+a(ri+1-
ri)], wherein i represents i-th of joint, riRepresent i-th of joint jiValue on geodetic survey model, a are 0.5.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modifications, equivalent replacements and improvements are made should all be included in the protection scope of the present invention god.
