摘　　要：在对人体特殊动作进行三维动画重建时,三维动画建模环境中容易产生干扰,导致渲染与建模过程误差较大.提出一种人体特殊动作三维动画建模与渲染方法改进方法,构建人体三维人体骨架模型,依据三维模型和二维动作图像上的线对应关系.通过透视投影关系及人体骨骼的比例关系,对模型中不同三维特征点坐标进行动画重构,并完成高精度渲染.实验结果表明,所提方法具有很高的三维建模精度,效果改进明显.In the special action to the human body 3 d reconstruction, the three dimensional animation modeling environment prone to interference, lead to error rendering and modeling process. Put forward a kind of special body movement to the three dimensional animation modeling and rendering method improvement, building three- dimensional human body skeleton model, based on 3 d models and 2 d images corresponding relationship of the lines, and the camera calibration. Through the perspective projection relationship and the proportion of the human body skeleton, the model of different 3 d reconstruct animated feature point coordinate, and completes the high precision rendering. The experimental results show that the proposed method possesses high precision of 3 d modeling, improve the effect.
