摘　　要：由于影视动漫作品要有适合的场景,需要对三维动漫场景进行实时漫游。采用传统的方法进行场景实时漫游时,场景信息描述不直观,且三维动漫场景特征多样,导致实时漫游局限性大、耗时长的问题。提出基于视点纠正的三维动漫场景实时漫游方法,先以动漫场景所表示的三维空间为观察目标,对三维图像轮廓进行提取,并对动漫场景重叠区域进行融合处理,通过映射关系对以视点为中心的三维区域进行实时校正,计算三维虚拟空间全景图每一个像素,将照相机坐标系下坐标按透视投影成像规律变换为照相机视平面上坐标,获取新动漫场景视图的像素坐标,以此为依据完成对三维动漫场景实时漫游。仿真结果证明,所提方法实时漫游精确度高,可以确保动漫场景构建的合理性。This article proposes a method for real time roaming of 3D animation scene based on viewpoint correc- tive. Firstly, the author used 3D space of animation scene as observation goal and extracted 3D picture contour, then fused animation scene overlapping region. The 3D area was corrected as center of viewpoint by mapping relation in re- al time and each pixel of 3D virtual apace panorama was calculated. Moreover, the research conversed coordinate un- der camera coordinate system to camera plane coordinate according to perspective projection imaging rule. Experiment simulation results show that above method has high accuracy of real-time roaming and can insure rationality of anima- tion scene building.
