摘　　要：近年来,随着计算机图形学特别是计算机动画研究与应用的飞速发展,科幻电影中出现了大量的机甲身体和外化骨骼等数字化身体.这种对于身体的所指现象,逐渐形成了一套独特的视觉符号.结合人工智能的交叉性和数字算法,如何从基于真实演员的自然身体转向为数字化身体,并在此基础上保持其行为和情感的自然性,从而形成数字化身体的行为和情感的自然融合与互动,已经成为计算机图形学研究与应用的又一个挑战.文中从具身认知学的角度出发,以一系列科幻电影中的数字化人物为例,将身体图式作为理解数字化身体的行为与情感自然融合的关键所在,将身体图式分类为数字身体、复合身体和人造身体,从身体图式到内在感知以及科幻电影中身体图式的空间转向,在理论上对空间转化与互动进行分析.相关研究对今后在科幻电影中如何创造更加人性化的虚拟人物有着积极的作用.In recent years,with the rapid development of computer graphics,especially the research and application of computer animation,a large number of robot body,exoskeleton and other digital bodies have appeared in science fiction films.This refers to the body phenomenon,gradually formed a set of unique visual symbols.Combining the intersection of artificial intelligence and digital algorithm,how to change from the natural body based on real actors to the digital body,and maintain the naturalness of its behaviors and emotions on this basis,thus forming the natural integration and interaction of behaviors and emotions of the digital body,has become another challenge for the research and application of computer graphics.The article from the perspective of cognitive science,with digital characters of science fiction movies,for example,the"body schema"as understanding the behavior of digital body and the key to emotional nature fusion,and theoretically analyze from the inner perception to the space transformation and interaction,which including digital body,compound and artificial body.Related research has a positive effect on how to design more humanized virtual human in science fiction movies in the future.
