【摘要】：近年来,随着立体显示技术的快速发展,立体三维动画在各个领域的应用需求越来越大.然而在立体三维动画制作中,立体效果的调节过程难以控制,容易产生立体感不足或视觉不适等问题.为此,提出一种面向立体动画制作前期的立体效果调整方法.首先分析场景深度、立体图像的视差以及图像立体效果三者之间的关系,生成图像的视差变化梯度图;其次分析视差与观看距离的关系,推导最佳观看效果的视差范围,并在视差变化梯度图上标记出引起观看不适的部分;最后得出立体参数与视差的关系曲线,通过分析虚拟立体摄像机参数变化对视差的影响,辅助动画制作者准确调整立体效果.将文中方法以Maya插件的形式实现,并使用商业动画电影《兔侠传奇2:青黎传说中》的镜头素材进行实验,结果表明,与传统方法相比,该方法准确性好、自动化程度高,能有效地提高立体动画的制作效率.
[Abstract]:In recent years, with the rapid development of stereoscopic display technology, stereo 3D animation needs more and more applications in various fields. However, the adjustment process of stereo effect is difficult to control in the production of three-dimensional animation. Therefore, this paper presents a method of stereo effect adjustment in the early stage of stereoscopic animation production. Firstly, the relationship among scene depth, parallax of stereo image and stereo effect of image is analyzed to generate the gradient map of disparity variation of image; secondly, the relationship between parallax and viewing distance is analyzed, and the range of parallax of the best viewing effect is deduced. Finally, the relationship curve between stereo parameters and parallax is obtained, and the effect of the variation of virtual stereo camera parameters on parallax is analyzed. Assist animation makers to accurately adjust stereoscopic effects. The method in this paper is implemented in the form of Maya plug-in, and the experiment is carried out using the lens material of commercial animation film "Rabbit Legend 2: Qingli Legend". The results show that compared with the traditional method, this method has better accuracy and higher degree of automation. It can effectively improve the production efficiency of three-dimensional animation.
