【摘要】：伴随着科技的进步,计算机3D图形学、计算机视觉、计算机虚拟现实、计算机数字非线性后期合成等技术的引入,为3D数字电影应用于风光类型影片的发展提供了新的突破,数字3D影片更加立体、直观的影片感受效果使数字3D立体电影在城市宣传片和旅游风光影片中得到迅猛发展,3D数字立体电影使人们的观影感受集视觉、听觉、触觉、嗅觉等综合体验于一体,真正让人们身临其境地体验到3D数字影片的魅力。本文在对数字3D电影制作进行分析的基础上,运用国内外已有风光类型影片的数字3D摄制及2D转3D制作技术,研究3D立体拍摄技术,2D转3D制作技术,以及计算机非线性后期技术在《吉林风光》影片中的应用。本文主要工作如下： 1.分析数字3D立体电影摄制及计算机非线性制作理论基础。包括对3D立体电影的定义、3D立体电影拍摄技术、3D立体电影拍摄原理和3D电影难点、重点技术的分析和论述。 2.研究3D立体摄制技术在《吉林风光》影片中的应用。根据不同场景拍摄制作的3D立体风光影片主要采用立体拍摄技术,包括立体场景的布局,景深、轴间距的设定,摄像机跟踪夹角的设定,变焦与跟焦,光线与色彩的运用等。 3.2D转3D技术要点,重点介绍我们采取的深度图的计算方法。 4.研究3D影片计算机非线性后期制作技术在《吉林风光》中的应用。包括对剧本讨论、概念设计、分镜故事板、粗模、贴图材质、骨骼蒙皮、分镜动画、灯光、3D特效、分层渲染/合成、后期剪辑。其中,后期剪辑是关键步骤。阐述制作过程中遇到的主要问题及解决对策。综上,本文通过对目前3D立体影像拍摄、2D转3D制作技术,后期计算机非线性编辑普遍存在的技术应用问题研究,总结出新的三维立体影像拍摄、后期非线性编辑体系,为社会提供更简便易行的拍摄、后期非线性编辑方式方法,推动我国的三维立体技术的普及,解决当前国内三维立体影像片源少的问题。
[Abstract]:Along with the progress of science and technology, the introduction of computer 3D graphics, computer vision, computer virtual reality, computer digital nonlinear post-synthesis and other technologies has provided a new breakthrough for the application of 3D digital film in the development of scenery film. Digital 3D films are more stereoscopic, intuitive film experience results in the rapid development of digital 3D stereoscopic films in city propaganda and tourist scenery films. 3D 3D 3D films enable people to watch and feel visual, auditory, tactile, visual, auditory, and tactile. Smell and other comprehensive experience in one, really let people experience the charm of 3D digital film. Based on the analysis of the digital 3D film production, this paper studies the 3D to 3D production technology by using the digital 3D filming and 2D to 3D production technology of the domestic and foreign scenery films. And the application of computer nonlinear late technology in Jilin scenery film. The main work of this paper is as follows: 1. The theoretical basis of digital 3D stereoscopic film production and computer nonlinear production is analyzed. This paper includes the definition of 3D stereoscopic film, the principle and difficulty of 3D stereoscopic film shooting, the analysis and discussion of the key technology. 2. This paper studies the application of 3D stereoscopic film in Jilin scenery. According to different scenes, 3D stereoscopic films are mainly made by stereoscopic photography techniques, including the layout of stereo scenes, depth of field, setting of axial spacing, setting of camera tracking angle, zoom and focus. The application of light and color, etc. 3.2D to 3D technical essentials, focus on the depth map we adopted the calculation method. 4. This paper studies the application of 3 D computer nonlinear post production technology in Jilin scenery. Including script discussion, conceptual design, split story board, rough mold, texturing material, bone skin, split mirror animation, lighting 3D special effects, layered rendering / composition, late editing. Among them, post-editing is the key step. This paper expounds the main problems encountered in the process of production and the countermeasures to solve them. In summary, this paper summarizes the new 3D stereo image shooting and nonlinear editing system by studying the current 3D stereo image making technology and the general application of computer nonlinear editing. In order to promote the popularization of 3D stereo technology in our country and solve the problem that there are few sources of 3D stereoscopic images in China, this paper provides a more simple and easy way to shoot, and the method of non-linear editing in the later period.
