摘　　要：手机短信3D动画自动生成系统,依托于全过程计算机辅助动画自动生成技术,将发送方短信分析理解后自动生成一段对应主题的三维动画并发送给接收方.摄像机是表现动画主题的关键方式,其拍摄的效果好坏直接影响场景动画的表达内容的主题.本文从定性规划和定量规划两个部分,结合手机动画的特点,对系统中摄像机的拍摄方案进行设计.利用本体库对摄像机属性与拍摄方案进行刻画,采用规则推理的方法,针对不同主题的场景,获取其中关键的拍摄目标,并且采取不同的拍摄手法与镜头组合方式,然后将定性描述信息转换为图形学数据进行定量计算与参数赋值,最终实现计算机辅助下摄像机规划的自动生成.Rely on the technique of full life cycle computer aided animation generation, in the 3D animation auto-generation system of short message, short message from the sender is translated to an animation and presented to the recipient, with the aid of computer. Camera is the key way to show the content of 3D animation and the effectiveness of the camera directly affects the expression of the content of the animation. In this paper, combining with the characteristics of mobile phone animation system, we design the scheme of camera shooting through qualitative planning and quantitative planning. Firstly, we describe the camera attributes and shooting schemes by ontology. With the method of logical reasoning, we get main targets from scenes of different topics and take different shooting styles and combinations of camera lens. Then, the qualitative descriptions of cameras are converted into graph data for quantitative calculation and parameter assignment. And finally we achieve the auto-generation of camera planning.
