摘要
针对在Unity3D中以第一人称视觉虚拟漫游的摄像机视点标定的不确定性和经验性，提出基于人体美学黄金分割理论的胶囊体摄像机视点标定算法。首先通过黄金比例关系的系数法确定头部在胶囊体上的高度范围，然后再根据面部黄金分割律“三庭五眼”标定眉间的位置，从而达到摄像机视点精确定位的目的。通过不同高度胶囊体摄像机视点进行实验，使用该方法拍摄到的场景更符合人在现实中所看的场景，使用户更能沉浸场景中，取得较为满意的定位效果；也为摄像机视点定位操作提供一套可依据的方法。
Abstract
Being different from the uncertainty of camera shooting viewpoints of targets in virtual wandering of the first person in the Unity3D and the empiricism of common photographers, proposes a demarcating method for shooting viewpoints of target capsules based on the golden cut theory of human body aesthetics. This method achieves the accurate positioning of the shooting viewpoints through the altitude ranges sourced from the coefficient of the golden ratio of human body and the right position between the eyebrows based on the golden cut theory of human face division named “San Ting Wu Yan” in Chinese. Through experiments of the viewpoints chosen on different heights of the target capsules, this method can gain mappings better like the real situations and make people better immerse in the photographing and reach a more satisfactory positioning effectiveness. Furthermore, this method can provide a reliable way for the operations of positioning in camera shooting viewpoints.
