摘要: 针对当前虚拟摄影棚系统前背景匹配算法计算量大、延时长、成本高的缺点,设计并实现了一种快速的符合人眼视觉特性的匹配算法。该算法基于虚拟摄影棚前背景匹配原理及摄像机成像原理,依照人眼视觉系统的视觉惰性、眼球平滑跟随运动及视觉美学相关知识,采用开发桌面控制软件同时控制摄像机与背景的方式来实现。

Abstract: The traditional foreground/background matching algorithm in virtual studio system has many disadvantages such as huge amount of calculations,long time-lapse,high cost and so on.To solve the problems,this paper proposed a fast algorithm by the idea of human visual properties.The algorithm was based on the elements of foreground/background matching,camera imaging,vision inertia,smooth pursuit eye movement and visual aesthetics.And it was implemented by developing desktop control software,to control the camera and the background at the same time.
