摘　　要："多镜头反光式全景视频系统"旨在讨论一种工程上可行的全景视频系统架构,通过将一组同型镜头在同一水平面上环形对称排列,同时对周围360°内环境进行视频采集,并将采集到的多幅视频图像进行时间同步、色彩融合、统一白平衡、透视变换等处理,从而生成完整的高清晰度全景视频。该系统采用特殊的光路设计,使所有镜头光心重合,从而彻底消除视觉盲区和重影区。讨论一种统一白平衡处理方法,较好地解决了相邻图像帧间存在的色彩差异问题。主要讨论"多镜头反光式全景视频系统"的软/硬件系统架构及其相关算法,该软/硬件系统架构及其相关算法已在一台全景摄像机系统样机上实现,能够接近实时地生成环360°的全景视频,表明了该软/硬件系统架构及其相关算法在工程上具有可行性。A panoramic video creating system which has multiple lens arraying in a circle to capture video of surroundings around,and create a high definition panoramic video after some disposal such as time synchronization, uniform white balance, color blending and perspective transformation. This system adopts a special light route to make all lenses optical point superpose to a single point, which eliminates the blind areas and the overlapping areas. The uniform white balance method, which resolves the color difference between the two neighbor frames commendably is discussed, algorithm and system architecture of software and hardware are mainly introduced. The algorithm and system architecture of software and hardware have come true in a panoramic camera with the capability to create a panoramic video of 360 degree around,indicating that they are viable on project.
