This paper introduces an affine invariant of trapezia, and the explicit constraint equation between the intrinsic matrix of a camera and the similarity invariants of a trapezium are established using the affine invariant. By this constraint, the inner parameters, motion parameters of the cameras and the similarity invariants of trapezia can be linearly determined using some prior knowledge on the cameras or the trapezia. The proposed algorithms have wide applicability since parallel lines are not rare in many scenes. Experimental results validate the proposed approaches. This work presents a unifying framework based on the parallelism constraint, and the previous methods based on the parallelograms or the parallelepipeds can be integrated into this framework.
Key words: invariant parallelism constraint camera calibration 3D reconstruction

虚拟化安全综述――虚拟化是数据中心的流行技术,它起源于20世纪60年代。它是把昂贵的计算机资源的利用最大化的方式。典型的服务器运行至少40 利用率,虚拟化可以更有效地利用技术资源,并节约固定费用。虚拟化的最大优势是,它允许管理员从中央区域为个人电脑和客户设备提供软件。虚拟化不需要管理员对一般任务进行分别考虑。服务器的关机可以带动多用户的关机。-Virtualization Security Review- virtualization is a popular data center technology, which originated in the 20th century, 60 years. It is to expensive computer resources to maximize the utilization of way. The typical server is running at least 40 utilization, virtualization can be more effective use of technology resources, and save fixed costs. The biggest advantage of virtualization is that it allows administrators from the central region for personal computers and client devices software. Virtualization does not require the administrator of the general tasks considered separately. Server shutdown can foster the multi-user shutdown.
