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

Introduction data structure#2

今天，64位计算正在逐步取代32位计算，并且，这个转换的过程会对当前软件的形式带来巨大的冲击。其中，转换需要移植相关的应用程序及重写系统软件，这当中还包括操作系统等等。在本文中，将主要探讨64位软件世界中的主角--64位Windows及64位的通用语言运行时库（CLR）的结构，另外，还将涉及移植到64位平台的种种有利之处。-Today, the 64-bit computing is gradually replaced by 32-bit computing, and that this process of conversion software on the current form of heavy blows. Among them, the conversion needs of transplant-related applications and rewrite the system software, which of them, including the operating system and so on. In this article, will be focused on the 64-bit software in the world of the protagonist 64 Windows and 64-bit common language runtime (CLR) of the structure, will also be involved in transplanted into 64-bit platform for all sorts of advantages.
