目前医学图像三维体绘制主要采用以下几中方法:光线投射算法(Ray―casting)、抛雪球算法(Splatting)和错切一变形算法(Shear warp) 三维纹理.本文只着重讲解第一种方法的实现原理及部分算法

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

这个文档虽然没有源代码，但是里面有一些关于复杂网络的重要资料，比源代码本身更具有代表意义。-Although this document is not the source code, but there are some on the complex network of important information than the source code itself, on behalf of more significance.
