Fast estimation of fundamental matrix based on stripe constraints

In order to improve the performance of estimating the fundamental matrix, a key problem arising in stereo vision, a novel method based on stripe constraints is presented. In contrast to traditional methods based on algebraic least-square algorithms, the proposed approach aims to minimize a cost function that is derived from the minimum radius of the Hough transform. In a structured-light system with a particular stripe code pattern, there are linear constraints that the points with the same code are on the same surface. Using the Hough transform, the pixels with the same code map to the Hough space, and the radius of the intersections can be defined as the evaluation function in the optimization progress. The global optimum solution of the fundamental matrix can be estimated using a Levenberg- Marquardt optimization iterative process based on the Hough transform radius. Results illustrate the validity of this algorithm, and prove that this method can obtain good performance with high efficiency.

记得几年前，有一次走进朋友的宿舍，里面的电脑之多真的吓了我一跳，六人的大房间里面居然放满了六台电脑，一齐在联机玩星际，爽得不亦乐乎！除了电脑之多，有如蜘蛛网一样错综复杂的网络连线同样令我吃惊，但并非讨大庆。而是羡慕。

职业教育新型活页式教材建设的原则与路径——以建筑施工图识读为例

新型活页式教材建设应与课程改革同时进行,基于职业岗位能力重构模块化课程体系,职业专项能力遴选教材内容,典型工作任务开发学习情境,工作过程转化学习任务、设计活页式结构,根据任务实施活页确定教学活动,通过教学活动选择教学方法。活页式结构基本模式为学习目标活页、任务工单活页、任务实施活页、考核评价活页、理论知识活页、归纳总结活页。教材的呈现方式应多样化、可视化、立体化,并配以信息化手段拓展纸质教材的空间。
