平面扫描(plane sweep)技术主要解决什么问题?其主要步骤? 答:主要解决的就是如何在过滤阶段中尽可能多的淘汰不符合条件的对,从而减少几何计算的计算代价。 Step 1:从左至右移动一条扫描线(例如,垂直于x轴的线),停在R∪S的第一个元素处。这就就是具有最小T.xl值的矩形T,例子为就是矩形R4 。
最近在研究Multi-View Stereo(MVS)的相关工作,MVS包含很多步骤,也有point cloud reconstructions,volumetric reconstructions,depth map reconstructions等各种解决方案。这里只是讨论其中的depth估计的相关算法中构造cost volume的平面扫描(plane sweep)算法。主要是学习经典作MVSNet[1]发现的一些问题以及相关些思考,这里记下。(...
