然后就发现了 任务:scene flow,其实在2D可能更为人所熟知一些:光流检测,optical flow,也就是输入两帧连续的图片,输出其中一张的每个pixel的运动趋势,NxNx2,其中N为图片大小,2为x,y两个方向上的速度 对应的 3D情况下 则是切换为 输入是两帧连续的点云帧,输出一个点云帧内每个点的运动,Nx3,N为点云帧内点...
已知一个单目相机拍摄的前后两帧图片之间的2D optical flow,如何计算出其对应的3D场景中,每个像素对应的3D点的scene flow ?这篇论文提出了一个基于Optical Expansion的实现方案,通过Optical Expansion以及相机参数等信息,即可将2D Optical Flow “升级” 为3D Scene Flow。文章、源码如下: Upgrading Optical Flow to ...

Scene flow is the three-dimensional motion field of points in the world, just as optical flow is the two-dimensional motion field of points in an image. Any optical flow is simply the projection of the scene flow onto the image plane of a camera. We present a framework for the ...
The optical flow represents the pixel motion of adjacent frames. In contrast, the scene flow is a 3D motion field of the dynamic scene between two frames. Traditional approaches for the estimation of optical flow and scene flow usually leverage the variational technique, which can be solved as ...

3D scene flow estimation aims to jointly recover dense geometry and 3D motion from stereoscopic image sequences, thus generalizes classical disparity and 2D optical flow estimation. To realize its conceptual benefits and overcome limitations of many existing methods, we propose to represent the dynamic...
