FlowNet3D++: Geometric Losses For Deep Scene Flow Estimation

WebAug 16, 2024 · 点云的 Scene Flow 与 Semantic 一样是一个较低层的信息，通过 Point-Wise Semantic 信息可以作物体级别的检测，这种方式有很高的召回率，且超参数较少。同样，通过 Point-Wise Scene Flow 作目标级别的运动估计(当然也可作物体点级别聚类检测的线索)，也会非常鲁棒。本文[1] 将点级别/Voxel 级别的 Scene Flow 与 3D ... 动态环境中点的三维运动信息被称为场景流。文章提出了一种新的深度神经网络FlowNet3D用于从点云获得场景流。网络同时学习点云的深度层次特征（deep hierarchical features）和代表点的运动的flow embeddings特征。论文使用FlyingThings3D数据集和KITTI的激光雷达扫描数据进行实验。 See more bully carnival tickets cheats
