https://leijiezhang001.github.io/paper-reading-Cylinder3D/ 其实Cylinder这种表示很早就有了,3D sparse Convolution也早就有了。而发现柱坐标的voxel和普通三维栅格的表示相同,都可以用3D sparse Convolution做特征提取这个问题就很妙。 本文的效果也许可以再次证明,sparse convolution的特征提取效果可能要优于point-base...
Thermo graphic studies of the cylinder demonstrate that a constant and uniform temperature around the injection nozzle produces more precise and consistent end pieces. Cylinder Heater Core: temperature is uniform all around the perimeter. Block Heater: You can see how the white cartridge heater ...

受ACNet的启发,Cylinder3D使用了不对称3D卷积构造残差块。以Car 和Motorcycle为例,下图展示了作用于圆柱体素的不对称残差块中的3D卷积: 不对称的残差块很好地匹配目标(汽车、卡车、公共汽车、摩托车等立方体物体)的点分布,也节省了计算量和内存开销。 Cylinder3D用不对称残差块设计下采样块和上采样块...

目前主流的激光分割的方法通常将点云投影到2D空间,然后利用2D卷积进行处理,这必定会丧失3D的拓扑与几何特征,一种有效的弥补则是采用3D体素化与3D卷积网络,然而在室外场景的点云数据下效果一般,其中很重要的因素就是稀疏性与变化的点密度。因此本文提出了一种用于室外点云分割的新构架,使用圆柱形划分与非对称3D卷积网...
The flow around a circular cylinder with a low aspect ratio (L/D=4.8) and a high blockage coefficient (D/H=0.208) is investigated. This confined environment is used in order to allow direct comparisons with realisable 3D Navier-Stokes computations avoiding 'infinite' conditions. The flow is ...
2020-11 We preliminarily release the Cylinder3D--v0.1, supporting the LiDAR semantic segmentation on SemanticKITTI and nuScenes. 2020-11 Our work achieves the 1st place in the leaderboard of SemanticKITTI semantic segmentation (until CVPR2021 DDL, still rank 1st in term of Accuracy now), and ba...
