考虑到LiDAR点云的稀疏性(即大约90%的体素都没有点),Vote3 Deep使用了投票方案(voting scheme),而SECOND使用了3D SpConv和3D SubSpConv来构建基于3D sparse CNN的骨干网络,用于LiDAR点云中的3D目标检测。 3DBN sparse CNN的设计遵循encoder网络架构或encoder/decoder网络架构。Encoder网络架构会使用足够多的连续的3D...
Compressive holography techniques enabled 3D reconstruction from a single 2D hologram for sparse 3D densities32,33. However, for densely packed specimens, decompressive interference using a forward model is an ill-posed problem34. On the contrary, estimating the local depth information and the optical...
