Density grid . In this model each voxel is assumed to have a continuous density, corresponding to the probability the voxel would block a sensor beam. We use the formulation from [ 34 ], where we track the Beta parameters t ijk and t ijk, with a uniform prior 0 ijk = 0 ijk = 1 for all (i;j;k ). The update for each voxel affected by the ...

In addition to the projection, we add a voxel pooling layer that enables handling a variable number of RGB views associ-ated with a 3D chunk; the pooling is performed on a per ...

The voxel size is comparably larger than previous works on 3D voxel deep learning, which is for our future research on high resolution 3D reconstruction. In this work, we still target on dealing
