What is: PolarNet?

SourcePolarNet: An Improved Grid Representation for Online LiDAR Point Clouds Semantic Segmentation
Data SourceCC BY-SA -

PolarNet is an improved grid representation for online, single-scan LiDAR point clouds. Instead of using common spherical or bird's-eye-view projection, the polar bird's-eye-view representation balances the points across grid cells in a polar coordinate system, indirectly aligning a segmentation network's attention with the long-tailed distribution of the points along the radial axis.
