HiPR framework improves camera-LiDAR 3D occupancy prediction with height-guided projection

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced HiPR, a novel framework for camera-LiDAR occupancy prediction that addresses limitations in traditional 2D-to-3D view transformations. HiPR utilizes a height-guided projection reparameterization by encoding LiDAR data into a BEV height map to adaptively adjust the projection space. This method redistributes projected points into more geometrically relevant regions and masks invalid height map data. Additionally, a progressive height conditioning strategy is employed to stabilize training with noisy LiDAR-derived heights, leading to state-of-the-art performance with real-time inference capabilities.
