PillarTrack: A Pillar-based Transformer Network for Efficient and Accurate 3D Single Object Tracking on Point Clouds

PillarTrack is a pillar-based 3D single object tracking framework that improves tracking performance while enhancing inference speed. It introduces a Pyramid-type Encoding Pillar Feature Encoder (PE-PFE) and a modality-aware Transformer-based backbone to effectively capture the geometric information in point clouds.
