PTT: Point-Track-Transformer Module for 3D Single Object Tracking in Point Clouds

Understand

3D single object tracking is a key issue for robotics.

• In this paper, we propose a transformer module called Point-Track-Transformer (PTT) for point cloud-based 3D single object tracking.
• PTT module contains three blocks for feature embedding, position encoding, and self-attention feature computation.
• Feature embedding aims to place features closer in the embedding space if they have similar semantic information.
