Exploring Object-Centric Temporal Modeling for Efficient Multi-View 3D Object Detection

Wang, Shihao, Liu, Yingfei, Wang, Tiancai et al.

Understand

In this paper, we propose a long-sequence modeling framework, named StreamPETR, for multi-view 3D object detection.

  • Built upon the sparse query design in the PETR series, we systematically develop an object-centric temporal mechanism.
  • The model is performed in an online manner and the long-term historical information is propagated through object queries frame by frame.
  • Besides, we introduce a motion-aware layer normalization to model the movement of the objects.
