tl;dr: Vehicle reID with fisheye surround cameras.

Overall impression

Another practical work from Zongmu. The tracking

Key ideas

  • single camera reID
    • This should be largely tracking. --> why this is called ReID?
    • SiamRPN++ model for single camera tracking
  • multi camera reID
    • BDBnet model (batch dropblock, ICCV 2019, SOTA for pedestrian ReID)
    • association rule based on physics and geometry to only perform vehicle ReID in overlapping FoV
    • feature distance and geometry constraint distance

Technical details

Notes

  • Talk at CVPR 2020
  • I feel that only the physical constraint will already do very good cross camera reID of the same vehicle. Do we really need reID module?
