VOLoc: Visual Place Recognition by Querying Compressed Lidar Map

1 code implementation25 Feb 2024 Xudong Cai, Yongcai Wang, Zhe Huang, Yu Shao, Deying Li

Then the QPC is compressed by the same GPC, and is aggregated into a global descriptor by an attention-based aggregation module, to query the compressed Lidar map in the vector space.

AirBirds: A Large-scale Challenging Dataset for Bird Strike Prevention in Real-world Airports

no code implementations23 Apr 2023 Hongyu Sun, Yongcai Wang, Xudong Cai, Peng Wang, Zhe Huang, Deying Li, Yu Shao, Shuo Wang

To advance the research and practical solutions for bird strike prevention, in this paper, we present a large-scale challenging dataset AirBirds that consists of 118, 312 time-series images, where a total of 409, 967 bounding boxes of flying birds are manually, carefully annotated.

IDLL: Inverse Depth Line based Visual Localization in Challenging Environments

no code implementations23 Apr 2023 Wanting Li, Yu Shao, Yongcai Wang, Shuo Wang, Xuewei Bai, Deying Li

In this paper, we propose Inverse Depth Line Localization(IDLL), which models each extracted line feature using two inverse depth variables exploiting the fact that the projected pixel coordinates on the image plane are rather accurate, which partially restrict the lines.
