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.

ViPFormer: Efficient Vision-and-Pointcloud Transformer for Unsupervised Pointcloud Understanding

1 code implementation25 Mar 2023 Hongyu Sun, Yongcai Wang, Xudong Cai, Xuewei Bai, Deying Li

For example, the image branch in CrossPoint is $\sim$8. 3x heavier than the point cloud branch leading to higher complexity and latency.
