CVPR 2023

BEVHeight is a new vision-based 3D object detector specially designed for roadside scenario. BEVHeight surpasses BEVDepth base- line by a margin of 4.85% and 4.43% on DAIR-V2X-I and Rope3D benchmarks under the traditional clean settings, and by 26.88% on robust settings where external camera parameters changes. We hope our work can shed light on studying more effective feature representation on roadside perception.
