CoCam4D: Geometry-Aware Cooperative 4D Perception for Camera-Only Autonomous Driving

CoCam4D is a Bayesian framework for camera-only autonomous driving that models geometric uncertainty in collaborative perception. It employs a VGGT-based network to produce 3D Gaussian scene representations with uncertainty estimates, allowing multiple vehicles to fuse observations without LiDAR. The system introduces Dynamic Object Primitives, a 35‑byte format for efficient C‑V2X communication, and shows significant performance gains over recent vision-only methods on OPV2V+ and DAIR‑V2X‑C benchmarks.

Uncertainty-Aware World Model for Aerial Image-Goal Navigation

Aerial image-goal navigation requires an unmanned aerial vehicle (UAV) to reach a target location specified by a goal image. Existing world-model-based methods rank candidate trajectories using predicted futures, but typically rely on only one or a few point predictions, which is inadequate for large-scale outdoor environments with substantial future-state uncertainty.
