EventVGGT framework enhances depth estimation using cross-modal distillation

Researchers have developed EventVGGT, a novel framework for event-based monocular depth estimation that addresses the scarcity of dense depth annotations. This approach leverages cross-modal distillation from Vision Foundation Models (VFMs) by treating event streams as coherent video sequences, thereby capturing temporal continuity and priors. The framework employs a tri-level distillation strategy, including cross-modal feature mixture, spatio-temporal feature distillation, and temporal consistency distillation, to improve depth prediction accuracy and temporal consistency. Experiments show EventVGGT significantly outperforms existing methods, reducing absolute mean depth error at 30m by over 53% on the EventScape dataset and demonstrating robust zero-shot generalization.
