COGNIMAP3D processes monocular videos to distinguish static from dynamic elements and builds persistent 3D environmental memories. The framework refines camera poses and achieves superior camera pose estimation, with an Absolute Translation Error of 0.012 on TUM-dynamics, while maintaining competitive depth and 3D reconstruction at 14.32 frames per second.
Key insights
- Emulating human cognitive processes, such as distinguishing dynamic elements and building persistent spatial memory, can enhance the robustness and long-term utility of 3D perception systems.
- Integrating Vision Foundation Models for initial priors with specialized motion separation and memory systems allows for comprehensive dynamic scene understanding without sacrificing efficiency.
- Factor graph optimization, strengthened by high-confidence landmarks from a cognitive memory, effectively improves camera pose consistency in dynamic and re-visited environments.
