UniVLG introduces a pioneering architecture that unifies 2D and 3D vision-language understanding, addressing the critical limitation of 3D data scarcity in embodied AI systems.

• Leverages pre-trained 2D model weights as initialization for 3D understanding
• Employs a novel language-conditioned mask decoder shared across dimensions
• Trains simultaneously on both 2D and 3D vision-language datasets
• Enables more robust perception for robotics and embodied AI applications

This engineering breakthrough creates a foundation for developing more capable autonomous systems that can understand both 2D imagery and 3D environments through natural language interaction.
