Understanding and interacting with complex 3D environments is increasingly important in robotics, virtual reality, and autonomous systems. To address this need, this thesis project aims to develop a system that reconstructs a 3D model of the environment enhanced with semantic features. We project in the 3D model the semantic features extracted using pre-trained 2D foundational models, such as Segment Anything and OpenCLIP. This allows open-vocabulary queries about the environment in natural language that are not restricted by predefined categories or information and without requiring additional training.
The system is tested on real RGB-D data captured from a HoloLens 2 device.
