ORBSLAM3 Integration on BD Spot

ORBSLAM3, known for its robust performance in various scenarios, is adapted to work seamlessly with Spot's onboard sensors cameras. This integration allows Spot to construct a map of its surroundings and localize itself in real-time, even in challenging conditions such as low-light environments or areas with repetitive features. Key features of this integration include: 1. Real-time 6-DoF pose estimation: Enabling Spot to accurately determine its position and orientation in 3D space. 2. Map Generation: Allowing Spot to be aware of the surroundings and know its relative position to the map. 3. Loop closure detection: Improving map consistency and reducing drift over long trajectories.
