5. Scalability: The technology can be scaled across different drone models and sizes, making it suitable for diverse use cases.

How Drone Autonomous Visual SLAM Works in Practice

Visual SLAM operates through a series of interconnected processes:

1. Feature Detection: The drone’s camera captures images of the environment, identifying key features such as edges, corners, and textures.

2. Feature Matching: These features are matched across consecutive frames to track changes in the environment and the drone’s movement.

3. Pose Estimation: Using the matched features, the system calculates the drone’s position and orientation relative to the environment.

4. Map Building: As the drone moves, it constructs a 3D map of its surroundings, which is continuously updated.

5. Loop Closure: To ensure accuracy, Visual SLAM detects when the drone revisits a previously mapped area, correcting any drift in the map.

6. Obstacle Avoidance: Advanced algorithms enable the drone to identify and avoid obstacles in real-time, ensuring safe navigation.
