Drone visual navigation module

The N200M Visual Navigation Module (VIO) is an integrated solution designed for drone environmental perception and positioning needs. It comprises an AI main board, USB camera, and laser rangefinder. The module's core functionality fuses visual, laser, and IMU data from the flight controller to provide drones with real-time, precise positioning navigation, environmental awareness, and assisted obstacle avoidance capabilities. This addresses the limitations of traditional GPS-dependent drones, such as scenarios with GPS interference or weak signals. Core components and key features include:

(1) AI Main board (Core Computing Unit)

Equipped with a high-performance computing main controller, it processes visual data from the USB camera and inertial data from the flight controller's IMU (Inertial Measurement Unit). Through algorithms, it enables real-time attitude calculation and position localization for the drone.

(2) High-Definition Camera (Visual Perception Unit)

Provides high-resolution visual input, capturing environmental imagery to furnish the algorithm with foundational image data for feature point extraction and motion estimation.

(3) Laser Rangefinder (Auxiliary Perception Unit)

Assists the drone in achieving precise altitude measurement, obstacle distance detection, and terrain following, compensating for the limitations of visual systems in low-light or texture less environments.
