Loading...Introduction to Autonomous Drone Navigation
When I first started working on autonomous drone navigation systems, I realized that most documentation skips the hard part - integrating computer vision algorithms for obstacle detection and avoidance. Last quarter, our team discovered that using PX4 1.13, ArduPilot 4.3, and OpenCV 5.0 can significantly improve the navigation capabilities of drones. However, the real challenge lies in choosing the right computer vision algorithm for obstacle detection.
Comparative Analysis of Computer Vision Algorithms
I tested three approaches:
- Edge Detection: Using OpenCV's Canny edge detection algorithm to identify obstacles. However, this approach failed to detect obstacles in low-light conditions.
- Depth Estimation: Utilizing OpenCV's stereo vision to estimate depth. Although this method provided better results, it was computationally expensive and required significant processing power.
- Semantic Segmentation: Implementing a deep learning-based approach using OpenCV's DNN module.
