Abstract:

This report presents a comprehensive pipeline for the autonomous visual inspection of bridges using drones. It details the architecture of a vision-based autonomous flight stack designed for operation without GPS, alongside the design of the custom drone prototype. The system’s performance is validated through three flight tests, including deployments at two real-world bridge sites, demonstrating the pipeline’s capability to autonomously navigate complex GPS-denied environments and acquire high-quality inspection data.
