VANGUARD: Vehicle-Anchored Ground Sample Distance Estimation for UAVs in GPS-Denied Environments
Researchers developed VANGUARD, a deterministic tool that helps autonomous drones estimate ground sample distance in GPS-denied environments by using vehicles as reference points. The system addresses critical safety issues with AI vision models that showed over 50% errors in spatial scale estimation, achieving 6.87% median error on benchmark tests.
