This invention describes a specialized, low-cost drone designed to operate without GPS in dangerous areas. It uses its own imaging and processing to autonomously collect data, like surveying damage, and can identify when it's out of communication range with a base station by tracking its position on an internal 3D map.
Why it matters: Since 2023, significant progress in visual SLAM algorithms and on-device AI processing has made robust, low-cost, GPS-denied navigation and real-time 3D mapping more achievable. This could simplify the core technical challenges of the drone's autonomous operation and data analysis.
