DAEJEON, Dec. 12 (Korea Bizwire) – South Korean researchers have developed drone technology capable of conducting search operations in forests and valleys where GPS signals are unavailable, the Electronics and Telecommunications Research Institute (ETRI) announced on December 11.
The innovative system applies simultaneous localization and mapping (SLAM) technology – commonly used in autonomous robots – to enable drones to independently recognize their surroundings and plan routes. SLAM allows the drones to navigate without relying on GPS signals.
The system employs drones equipped with electro-optical and infrared (EO/IR) cameras that autonomously fly through designated search areas. The collected footage is transmitted to a mobile control system, which uses deep learning to locate missing persons.
The technology also includes sophisticated 3D point cloud reconstruction capabilities that can precisely map complex, unstructured forest environments and highlight areas where missing persons are likely to be found.
ETRI conducted autonomous flight demonstration tests last month at Jaundae Pine Tree Park, simulating real search conditions. The tests, performed on November 6, involved three drones and were attended by the Gyeongnam Police Department’s drone operations team, Korean National Police University representatives, and industry professionals.
The research team plans to incorporate feedback from the Gyeongnam Police drone operations team to refine the system, with development scheduled for completion by 2027.
“This autonomous drone technology for locating missing persons will help secure the critical golden time for survival,” said Cha Ji-hoon, head of ETRI’s Autonomous Flight Research Laboratory.
“The technology can be applied across various public safety and defense sectors, including military reconnaissance, natural disaster rescue operations, and monitoring illegal activities in forest protection.”
