Abstract
In recent years, small, inexpensive UAV - also known as drone - has made great progress, which brings privacy and security issues. Drone detection is one of the important methods to solve these problems. The main challenges of drone detection are: (1) A drone is very confusing with other flying objects such as a bird, (2) the low-flying UAV occlusion happens very frequent, and (3) the existing surveillance coverage is limited. Camera array can be used for large-scale airspace observation. In this paper, we propose a modular camera array system with audio assistance, which consists of dozens of high-definition cameras and multiple microphones, to monitor drones. It can be mounted on a carrier after reducing the size. The system captures the image and audio information of the surroundings in various directions. The system can integrate the information of multiple sensors, and identify the characteristics of the drone to achieve higher efficiency of drone monitoring.
