Surveillance Routing with a Minimum Number of Drones

In recent years, drones have been expected to be utilized for facility patrol surveillance. This is because drones have cameras, and they can be operated remotely. There have been studies for surveillance routing by multi-drones in the past. These studies coordinated drones with ground vehicles, aiming to minimize the total patrol time. This paper presents the method to find surveillance routing with a minimum number of drones. Experiments show that as surveillance coverage extends, minimum number of drones increases.
