Cooperative Minimum Time Surveillance With Multiple Ground Vehicles
David A. Anisi, Petter Ögren, Xiaoming Hu · IEEE Transactions on Automatic Control · 2010
In this paper, we formulate and solve two different minimum time problems related to unmanned ground vehicle (UGV) surveillance. The first problem is the following. Given a set of surveillance UGVs and a polyhedral area, find waypoint-paths for all UGVs such that every point of the area is visible from a point on a path and such that the time for executing the search in parallel is minimized. Here, the sensors' field of view are assumed to have a limited coverage range and be occluded by the obstacles.
