Maintaining visibility of a moving target at a fixed distance: the case of observer bounded speed
R. Murrieta, Alejandro Sarmiento, Sourabh Bhattacharya, Seth Hutchinson · 2004
This work addresses the problem of computing the motions of a robot observer in order to maintain visibility of a moving target at a fixed surveillance distance. In this paper, we deal specifically with the situation in which the observer has bounded velocity. We give necessary conditions for the existence of a surveillance strategy and give an algorithm that generates surveillance strategies.
