Anisotropic Omnidirectional Imaging System for Remote Surveillance of Devastated Area

Abstract

The Horizontal fixed viewpoints Biconical Paraboloidal:HBP mirror is an anisotropic convex mirror that has inhomogeneous angular resolution about azimuth angle. In this paper, we propose a remote surveillance system with a specially designed HBP mirror system for collecting information of devastated areas. We used a virtual remote surveillance environment for investigating effectiveness of the HBP mirror system compared with conventional omnidirectional imaging systems. From results of object searching experiments, we confirmed that objects can be detected early and with certainty by the HBP mirror system. We also developed a real remote surveillance system for actual surveillance experiments. Through those two types of experiments, we got the results that the HBP mirror system effectively works for remote surveillance.
