Paper Abstract

Detection and tracking algorithms for a Hemispherical Optical Sensor Tracker (HOST) are described. The HOST unit provides simultaneous and continuous viewing of a region spanning 360° of azimuth and -7° to zenith in elevation. Maximum likelihood derived, multi-frame detection algorithms are described for use with a stationary HOST surveillance sensor. A multi-target tracking architecture is also described. Due to the nature of the optical system, tracking in Line Of Sight (LOS) angular coordinates is much easier than using pixel coordinate tracking. This in turn provides an opportunity for multi-HOST unit triangulation to obtain 3D position estimates. This paper provides a brief overview of the HOST optical system, describes the multi-frame detection algorithm, the pixel to LOS conversion, and the multi-target track algorithm.
