“…5 Nonimaging target detections and tracking systems have also been designed by coherently fusing large number of fiber optic cables, creating a nonconventional optic to detect bright objects. 6 Conventional imaging systems have been used extensively in intelligence, surveillance, and reconnaissance applications. These systems have typically been based on using two-dimensional (2-D) focal plane arrays.…”

Abstract. This paper presents a proof of concept sensor system based on a linear array of pyroelectric detectors for recognition of moving objects. The utility of this prototype sensor is demonstrated by its use in trail monitoring and perimeter protection applications for classifying humans against animals with object motion transverse to the field of view of the sensor array. Data acquisition using the system was performed under varied terrains and using a wide variety of animals and humans. With the objective of eventually porting the algorithms onto a low resource computational platform, simple signal processing, feature extraction, and classification techniques are used. The object recognition algorithm uses a combination of geometrical and texture features to provide limited insensitivity to range and speed. Analysis of system performance shows its effectiveness in discriminating humans and animals with high classification accuracy.

“…1 That paper concentrated on laboratory tests whose purpose was the characterization and calibration of the Dragonfly optic 2 and its incorporation into a laboratory version of a Dragonfly directional sensor (DDS). The DDS is a very wide-field nonimaging sensor which has the capability to locate and track multiple bright objects against a darker background.…”
