Tracking and imaging humans on heterogeneous infrared sensor arrays for tactical applications

Abstract

We recently implemented a heterogeneous network of infrared motion detectors and an infrared camera for the detection, localization, tracking, and identification of human targets. The network integrates dense deployments of low cost motion sensors for target tracking with sparse deployments of image sensors for target registration. Such networks can be used in tactical applications for local and distributed perimeter and site security. Rapid deployments for crisis management may be of particular interest. This paper focuses particularly on the need for applications that deal with relatively dense and complex source fields such as crowds move through sensor spaces.

Fault-tolerant sensor integration for micro flow-sensor arrays and networks

“…In this context, a micro flow-sensor array refers to a group of micro flow-sensors of the same type placed close together to measure the same variable of interest. Another possibility is to combine different types of sensors to measure different variables in the same array (Feller et al, 2002;Halkyard, 2003;Xu, Chiu, Jiang, Lin, & Tai, 2005). Different groups of micro flow-sensor arrays can be distributed widely and selectively in the flow environment to form a micro flow-sensor network.…”

A Lower Error Arithmetic of Data Fusion

“…Distributed sensor network becomes an increasing popular research field [1], [2], [3], [4]. Though sensor network is feasible in theory and economic, but a lot of problems must be solved to acquire accurate information efficiently [5], [6], [7].…”

Sensor network assisted teleoperation

“…The popularity of sensor networks stems from the broad range of potential applications [1]- [5]. These range from space exploration to remote information gathering or monitoring [1]- [6].…”
