The paper presents a machine vision system for aerial surveillance that can interpret and process data acquired by a UAV on-board infrared camera. System components include noise reduction, feature extraction, classification and decision-making. Decision-making is performed in terms of an alarm signal. The system has been configured for automatic fire(More)
Small unmanned vertical take off and landing vehicles are used to provide the eye-in-the-sky alternative to monitoring and regulating traffic dynamically. Spatial-temporal visual data are collected in real time and they are used to generate traffic-related statistical profiles, serving as inputs to traffic simulation models. Generated profiles, which are(More)
A two module fuzzy logic controller that also includes a separate error calculating box is derived for autonomous navigation and control of small manned- unmanned aerial vehicles demonstrating ability to fly through specified waypoints in a 3-D environment repeatedly, perform trajectory tracking, and, duplicate/follow another vehicle's trajectory. A MATLAB(More)
Alternative designs of a simple, low cost, effective vision system suitable for small, portable, unmanned vertical take off and landing (VTOL) vehicle based surveillance and landmark recognition are presented. Designs depend mainly on two critical constraints: aerial vehicle payload limitations and power supply limitations; both constraints affect on-board(More)
This paper presents a low cost, high powered onboard processing system for miniature unmanned vehicles (UVs), especially unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs). Such vehicles have shown great potential due to their compact size, high maneuverability and high payload-to-size ratio. The proposed on-board processing system differs(More)
In this work we address the problem of object tracking in a largely unknown dynamic environment under the additional constraint of real-time operation and limited computational power. The main design directives remain that of real time execution and low price, high availability components. It is in a sense an investigation for the minimum required hardware(More)
This paper presents a system architecture for an integrated airborne surveillance system that allows Unmanned Aerial Vehicles (UAVs) to serve as autonomous sensing platforms. The proposed architecture consists of the communications, autonomous navigation and machine vision modules enabling the UAV to move into targeted locations, acquire and evaluate(More)
Abstract—In this paper we present the design and implementation of our Small Sized League RoboCup Team – Eagle Knights. We explain the three main components of our architecture: Vision System, AI System and Robots. Each element is an independent entity. The explanation focuses on the improvements made to our fourth generation of robots and how these changes(More)
