This work presents a collaborative unmanned aerial and ground vehicle system which utilizes the aerial vehicle's overhead view to inform the ground vehicle's path planning in real time. The aerial vehicle acquires imagery which is assembled into a orthomosaic and then classified. These terrain classes are used to estimate relative navigation costs for the ground vehicle so energy-efficient path...

In order to test an IVIS (In-Vehicle Information System) in a simulated environment a concept for using CVIS (Cooperative Vehicle-Infrastructure System) based application in a driving simulator is proposed. The system provides the application, an incident warning application, with position data for the simulated vehicle and data regarding the road network. For the test described here, an existi...

This paper presents a new real-time hierarchical (topological/metric) localization system applied to the robust self-location of a vehicle in large-scale urban environments. Our proposal improves the current vehicle navigation systems based only on GPS sensor. It is exclusively based on the information provided by both, a low-cost wideangle stereo camera and a low-cost GPS. A low level metric p...

Abstract: Commercial vehicle operation (CVO) has been a popular application of intelligent transportation systems. Location determination and route tracing of an on-board unit (OBU) in a vehicle is an important capability for CVO. However, large location errors from global positioning system (GPS) receivers may occur in cities that shield GPS signals. Therefore, a highly efficient mobile positi...

Vehicle self-localization is an essential requirement for many of the safety applications envisioned for vehicular networks. The mathematical models used in current vehicular localization schemes focus on modeling the localization error itself, and overlook the potential correlation between successive localization measurement errors. In this paper, we first investigate the existence of correlat...

There are an increasing number of applications requiring precise relative position and clock offset information. The Global Positioning System has demonstrated precise and drift free position and timing information using CodeDivision-Multiple-Access (CDMA) spread spectrum technology. This technology is widely used and relatively inexpensive, making it attractive in applications beyond the scope...

[1] ABSTRACT The International Aerial Robotics Competition (IARC) is designed for colleges and universities to compete in the design and construction of an autonomous aerial vehicle. Pima Community College is being represented by the Unmanned Aerial Vehicle (UAV) Club. The UAV Club has designed a primary vehicle and a drop vehicle that will be used in the competition. They were designed with au...

Detection, recognition, and positioning of road signs are critical components of a roadway asset management system. In this research, a stereo visionbased system is developed to conduct automated road sign inventory. The system in real time integrates and synchronizes the data streams from multiple sensors of high-resolution cameras, Differential Global Positioning System receivers, Distance Me...

In this paper, we propose a cooperative energy-efficient localization framework (CELF) for power saving in vehicular long-thin networks (VLTNs) with fleet cyclists using smart phones along a common cycling route. As cyclists upload their position data and download global fleet information, all power-consuming GPS receivers have to be turned on for obtaining their current locations. To minimize ...

Well-developed individual and collaborative skills, such as dribbling the ball, positioning, and passing are required for a team of robots to be successful against an opponent team in a robot soccer scenario. This paper proposes an approach to individual and collaborative skill learning, where the robots are modeled as Braitenberg vehicles, and the required skills are implemented as combination...
