Automatic Landing of Small Helicopters on 4 DOF Moving Platforms

In this research, an automatic control system is designed for landing of a small helicopter on a 4 DOF moving platform. The platform has three translational and one directional degree of freedom. The controller design approach is based on development of helicopter nonlinear dynamic model into the SDC (State Dependent Coefficient) form and real time solving of state dependent Riccati equation (S...

Statistical Unbiased Background Modeling for Moving Platforms

Statistical background modeling is a standard technique for the detection of moving objects in a static scene. Nevertheless, the stateof-the-art approaches have several lacks for short sequences or quasi-stationary scenes. Quasi-static means that the ego-motion of the sensor is compensated by image processing. Our focus of attention goes back to the modeling of the pixel process, as it was intr...

Robust Multi-Person Tracking from Moving Platforms

In this paper, we address the problem of multi-person tracking in busy pedestrian zones, using a stereo rig mounted on a mobile platform. The complexity of the problem calls for an integrated solution, which extracts as much visual information as possible and combines it through cognitive feedback. We propose such an approach, which jointly estimates camera position, stereo depth, object detect...

Challenges and Prospects of European Railways

In the present paper, challenges and prospects of the European railways, along with a proposal for a new strategy policy and specific measures are presented. The declining course of European railways concerning traffic and revenues is first analyzed. Conditions to introduce intra - modal competition are surveyed, among them separation of infrastructure fro...
