Asynchronous switching decentralized controllers for spacecraft formations
(2004)IFAC Proceedings Volumes ~ Automatic control in aerospace 2004The spacecraft formation control design problem is specified in terms of the relative positions of all spacecraft in the formation. Each spacecraft controller requires only a subset of the formation relative positions, and can switch asynchronously between many such information subsets, allowing it to replace measured information by information communicated from other spacecraft. A two dimensional simulation example is used to illustrate ...Conference Paper -
How to Evaluate the Quality of Airborne Laser-Scanning Data
(2004)International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesThe discussion on the quality of digital elevation models form airborne laser scanner was dominated by the proof of vertical and horizontal accuracy. If the accuracy criteria were verified by ground control points, the evidence of high quality was produced. Based on experiences in projects for the Swiss Federal Office of Topography and according to the lidar requirements formulated by the US American ...Conference Paper -
Character Reconstruction and Animation from Monocular Sequence of Images
(2004)International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesIn this paper we present different methods for the calibration and orientation of monocular image sequences and the 3Dreconstruction of human characters. Three different situations are considered: a static character imaged with a moving camera, amoving character imaged with a fix camera and a moving character imaged with a moving camera. A self-acquired sequence is usedin the first case while in the other ...Conference Paper -
Robust Model Predictive Control of Constrained Linear Systems
(2004)Proceedings of the 2004 American Control ConferenceLinear matrix inequality (LMI) based optimization methods are applied to the problem of designing a model predictive controller for an uncertain constrained linear system. The control signal is specified in terms of both feedback and feedforward components, where the feedback is designed to maintain the state within a prescribed ellipse in the presence of unknown bounded disturbances and system perturbations. The feedforward component ...Conference Paper -

May You Have a Strong (-Typed) Foundation, Why Strong-Typed Programming Languages Do Matter
(2004)2004 IEEE International Conference on Robotics and AutomationProgramming efficient and reliable code can be considered a non-trivial task, as it requires deep understanding of the problem to be solved along with good programming skills. However, software frameworks and programming paradigms can provide a dependable infrastructure upon which better programs can be written and deployed. This allows engineers to focus mainly on their task, while relying on the underlying run-time environment for taking ...Conference Paper -
Open Challenges in SLAM: An Optimal Solution Based on Shift and Rotation Invariants
(2004)2004 IEEE International Conference on Robotics and AutomationThis paper starts with a discussion of the open challenges in the SLAM problem. In our opinion they can be grouped in two main and distinct areas: convergence of the built map and computation requirement for real world application. To deal with the previous problems, a solution in the stochastic map framework based on the concept of the relative map is proposed. The idea consists in introducing a map state, which only contains quantities ...Conference Paper -
Bayesian Programming for Topological Global Localization with Fingerprints
(2004)2004 IEEE International Conference on Robotics and AutomationThis work presents a localization algorithm for indoor environments. The environmental model is topological and the approach describes how a multimodal perception increases the reliability for the topological localization problem for mobile robots, by using the Bayesian programming formalism. For the topological framework the fingerprint concept is used. This type of representation permits a reliable and distinctive environment modeling. ...Conference Paper
