AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Jusqu'à présent, les seules informations disponibles pour l'analyse des courses de ski se limitent aux temps intermédiaires et aux images vidéo. Bien que très spectaculaire pour le téléspectateur, une analyse vidéo (telle qua la technologie SimulCam de Dar ...
This paper presents a self-contained, light and flexible mapping system that can be quickly deployed into inaccessible areas. Although designed to measure wind-transported snow volumes and the snow avalanche runoff over and experimental site, the system is ...
Aerial photogrammetric mapping is a well-established industry. Its methods have been evolving progressively but not explosively over many decades. Entrenched, reliable procedures have been developed to overcome pitfalls along the processing chain, allowing ...
Downhill skiers enter a different dimension on the racecourse, but they are still subject to the laws of physics. A new Swiss system integrates GPS, video, and biosensors for precise position, velocity and heart-rate measurement, helping coaches and athlet ...
The Swiss curvilinear coordinate system for road data is currently under review. The geodetic laboratory at EPFL has designed a mobile system for the automatic determination of the road geometry: the Photobus. ...
Stringent requirements on the accuracy of attitude determi- nation are currently a major challenge for strapdown INS/GPS integration, which is at the core of self-contained airborne remote sensing and mapping systems. This paper reviews the error models fo ...
Systematic and random errors inherently present in all inertial sensors contribute to the long-term divergence of the navigation solution of an Inertial Navigation System (INS). To keep such long-term divergence under control while taking advantage of thei ...
The development or road telematics requires the management of continuously growing road databases. Mobile mapping systems can acquire this information, while offering an unbeatable productivity with the combination of navigation and videogrammetry tools. ...
Au cours de la dernière décennie, les systèmes de cartographie mobile utilisant GPS et INS pour la détermination directe des paramètres d'orientation (géoréférencement direct) sont devenus une alternative pertinente aux techniques s'appuyant sur le géoréfé ...
