In-flight Accuracy Estimation for Airborne Lidar Data

Yannick Stebler

One of the main problems of today’s Airborne Laser Scanning (ALS) systems is the lack of reliable data quality assessment within or shortly after the airborne survey campaign. This paper presents the development and implementation of a tool that allows com ...

Vision-based control of near-obstacle flight

Antoine Beyeler

Lightweight micro unmanned aerial vehicles (micro-UAVs) capable of autonomous flight in natural and urban environments have a large potential for civil and commercial applications, including environmental monitoring, forest fire monitoring, homeland securi ...

Cooperative Localization for Autonomous Underwater Vehicles

Alexander Bahr

Self-localization of an underwater vehicle is particularly challenging due to the absence of Global Positioning System (GPS) reception or features at known positions that could otherwise have been used for position computation. Thus Autonomous Underwater V ...

Automated Processing of GPS/MEMS-IMU Data for Position, Velocity and Attitude Determination

This master thesis deals with the problematic of the integration of Global Positioning System (GPS) measurements with inertial data acquired by a Micro-Electro-Mechanical System (MEMS) Inertial Measurement Units (IMU). This technology is employed for the p ...

Vision-based control of near-obstacle flight

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

This paper presents a novel control strategy, which we call optiPilot, for autonomous flight in the vicinity of obstacles. Most existing autopilots rely on a complete 6-degree-of-freedom state estimation using a GPS and an Inertial Measurement Unit (IMU) a ...

Optimization of two GPS/MEMS-IMU integration strategies with application to sports

Jan Skaloud, Adrian Wägli

The application of low-cost L1 GPS receivers integrated with micro-electro-mechanical system (MEMS) inertial measurement units (IMU) allows the continuous observation of position, velocity and orientation which opens new possibilities for comparison orf at ...
