Design, analysis, testing and applications of two-body and three-body kinematic mounts
Johannes Richard Cornelis Geerit Kruis
Kinematic couplings are used when two rigid bodies need to be repeatedly and accurately positioned with respect to each other. They allow for sub-micron positioning repeatability by suppressing play and reducing strains in the bodies. Typical applications ...
EPFL2016Fixed-wing Micro Aerial Vehicle for Accurate Corridor Mapping
In this study we present a Micro Aerial Vehicle (MAV) equipped with precise position and attitude sensors that together with a pre-calibrated camera enables accurate corridor mapping. The design of the platform is based on widely available model components ...
2015Determination of the centre of mass kinematics in alpine skiing using differential global navigation satellite systems
In the sport of alpine skiing, knowledge about the centre of mass (CoM) kinematics (i.e. position, velocity and acceleration) is essential to better understand both performance and injury. This study proposes a global navigation satellite system (GNSS)-bas ...
Taylor & Francis2015Robot-centric elevation mapping with uncertainty estimates
This paper addresses the local terrain mapping process for an autonomous robot. Building upon an onboard range measurement sensor and an existing robot pose estimation, we formulate a novel elevation mapping method from a robot-centric perspective. This fo ...
2014Automated Assessment of Digital Terrain Models Derived From Airborne Laser Scanning
This paper presents the derivation of surface-related quality indicators describing the confidence-metrics of the final geo-products de- rived from airborne laser scanning (ALS). We first discuss the number of factors influencing the qual- ity of the digit ...
2012SEARCHING LOST PEOPLE WITH UAVS: THE SYSTEM AND RESULTS OF THE CLOSE-SEARCH PROJECT
This paper will introduce the goals, concept and results of the project named CLOSE-SEARCH, which stands for ’Accurate and safe EGNOS-SoL Navigation for UAV-based low-cost Search-And-Rescue (SAR) operations’. The main goal is to integrate a medium-size, he ...
2012Modelling wind-driven rain on buildings in urbanized area using 3-D GIS and LiDAR datasets
Luca Rossi, François Golay, Sylvain Coutu, Claudio Magalhaes Carneiro, Pauline Emery, Vera Wyrsch
This study investigated the distribution of the fraction of rainfall intercepted by the facades of buildings located in an urbanized area. We used the frequently used semi-empirical standard ISO-15927-3 to simulate Wind-Driven Rain on facades. The implemen ...
Elsevier2012Automated approach for rigorous light detection and ranging system calibration without preprocessing and strict terrain coverage requirements
Light detection and ranging (LiDAR) has demonstrated its capabilities as a prominent technique for the direct acquisition of high density and accurate topographic information. To achieve the potential accuracy of such systems, a rigorous system calibration ...
Spie-Soc Photo-Optical Instrumentation Engineers2012Technical note: Preliminary estimation of rockfall runout zones
Rockfall propagation areas can be determined using a simple geometric rule known as shadow angle or energy line method based on a simple Coulomb frictional model implemented in the CONEFALL computer program. Runout zones are estimated from a digital terrai ...
2011In-flight quality assessment and data processing for airborne laser scanning
One of the main problems of today's Airborne Laser Scanning (ALS) systems is the lack of reliable data QA/QC (Quality Assurance/ Quality Control) within or shortly after the airborne survey campaign. This thesis presents the development of methods to perfo ...
