Reconstruction of airborne laser scanner trajectory from data
Multi-echo airborne laser scanner (ALS) has shown increasing utility for forestry applications in the two past decades. Among the numerous algorithms developed to process ALS data on forest environments some require to know actual sensor trajectory and deduced angles of incidence. However, sensor trajectory is not part of the ALS standard LAS file ...
Learning fluid trajectory models for time-resolved PIV
We present a new multiframe cross-correlation (Lucas-Kanade based) algorithm for time-resolved PIV. This algorithm leverages time coherence in image sequences by decomposing the temporal dependency of motion on an arbitrarily chosen trajectory basis. We propose to learn this basis from the data by performing a Principal Component Analysis on trajec...

Lever Arm Compensation for a Motorcycle Trajectory Reconstruction System
An approach has been proposed in a previous work, to reconstruct motorcycle trajectories, based on INS / Odometer data fusion. A wheel model was proposed to improve the estimation of the traveled distance from the odometer and CAHRS algorithm was used to better estimate the orientation of the motorcycle from inertial and magnetic data. In this pape...
L'alimentation comme levier de développement territorial ? Réflexions tirées de l'analyse processuelle de deux démarches...
L'article porte sur les mécanismes à l'oeuvre dans la territorialisation de l'alimentation dans des contextes ruraux français. L'approche empirique repose sur deux cas de démarche de développement territorial en Auvergne-Rhône-Alpes. Le cadre d'analyse croise approches temporelle et territoriale, la démarche repose sur la réalisation d'entretiens s...
Unravelling System Optimum Structure by trajectory data analysis
This work investigates network-related trajectory features to unravel trips that the most contribute to the system under-performance. When such trips are identified, features analysis also permits to identify the best alternatives in terms of routes to make the system to its optimum. First, data mining is carried out on trajectories obtained from r...
