Many user localization technologies and methods have been proposed for either indoor or outdoor environments. However, each technology has its own drawbacks. Recently, many researches and designs have been proposed to build a combination of multiple localization technologies system which can provide higher precision results and solve the limitation in each(More)
This paper presents the analysis and discussion of the off-site localization competition track, which took place during the Seventh International Conference on Indoor Positioning and Indoor Navigation (IPIN 2016). Five international teams proposed different strategies for smartphone-based indoor positioning using the same reference data. The competitors(More)
User localization is the key to enable many location-based services. Localization techniques have been actively studied recently due to service as well as safety and security matters. There are many localization systems with different architectures, configurations, accuracies and reliabilities. However, no technique is now generally applicable for indoor(More)
This study investigates bicycle dynamic properties by using system identification approaches. The nonlinear bicycle model with configuration parameters from a previously developed benchmark model is studied. The roll angle of the bicycle is controlled at different speeds to generate input-output data including steering torque, roll and steering angles. The(More)
This paper introduces our work in the framework of Track 3 of the IPIN 2016 Indoor Localization Competition, which addresses the smartphone-based tracking problem in an offline manner. Our approach splits the path-reconstruction into several smaller tasks, including building identification, floor identification, user direction and speed inference. For each(More)
This paper describes an ESP (electronic stability program) controller system which acts on the brake system to generate a corrective yaw moment that helps the vehicle to follow the course desired by the driver. The corrective yaw moment, referred to as compensated yaw moment, is based on the estimation of the desired yaw rate as well as the sideslip angle.(More)
In this paper, a complete indoor navigation assistance system for visually impaired people is introduced. Different multimedia technologies are integrated in a single system in order to provide a precise, safe and friendly navigation service. First, the environment is modeled and represented. After that, the user location is determined by combining Wi-Fi(More)
Person tracking is crucial in any automatic person surveillance systems. In this problem, person localization and re-identification (Re-ID) are both simultaneously processed to show separated trajectories for each individual. In this paper, we propose to use mixture of WiFi and camera systems for person tracking in indoor surveillance regions covered by(More)
Behavioural scientists track animal behaviour patterns through the construction of ethograms which detail the activities of cattle over time. To achieve this, scientists currently view video footage from multiple cameras located in and around a pen, which houses the animals, to extract their location and determine their activity. This is a time consuming,(More)
