Self-calibration of visual sensor networks

Many multi-camera applications rely on the knowledge of the spatial relationship among the individual nodes. However, establishing such a network-wide calibration is typically a time-consuming task and requires user interaction. In her recent work, Jennifer Simonjan developed a decentralized and resource-aware algorithm for estimating the poses of all camera nodes […]

UAV motion planning for multi-coverage

Unmanned aerial vehicles (UAVs) with onboard cameras are increasingly deployed in various applications including surveying, search and rescue, inspection as well as video production. In all these applications, the UAVs move – in many cases autonomously – to capture imagery of sufficient quality of the environment or objects of interest.  […]

Aerospace best paper award

Stochastic Trajectory Generation Using Particle Swarm Optimization for Quadrotor Unmanned Aerial Vehicles (UAVs) has been selected as the best research article published in 2017 in the MDPI Aerospace journal. The paper is co-authored by Babak Salamat and Andrea Tonello. It provides a realistic stochastic trajectory generation method for unmanned aerial vehicles. […]

UWB connectivity in industrial environments

The introduction of wireless connectivity in industrial environments promises a rapid and cost-effective reconfiguration of machines and sensors. A key question in this context is: Which wireless technology is best suited for industrial settings? Many of the prevalent technologies, like WiFi and ZigBee, do not meet the requirements of certain […]

The Spiderino Swarm Robot

Playing with toys pays off! We have designed a low-cost research robot based on the Hexbug Spider toy in order to combine the interesting locomotion of the toy with some embedded intelligence. Our modification replaces the robot head with a 3D-printed adapter, consisting of two parts to provide space for […]

A bachelor thesis evolved into a startup company

In 2014 Michael Gruber started his bachelor thesis at the Pervasive Computing group by investigating different software tools for simulating distributed algorithms in multi-camera networks. Together with his supervisor Melanie Schranz – at that time teaching and research staff member at NES – he explored the Unity game engine as […]

A Game of Clones

In October 2017 we took the first steps in the research project “Game of Clones – Students model the dispersal and fighting of the knotweed”, a project funded by the research program Sparkling Science of the Federal Ministry of Science, Research and Economy. The Game of Clones project should approach […]

Intelligent boarding to ski lifts

A novel boarding solution for cabin-based transport systems — e.g., ski lifts, cable cars, subways — is being discussed in industry and has already been implemented in the Austrian skiing resort Bad Gastein: In order to avoid long queues at succeeding boarding stations, a display in the boarding area tells […]

Efficient time synchronization of sensor networks by means of time series analysis

Wireless sensor networks have many applications, ranging from industrial process automation to environmental monitoring. Researchers at the Alpen-Adria-Universität Klagenfurt have recently developed a time synchronization technique and have carried out experimental performance testing. The method developed learns the behavior of the sensor clocks, making it particularly efficient in terms of […]
