Research Projects

Biolab II - Evaluation of biometric verification systems

The project continues the research work and test operation of the Biolab project. In addition to existing research focuses, the project is also dedicated to new approaches in biometrics, such as the development of quality metrics for synthetic characters and the use of time-of-flight cameras to detect overpass attacks.

ROSE3D - Robust and Safe 3D Camera System

The aim of the project is to develop a new system approach for optical 3D imaging cameras that combines different measurement approaches in an extended measurement architecture and thus overcomes the current limitations of today's 3D cameras. The technology to be developed should enable robust and safe operation, especially in functional safety applications. To this end, the measuring range and robustness in the detection of fast movements are to be improved compared to the state of the art. The planned basic technology is the ToF camera method (time-of-flight method). FKZ: 13FH554KX1

NAkSU - New analysis methods for complex safety and environmental data

Modern sensor technology and mobile measuring systems enable close monitoring of environmental data and pollution. Examples are climate data and trends, pollution and emissions, or changes in the microclimate due to large-scale construction measures. Through municipalities ("Smart Cities"), but also in citizen science ("Citizen Science" and "Citizen Sensors") projects, a wide variety of sensor systems are used, which can also provide important information in the event of disasters and major damage.

Biolab - Evaluation of biometric verification systems

The Biolab project is dedicated to the continuous and comprehensive evaluation of biometric systems. The project investigates the performance, security and usability aspects of biometric systems. The results lead to training courses and workshops for authorities, police forces, manufacturers and end users. The Biometrics Evaluation Center (BEZ) at the Sankt Augustin campus is the place of implementation.

IR and ToF measurement and algorithms for automatic signal evaluation for a mobile vehicle classification system (RaIT vehicle classification)

Cities and municipalities must create the right framework conditions for road traffic so that it is compatible for everyone from an ecological, economic and social point of view. To ensure this, precise measurements of traffic volumes and a classification of road users are required.
