Generic information

Description

The central topic of our laboratory is computational optical sensing and imaging. The main research challenge is to derive precise abstract information or decision from large complex noisy topological data sets captured by one or multiple optical sensors. We apply special optical arrangements like different holographic setups and fluorescent illuminations for microscopic imaging or large view angle multi-camera systems in monitoring. The heavy load computational process is handled by many-core processor arrays, like GPU in desktop applications or low-power FPGA in embedded systems.

Main Research Areas

  • Design and application of the Color or Monochrome Digital Holographic Microscopes
  • Automatic monitoring, classification, counting of microbiological organisms
  • Visual remote aircraft detector sensor for UAVs
  • Visual navigation for UAVs
  • Implementation of high-speed many-core processor architectures in FPGA
  • High performance FPGA based embedded vision system development
  • Design and programming of mixed signal focal-plane sensor-processor systems

The laboratory has three major topics. The first is the digital holographic microscopy. Here an already established technology for automatic algae, protozoa, and worm detection is licensed to our industrial partner (Knot Kft.), while further research activities are pursued to combine the holographic microscope with other technologies. The second topic is the UAV collision avoidance system development. In this project, an embedded multi-camera vision system is being built for identifying and tracking remote aircrafts and deriving inertial data from optical flow for navigation. This work is done in-cooperation with another laboratory of our institute, which develops the aircrafts, and their navigation and control systems. The third topic is many-core processor architecture implementation in FPGAs, for example vision processors or aerodynamic modeling.

Main Achievements

In cooperation with the Waterworks of Budapest we have developed an automatic water quality monitoring system DHM. This device, by using the digital holographic microscope technology, is capable to detect, classify and count algae in water samples real time.
Water quality monitoring device is developed for waterworks cooperation with Knot Ltd., where we can real-time detect and count the number of worms. Proliferation of the worms, otherwise, is a byproduct of the applied filtering process.
On board visual collision forecast and avoidance system has been developed for motor vehicles and for UAVs. (LOCUST project, VOLVO, IMSE and SZTAKI-SCL, PPKE, ONR).
Extremely high sensitivity silicon based THz sensor array has been developed and it can be applied for special imaging solutions.
High speed computing is implemented on FPGA architectures Kiloproc. This makes it possible to simulate partial differential equations close to real time rates.

Products/Services

The laboratory with its industrial partners delivers industrial microbiological measurement devices for automatic identification and counting algae, protozoa, and worm species either in surface water or in already processed drinking or industrial water. Our industrial customers are waterworks, sewage farms, food and beverage industry, and environmental protection agencies.

Other services:

  • High speed computing by FPGA
  • IBM CELL Blade cluster can be used for research purposes after registration (contact).
