OGX|OPTOGRAPHX performs and implements scientific research projects combining many - frequently different - science disciplines. The group specializes mainly in the following fields: optics, optoelectronics, image processing, programming, 3D graphics and visualization. The range of works currently carried out includes: optical shape measurement, computer vision (object tracking and analysis), multimedia (3D graphics and virtual reality) and biomechanics (gait measurement methods and analysis).
The majority of projects and research and development works are run in close cooperation with Polish and foreign scientific centers and companies from a wide field of new technologies. Till now our group has been cooperating with the following organizations, among others: Akademia Ekonomiczna w Poznaniu (Poland), DIERS International GmbH (Germany), Eberhard Karls Universität Tübingen (Germany), Katholieke Universiteit Leuven (Belgium), Rimkevicius and Gintautas Company (Lithuania), SMARTTECH Sp. z o.o. (Poland), Telewizja Polska S.A. (Poland) and VELOMAT Messelektronik GmbH (Germany).
We are interested in starting a scientific cooperation (research and development) with other centers and companies. If your organization is willing to display interest in a scientific or commercial project, please do not hesitate to contact us.
3DMADMAC (3D Measurement with Algorithms of Directional Merging And Conversion) is a complex 3D objects scanning system. The developed solution includes both hardware and software for control and data processing. A universal, modular system structure allows to setup its custom configuration. Owing to this it is possible to configure different measurement volumes, inaccuracies and measurement times adequate to a selected object.
applications: metrology, multimedia, medicine
System OGX|4D makes possible noncontact measurements of 3D dynamic objects whose surfaces can change during measurement sequence (shape and position). Measurement is based on the active fringe projection method with a color coded fringe marker and on the CNDZF method. The system needs only one frame to be captured by a camera to obtain information about object surface. This solution offers a much shorter measurement time in comparison with measurements using other standard techniques based on structural light methods.
applications: computer graphics and animations, virtual reality systems, medical systems (orthopedics and rehabilitation), engineering systems (dynamic analysis), services for artist.
The main goal of Aurora project is to research and develop a system for human skeletal movement reconstruction basing on measured shape of human lower limbs. At present, physicians and therapists have to perform very complicated examinations (very often harmful e.g. X-Rays) and analysis of human stature and gait in order to precisely identify any disease and/or pathological changes. Currently there are no tools or methods, which could considerably help automate this analysis. There are also no methods for performing 4D (3D plus time) measurements of a human body.
The project is carried out in cooperation with DIERS International GmbH, Eberhard Karls Universität Tübingen, Katholieke Universiteit Leuven, Rimkevicius and Gintautas Company, SMARTTECH Sp. z o.o. and VELOMAT Messelektronik GmbH.
applications: medicine, multimedia
The goal of Versatile project is to develop a system for virtual representation and full lifecycle tracking of industrial/technical parts, simultaneously maintaining a firm relation between these representations and particular objects.
The project involves research and development of a network system for fast tracking, identification and localization of single elements and its groups. Defined goals require the use of RFID and bar code identification systems, 2D-3D computer vision, metrological measurements methods, temporal databases, mobile computers, wireless communication, fast computer networks, data analysis based on a network system and graphical user interfaces.
applications: metrology, quality management, industry
OGX group created a three dimensional digitalization and an interactive presentation for the Anna and Ignacy Iwaszkiewicz Museum in Stawisko, Poland. Three dimensional digitalization is a modern method of a filling system for art/museum collections. It allows to create full three dimensional models with a very high complexity and details with preserving information about shapes and also colors. Obtained models can be used for several purposes like documentation, education and other museum activities.applications: interactive resentations, museums, virtual exhibitions
Virtual Studio allows to transfer a TV presenter/actor and other elements of a real stage design into a virtual environment. The system is based on synchronization of orientation and coordinates of a real camera which records a real scene with a computer generated background. Owing to this, after combining a picture of real objects recorded in a bluebox with a picture of virtual background, a viewer has an impression of watching one coherent scene.
Virtual Studio is a part of a larger project performed at the Warsaw University of Technology within the framework of the State Committee for Scientific Research coordinated by Polish Television titled "System of Audiovisual Signal Sharing in the Polish Optical Internet in a Manner Ensuring Implementation of Interactive Television".
The project is carried out in cooperation with Katedra Technologii Informacyjnych Akademii Ekonomicznej in Poznań and Telewizja Polska S.A.
applications: objects cracking, multimedia, television
