3D Modelling

The team provides creation of three-dimensional models or design of 3D scanning systems for applications in industry, health industry, biology, agriculture, man-to-machine communication systems and other areas. Typical tasks include a 3D model of a human head or a human body to create a virtual 3D model (an avatar) that can be used in man-to-machine communication systems for audiovisual speech synthesis of a natural language or a sign language, in computer game industry or in other systems based on virtual 3D models of a human body. Another typical task is to create a 3D model of a component, product, plant, patient or body organ, using either 3D data available (e.g. in the health industry), or 3D surface scanning method. Yet another task is to design 3D scanning systems where more than one model is required and a system for repeated creation of 3D models must be developed.

Development of a 3D model typically includes:

• Identification and analysis of the scanned object
• Thorough analysis of conditions that can occur during scanning
• Design of a suitable process, 3D data capturing and pre-processing/analysis of these data
• The actual model development and its export into the required format

Design of a 3D scanning model typically includes:

• Identification and analysis of the scanned object
• Thorough analysis of conditions that can occur during scanning
• Selection of a suitable technology and proposal of a suitable process
• Hardware logistics, development of software to capture, edit or post-process 3D scans
• Commissioning

Experience confirms that 3D modelling is an efficient way to create models for different applications – from models of manufactured components used to control production on one hand to rapid prototyping on the other, to models of human heads for the “virtual counterpart” system, and medical 3D models of body organs or pathologies facilitating efficient image data analysis by physicians.

Motion Capture

The team provides motion capture analysis (MOCAP) – using the VICON optical system with passive reflective markers that can be placed on rigid objects, such as production line robots or quadrocopters, as well as human body using a special suit on which the markers can be applied easily. Motion capture data can be used to analyze movements in the health industry (physiotherapy, orthopaedics, etc.) or sports, as well as to provide realistic animations of body movements to design man-to-machine communication systems (sign-language synthesis), applications for computer game or filmmaking industries. The system also includes a unique CARA headset enabling efficient recording of accurate facial animation data. The pertinent software, that is a part of the system, is used to process different types of tasks (animations, medical applications, rigid objects, etc.).

Recording of 3D motion data analysis typically contains:

• Identification and analysis of the scanned object
• Thorough analysis of conditions that can occur during scanning
• Design of a suitable process, recording, pre-processing, analysis and post-processing of 3D motion data
• Delivery of data or processing results/analyses in the required format

Experience confirms that the use of motion-capture system data is an efficient way to create realistic movement for body and facial animations, obtain analyses of human body movements for medical applications and to provide basic information on the movement of tracked (e.g. robotic) models.
