“…Visualization extends the frame of scientific research, providing an opportunity to present data in various forms for comprehensive and versatile analysis. The support of visualization by vision-based methods for 3D reconstruction and texturing is very important in case of visualization of real objects of complicated shape [1,2,3] or processes of complex nature and behaviour [4,5,6]. A particular demand for vision-based 3D reconstruction exists in aerodynamic and hydrodynamic researches, where visualization plays important role due to the nature of the studied processes.…”

Flow visualization is an important mean for studying flow processes in aerodynamics and hydrodynamics. It allows obtaining qualitative valuable information about flow behaviour, that is needed for understanding of aerodynamic performance of an aircraft, especially in critical conditions. With growing advances in 3D optical measuring techniques, accurate 3D registration and measurements of fast developing processes became possible. The paper addresses the problem of accurate metric 3D reconstruction of flow in hydrodynamic tunnel that is necessary for studying aerodynamic process in aircraft icing conditions. It presents the techniques developed for optical measurement system calibration and for accurate flow 3D registration, and the results of laboratory flow 3D reconstruction and visualization. Experimental evaluation of the developed techniques in laboratory hydrodynamic tunnel demonstrated high accuracy of 3D measurements and readiness for applying in aircraft icing study.

“…Visualization is playing an important role in scientific research, providing the best for analysis data representation. Visionbased methods for automatic generating accurate photorealistic 3D models of real objects of complicated shape [1,2,3,4] or processes of complex nature and behaviour [5,6,7,8] provide a new quality of data representation and, as a result, expand the possibilities of research efficiency. In aerodynamic and hydrodynamic flow visualization allows to exhibit the inner characteristics of the flow, that are essential for the process understanding.…”

Physical flow modelling is a powerful tool in aerodynamic researches, especially in analysis of complicated and dangerous conditions. It allows to study flow behaviour and to obtain reliable results via similitude concept, that is widely used in aerodynamics and hydrodynamics. Visualization of flow jets is one of the basic tools for analysis of flow behaviour under different flying conditions. Optical registration and 3D measurement techniques extend the capacities of visual flow study, providing both qualitative and quantitative data. The presented study addresses the problem of development of the vision-based technique for accurate flow 3D registration and 3D visualization. Algorithms allowing accurate 3D reconstructing of flow jets are presented, along with discussion of application for experimental flow 3D visualization.

This study proposes a rigid-body tracking based virtual avatar application method to increase the social presence and provide various experiences of virtual reality(VR) users in an immersive virtual environment. The proposed method estimates the motion of a virtual avatar through inverse kinematics based on real-time rigid-body tracking based on motion capture using markers. Through this, it aims to design a highly immersive virtual environment with simple object manipulation in the real world. Science experiment educational contents are produced to experiment and analyze applications related to immersive virtual environments through virtual avatars. In addition, audiovisual education, full-body tracking, and the proposed rigid-body tracking method were compared and analyzed through survey. In the proposed virtual environment, participants wore VR HMDs and conducted a survey to confirm immersion and educational effects from virtual avatars performing experimental educational actions from estimated motions. As a result, through the method of utilizing virtual avatars based on rigid-body tracking, it was possible to induce higher immersion and educational effects than traditional audiovisual education. In addition, it was confirmed that a sufficiently positive experience can be provided without much work for full-body tracking.
