Аннотация
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.
Ключевые слова: aerodynamic flow visualization, optical 3D measurements, refraction, calibration, accuracy.
