| Abstract: | In this research, fuzzy gray degrees were established to quantitatively evaluate the influential factors in the image characteristics of turbulence motion locus. Through selecting different influential factors during image acquirement and establishing factor-parameters array, the mathematical model of fuzzy gray evaluating system can therefore be structured. After calculating those fuzzy gray relational degrees between those factor-parameters and image characteristics, the external influence on image characteristics can be quantized systematically. By repeated experiments their influence disciplines are determined, this paper also provides technical references and new research ideas for future turbulence monitoring in practice as well. |
