技術說明

一種流體分析方法。取得校正流體於空間中的第一純量梯度分佈資訊。擷取並處理校正流體的校正紋影影像，以獲得校正紋影影像的亮度分佈資訊。將校正流體的第一純量梯度分佈資訊與校正紋影影像的亮度分佈資訊相對應，以獲得第一純量梯度資訊與亮度分佈資訊的對應關係。擷取並處理待測流體的紋影影像，以獲得紋影影像的亮度分佈資訊。根據第一純量梯度資訊與亮度分佈資訊的對應關係將紋影影像的亮度分佈資訊轉換為待測流體的第一純量梯度分佈資訊。此外，一種流體分析系統亦被提出。 An analysis method for fluid is provided. The spatial distribution of the first scalar gradient of a calibration fluid is obtained. A calibration schlieren image of the calibration fluid is captured and processed to obtain intensity distribution of the calibration schlieren image. The distribution of the first scalar gradient of the calibration fluid is corresponded to the intensity distribution of the calibration schlieren image so as to obtain the relation between the first scalar gradient and the intensity. A schlieren image of a test fluid is captured and processed to obtain intensity distribution on this schlieren image. The intensity distribution of the test schlieren image is converted into first scalar gradient distribution of the test fluid according to the relation between the first scalar gradient and the intensity. Besides, an analysis system for fluid is also provided.
