Computer program fluid flow measurement system, fluid flow measurement method, and image processing method

摘要

The filtering process can be a background data by removing noise by using the image data of the two sheets, and greatly reduces the number of shot images required for removing the fiber noise, to achieve a time saving and computational burden. That is, the difference between the second image data from the first image data, the luminance values ​​in a second image data and the first image data, first the background processing means, the coordinates when the difference is less than a predetermined value by treating the background, to obtain a first background process data with the background processing first image data. Then, the difference between the first image data from the second image data, the luminance values ​​in a second image data and the first image data, the second background processing means, said if the difference is less than a predetermined value Get the second background data processing with the background processing the second image data by treating the background coordinates. The particle distribution data processing means for image processing of the luminance distribution pattern of the particle image using a second background processing data in the first data processing background.
