【Abstract】 The paper used visual means to study the speed and capacity of signal transmission, the dynamic properties and clarity of image. The topic related to optical system design, image acquisition and image processing technology. The study and main results are as follows:(1) The paper studies the structure of the optical illumination system, choose a new method to obtain laser-light source, eliminate the pre-acquisition target vague problems, and enhance the clarity of the image.(2) The paper uses CCD camera to get the flow of images in multiphase flow pipeline. It is an effective solution to cope with the poor dynamic performance and continuity of screen. It is suitable for online real-time detection of multiphase flow state.(3) The paper apply moving object tracking method in fluid image processing. Use three image features as a measure of image subtraction. The experiment proved their contribution.(4) Using image processing technology to get the edge of the image characteristics, According to image features, It detects the various parameters of multiphase flow.更多还原
