Summarized the measurement methods commonly used in the experimental research on the characteristics of suspended sediment movement, introduced the basic principle of image processing technology and the system composition. In view of several specific problems in image processing, especially the thickness of light sheet and particle concentration The choice, combined with practical experience were discussed. Using the developed particle tracing and image processing system, the kinetic characteristics of suspended particles in the flume were measured. Practice shows that image processing technology provides a powerful tool for the study of the movement characteristics of suspended particles.
