Abstract: Investigations have been carried out in order to study the feasibility of applying image processing systems as new measurement technique and data acquisition devices in a hydraulic laboratory. An explanation of image processing technique, detailed information on necessary system components and a description of the used minimum configuration is given。Required performance characteristics, available capabilities and features of sophisticated image processing systems are outlined. Further processing of qualitative information - gained from well established flow-visualization techniques - is achieved by quantitive means with the new technique providing a reasonable accuracy. By picturing flow particles on their way through a flow domain Lagrange quantities have been measured and analyzed for two examples with predominating two-dimensional flow characteristics. Measurements are performed simultaneously at multiple points in real-time without the disadvantage of influencing the flow field by probes, Thus image processing, applicable for investigations where conventional flow measurement methods fail, can add significant newca ability to existing measurement instrumentation in a hydraulic laboratory.
