This paper describes a new approach on the measurement of droplets volume in microfluidic system based on image processing. This approach successfully detects the diameter of a single droplet. Image processing via MATLAB is used to capture droplets volume in the microfluidic system. Compared with other methods, this approach has enormous advantages of real-time, simpleness and wide applications. Because of the demand of constant accurate flow in microfluidic system, the approach to measure volume of microfluid is in urgent need. The accuracy of the volume measurements is limited by the selected parameters of the image processing. During the experiment, the optimum parameters of the image processing are selected through repeated tests. The obtained results are in good agreement with the demand. The results show that microfluid can be controlled in quantitative. That makes an important application field of micro fluidic is in pharmacy, microchemistry, biochemistry and bioanalysis.
