In order to investigate the mixing effect of pesticide and water in sprayer, the mixing image in the mixer was acquired by a high speed camera through adding tracing particles in pesticide. And a new method using morphology to improve the nonuniformity was developed for the original mixing image. Then the mixing image was segmented by the method of gray-enhancing Otsu effectively. The parameters such as the coordinate of the particle's centroid were also calculated.
