| Abstract: | 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. |
