Abstract: In connection with the malpractice of the property of the seed distribution by using the photoelectrical checking and the human measuring, this paper proposed the application of kinetic image processing to measurement of seeds distribution. The computer image processing system for measuring multi target high speed mass objects(seeds) was established, and the effect of optical source on kinetic objects and the acquisition process of image were also analyzed in detail. The suitable window of image processing was determined. The object and background were exactly found out by optimum entropy threshold. According to the edges and area of the seeds and the distances between the seeds, the general algorithm of detecting seeds filling property was successfully presented. The experiment proves that the error is small and the speed is high by using this system. It makes a foundation for checking the property of the seeds distribution. The experiment showed that the measurement precision and velocity are satisfying.
