| Abstract: | In this paper, the machine vision method was adopted to detect the performance of precision seedmeter. A dynamic seeding flow was shot by a CCD camera and a series of treatments were proposed including the deleting of backdrop, binary treatment, smooth image, the picking up of exigent values, image standardization, and so on. The frequency statistic method of the number of cell seeds was set up based on the serial time. Finally, the performance of the seedmeter was counted. The experiment showed that the method precision and velocity are satisfying. |
