【Abstract】 A precision seedmeter performance detecting system was established by means of computer image processing technology in this paper. The processes of seed dynamic image were analyzed in detail. By means of the techniques of reinforcement, smoothing, sharpening and separating, image quality was enhanced effectively. According to the area of the seeds and the distances between them the characteristic extracting methods of precision seedmeter performance detecting were put forward. Based on computer vision, an application software of auto detecting performance was programmed.The detecting tests showed that accuracy of detecting system was adapted to the demand for performance detecting. The research method in this paper may also be applied to dynamic image processing and mode identifying of the other agricultural products.更多还原
