Using high-speed video technology, the establishment of a precision metering device performance analysis system was developed. By the detailed analysis to dynamic images,the posture and trajectory of the seed are extracted, and some factors of a metering device leakage sowing are identified. To establish a rational test and the optimal combination, the precision meets demand of use. Experiments show that use of the systems studied in this paper precision metering device performance study is feasible and practical.
