摘　　要：基于计算机视觉和自动控制技术,设计了排种器试验台检测系统。该系统适用于各种排种器的精播、穴播及条播性能的试验和检定,并可生成丰富翔实的试验数据报表。为此,论述了检测系统的设计与构成,对排种图像采集处理的总体流程、图像的拼接、阈值分割和种子边缘提取等内容一一做了叙述,并讨论了数据的综合处理、各种统计和评价的依据等。同时,为了检验该系统的可靠性和准确性,在JPS-12排种器试验台上进行了多种速度下的玉米精播性能检测试验。The detection system of seed mertering test-bed,based on computer vision and automatic control technology,applicable to performance experiment and verification of all kinds of precision seeding,bunch planting and drilling,can generate full and accurate test data report.This paper discusses the design and composition of detection system,the seeding image acquisition and processing of the overall process,image stitching,segmentation and edge detection,etc were described,and discussed the data in an integrated manner,various statistics and the basis for such review,at the same time to test the reliability and the accuracy,in the JPS-12 metering test table we had a multi-speed performance testing of corn seeding trial.
