摘　　要：提出了一种针对高粉尘强腐蚀环境的复合肥颗粒双目视觉检测系统。首先分析检测系统使用需求,提出实现连续大样本快速检测、实时显示结果、防腐除尘等功能的设计要求;提出3种双目视觉检测方案并进行对比,确定双目线阵CCD检测为可行方案。接着对系统硬件进行配置,并进行防腐除尘设计。为提高检测精度对电磁振动给料机进行自适应伺服控制,采用双相机并行的图像处理程序。对检测系统进行粒度分布实验,结果表明,检测系统误差在±3%范围内,满足实际应用要求。Aiming at the compound fertilizer particle inspection for strong corrosive and high dust environment,a kind of inspection system based on binocular vision was proposed.Firstly,using demand of the inspection system was analyzed,and the design requirements which can realize the continuous large sample testing,and result online showing and granulator closed-loop controlling were put forward.Then three binocular visual inspection plans were proposed and compared.Binocular linear CCD inspection was sure for the feasible plan.Hardware configuration,anti-corrosion and dust removal were designed.In order to improve the precision,electromagnetic vibration feeder was servo controlled,which was feedback by robot vision.Also,double cameras parallel image processing program was used.Finally,particle size distribution experiment was executed.The results show that the system error is within ±3%,facilitative for practical application.
