摘　　要：开发了一套基于动态称量和图像处理的鸡蛋在线检测系统。通过应变片式传感器动态检测质量，用图像处理检测鸡蛋长短轴。对117个鸡蛋进行在线验证，建立了鸡蛋长短轴检测模型，实现了鸡蛋质量和长短轴的在线检测，并对通过不同方法所得到的鸡蛋长短轴及鸡蛋质量进行了对比。结果表明，在线系统检测鸡蛋质量误差小于±1g，短轴误差范围-0．5～0．7mm，长轴误差范围±0．6mm，鸡蛋检测速率为4枚／s，满足在线检测的要求，证明在线系统具有较强的合理性及鲁棒性。An online detection system based on dynamic weight measurement and graphic processing skill was developed. The developed system weighted dynamically the mass of egg sample using strain gauge weight and calculated major-minor-axis of egg through image generation. Comparison of the egg long axis and egg mass by different methods proved that the online system had a strong robust. Sample of 117 eggs were used to check the system, with mass error of ± 1 g, minor-axis error of - 0.5 - 0.7 mm and major- axis error of ＋ 0.6 mm. The correct classification rate of XL grade, L grade, M grade and S grade were 100% , 100% ,93.84% and 100%. The detection velocity was 4 eggs per second. Experiments show that the online detection system meets corresponding standards.
