摘　　要：为了避免因人工测量生猪体重给生猪带来较严重的应激反应,影响生猪身体健康,严重时导致生猪死亡。综述了计算机视觉技术在生猪体重智能估测方面的研究进展,通过相机获取生猪2D或3D图像数据,提取生猪体长、体高、腹围宽、胸围宽和背部面积,基于线性函数、偏最小二乘法函数、RBF、MLP等非线性函数,对生猪体重自动预测模型进行研究,实现非接触式生猪体重估测,能及时、快速且无伤害地获取生猪体重信息。对比分析各项相关研究报道可知:线性预测模型的准确率明显低于非线性预测模型,且基于非线性函数构建的体重估测模型的平均误差小于5%,与实际体重的平均相关性约0.97,说明生猪非接触式体重估测方法的可行性,为生猪的精准饲养管理提供了一种有效的监测手段,减少人力资源损耗,提高生猪养殖福利。In order to avoid serious stress response to pigs due to manual measurement of pig body weight,which will affect the health of pigs,and even lead to death of pigs in severe cases.The research progress of computer vision technology in intelligent estimation of pig body weight is reviewed.The 2D or 3D image data of pigs are obtained through cameras,and the body length,body height,abdominal width,chest circumference and back area of pigs are extracted.Based on linear functions,partial least squares Multiplication function,RBF,MLP and other nonlinear functions are used to study the automatic prediction model of pig body weight,realize non-contact pig weight estimation,and obtain pig body weight information in a timely,fast and harmless manner.Comparative analysis of various related research reports shows that the accuracy of the linear prediction model is significantly lower than that of the nonlinear prediction model,and the average error of the weight estimation model constructed based on the nonlinear function is less than 5%,and the average correlation with the actual weight is about 0.97.The feasibility of the non-contact weight estimation method for live pigs is illustrated,and it provides an effective monitoring method for the precise feeding and management of live pigs,reduces the loss of human resources,and improves the welfare of live pigs.
