【摘要】 本文通过分析传统测量种猪体重的方法所遇见的问题,探讨了一种无接触式测量方法,即通过计算机视觉技术,测量和计算种猪的投影面积以及体尺参数,观察它们与体重之间的线性关系。并利用真实体重数据得出体重和体积的回归公式,用新样本验证此回归公式,平均相对误差为3.2%。实验证实了利用计算机视觉方法来估测种猪的体尺和体重,可以减少人力物力,避免由于猪的应激反应而给生产带来的损失,在种猪的科学饲养管理中具有实用意义。更多还原

【Abstract】 Measurement of pig weight is very important in pig production. By analyzing the problems in traditional methods of estimating the weight of pig, a new method was developed to determining the weight of pig which applies computer vision techniques to pig production. The pig’s weight is estimated by the projected areas and dimensions. By comparing with the real weight, the mean relative error is 3.2%. The experiment indicates that this hands-off method has great significance in scientific management of the pig’ s production which does not require large labor and material resources, and also avoid the loss in production resulted from stress.更多还原
