    种猪体重三维预估模型的研究

    Research on three-dimensional model of pig′s weight estimating

    • 摘要: 在利用图像处理技术实时预估活体猪体重中,选用的预估模型对能否获得较好精准性至关重要,同时也影响图像处理算法实现的复杂性、稳定性及高效性。该文在充分考虑猪的体形特点及其与猪体重影响因素的基础上,将猪体的头部和躯干分别近似为圆锥体和圆柱体,以此建立种猪体重的三维预估模型。经与实测数据比对,表明该预估模型具有较好的准确性,为实现猪体重的无损测量提供了一种新的方法。

       

      Abstract: Aiming at estimating weight of pig with image processing technology, felicitous estimating model is the base and key to achieve good results also connected directly to the complexity,stability and high efficiency of processing Algorithms. Analysised the factors correlated to weight estimating and characteristics of bodily form of pig,divided the pig into head and body and supposed them as a cone and a columniation. Set up an estimate model based on three-dimension. The results of comparisonand analysising betweenactual and estimating weight values verified the estimating model through experiment and got a pretty precision in the range of experiment weight datas.This study provided a new method to estimate pigs′ weight non-destructively.
