基于三维点云的奶牛乳房外形特征分析方法

Cow Breast Shape Features Analysis Method Based on Three-Dimensional Point Cloud

针对奶牛乳房外形特征分析,提出一种利用计算机技术的奶牛乳房外形分析方法.首先,通过机器视觉技术获得奶牛乳房的三维点云,并利用封闭算法将非封闭的三维点云封闭化后,计算奶牛乳房的体积;随后,将封闭的三维点云与一组平行平面相交,从而获得一组二维曲线集合;最终,通过分析二维曲线的特征,使奶牛乳房的外形特征分析与对比成为可能.本方法为进一步深入研究高产奶牛与低产奶牛在乳房外形特征方面的差异奠定了基础.

Aimed to analyse of cow breast shape characteristics, an analysis method of cow breast shape by means of computer technique was developed. First, after three-dimensional point cloud of cow breast was obtained through the method of machine vision technology, and using the closed-algorithm to change the non-closed three-dimensional point cloud into closed cloud, the volume of cow breast can be calculated. Second, the closed three-dimensional point cloud will intersect with a set of parallel planes, so that a set of two-dimensional curves can be obtained. Finally, by analyzing the characteristics of the two-dimensional curves, the analysis and comparison of the cow breast shape characteristics are made possible. This method can benefit further studies about the differences in breast shape characteristics of the high-yielding and the lowyielding dairy cows.
