基于激光三维成像自动判定奶牛体况技术研究

摘要

当前奶牛体况判断多是人工进行,较为落后,耗费大量的人力以及时间,导致判断误差较大,结果不可靠.为此,提出基于激光三维成像自动判定奶牛体况技术.首先对摄像机进行标定,再利用标定后的摄像机激光三维扫描奶牛体况,得到奶牛三维非刚性坐标.奶牛大部分体况可转换成两点之间的距离或三点之间夹角的测量;在此基础上,对奶牛体型性状指标进行判断,以达到自动判定奶牛体况的目的.实验结果表明,采用所提方法对奶牛体型性状指标进行判断,操作简单易行,判断误差较低,结果较为可靠.%The cow body condition judgment is artificial, is relatively backward, spend a lot of manpower and time, error in judgment, the result is can not reliable.Therefore, based on laser automatically decides the cow body of three-dimensional imaging technology.For camera calibration in the first place, then the calibrated camera laser 3D scanning the cow body condition, get the cow three-dimensional nonrigid coordinates.Cows most fission conditions can be converted into a distance between two points or the angle between the three measurements, on this basis, the cow shape character index to judge, in order to automatically determine the cow body condition.The experimental results show that the proposed method to judge of the cow body shape indicators, the operation is simple, easy to determine error is lower, the result is more reliable.
