摘要
为获取回转筒类设备多种颜色物料的安息角,研究了一种通过图像处理技术测定物料安息角的方法。分别对回转筒内物料进行图像信息获取、物料分离与背景去除、干扰信息的去除以及主成分分析,最后确定物料安息角的大小。
In order to measure the repose angle of particles with various colors in the equipment with rotating cylinder,the method of image processing is investigated to obtain the size of the angle of repose,including pictures information fetching,material separation and background removal,removal of the interference information.Finally,the material repose angle is obtained by principal component analysis.Experimental study is carried out to verify the effectiveness of the method.
