摘　　要：为实现瓷砖颜色分级的自动检测,提出一种基于CIE YU‘V'空间的色差计算方法。该方法将数据从RGB颜色空间转换CIE YU‘V'均匀颜色空间,利用U'、V'分量计算标准瓷砖与被测瓷砖的色差。通过对总体平均色差和小区域窗口色差进行分析,确定瓷砖颜色等级。该方法对颜色匀度及缺陷具有一定的检测效果。Presents an approach of detecting ceramic tile＇s color difference in CIE YU＇V＇ model is presented. It turns image data from RGB model to CIE YU＇V＇ model, then calculates color difference between the standard ceramic tiles and the detected ones using U＇, V＇ variable. The ceramic tile＇s color grade is known from analyzing the average color difference in the whole and the color difference in small areas. The approach is effective in uniform color and defect detection.
