摘要
针对彩色带花纹瓷砖色差缺陷人工检测效率低,而且稳定性差的问题,提出一种对彩色带花纹的瓷砖色差检测算法。文中的研究对象是静止摆放的彩色带花纹瓷砖,对其进行了多次实验。首先对采集到的瓷砖图像进行色彩空间转换,对转换后图像的V分量进行中值滤波处理,接着对滤波后的V分量图像进行二值化处理,然后对处理后的瓷砖样本图像进行灰度直方图分割,选择最合适的阈值将彩色带花纹瓷砖从背景图像里分割出来,最后再对分割出来的瓷砖进行分析。经过多次实验可知,该方法对处理彩色带花纹瓷砖色差缺陷效果显著。
In order to solve the problems of low efficiency and poor stability for detecting the chromatic aberration defects on the color patterned ceramic tile,a color difference detection algorithm for the color patterned ceramic tiles is proposed. The research object of this paper is the statically-placed color patterned ceramic tiles,and the related experiments for the ceramic tiles have been carried out. In the algorithm,the color space conversion is performed for the acquired ceramic tile image,the median filtering processing is conducted for the V component of the converted image,the binarization processing is accomplished for the filtered V component image,and then the gray histogram segmentation of the processed tile sample image is performed to select the most suitable threshold value to segment the color patterned ceramic tile from the background image. The segmented tile is analyzed. The conclusion got in the experiments shows this method has a remarkable effect on the processing for the color difference defects of the colored ceramic tiles with patterns.
