摘要
利用光弹性实验条纹的颜色特征,结合MATLAB功能强大的图像处理工具箱对光弹实验所得图像进行了处理.实验程序采用RGB颜色空间来表示图像的颜色特征,以灰度调整、中值滤波和强度描述图为工具,对光弹实验图像进行预处理并获取色差值,从而快速、准确地提取出图像中等差及等倾条纹.文中给出了对径受压薄板实验图的处理结果.实验证明,基于MATLAB的光弹条纹提取技术具有编程简单、方便实用的特点.
By using color character of photo-elastic image, the powerful image processing tools of MATLAB program are employed to extract experiment image in the paper. The RGB color space are been used to denote color character of photo-elastic image in the program. Grey-level adjustment, median filtering and intensity description image tools are also be used to preprocess the experiment picture and get the color difference value. The experiment proves that this method has characteristics that programming is simple, convenient to be practical.
