摘  要:
采用高强度微波处理方法用于木材的功能化改性研究过程中,为了对微波处理效果进行评价,需要了解处理材表面的裂纹特征信息。利用Matlab软件中的图像处理模块,通过编程对微波处理木材表面裂纹的彩色扫描图像进行图像类型转换、图像增强、图像分割及图像形态学处理,提取图像中存在的裂纹,并最终对裂纹数量、长度、面积等信息进行统计,可以实现对微波处理木材表面裂纹状态的科学评价。

摘  要:
In order to evaluate the status of cracks in microwave-treated lumbers during the research of microwave wood functional modification. A method of evaluation the wood cracks based on the Matlab image processing was developed. It was applied to statistically analyze the cracks in microwave-treated lumbers. The method can be used to process pictures of wood cracks taken from scanner. The cracks can be outstanding from other areas after the steps of turning the RGB figures to gray figures,subtracting the background of the figure,adjusting the contrast gradient,thresholding the gray figure. Then write a procedure and run it in the Matlab software,the number,the length,the area and other statistical results of the cracks in the processed figure can be obtained.
