摘要
提出了利用数字图像处理技术获取表面分形维数的方法。该方法利用尺码法测量分形维数的原理,对表面轮廓曲线进行二值化处理,并给出基于逻辑像素的寻点算法,并展示了利用数字图像处理技术获取分形维数的实现流程。结果表明,利用图像处理技术,可以保证获取分形维数的准确度在10%左右的误差范围内,而且随着拟合点数量的增加,准确度也随之增加。通过比较,发现基于图像处理的分形维数提取方法具有较好的测量稳定性,而且无需占用太多的计算机资源即可获得较高精度。
A method of acquiring fractal dimension of surface with technology of image processing is presented,which is proposed based on the principle of acquiring fractal dimension with yard method.The image of profile is transformed into an image composed of two logical values.A method of seeking pixel based on the two-logical-value image is given.A flow chart of applying technology of image processing to acquire fractal dimension is displayed.The results suggest that the error using this method lies around at 10%and the accuracy can be improved as the number of fitted points is increased.It can be seen through comparison that the results obtained from this method are more stable,and more accurate results can be measured without occupying much computer resource.
