摘　　要：针对现有的沥青路面裂缝图像边缘检测算法存在的缺点,提出了一种基于图像处理技术的沥青路面裂缝图像边缘检测的新算法。首先分析沥青路面裂缝图像的特征,然后利用整数阶微分和分数阶微分,推导出有理数阶微分,再与Soble算子相结合得到了新算法。最后通过实例验证,并进行定位精度实验和客观评价验证了该算法的有效性。Aiming at the shortage of image edge detection algorithm of existing asphalt pavement crack, a new algorithm based on image processing technology of asphalt pavement crack image edge detection has been proposed. Firstly, analyze the image features of asphalt pavement cracks; secondly, deduce rational order differential by utilizing integer and fractional differential order differential, and work out a new algorithm with Soblearithmetic. Finally, verify the effectiveness of the algorithm by example verification and positional accuracy and objective evaluation experiments.
