摘要
本文提出了一种有效的高速公路裂缝边缘快速检测算法。通过将对称指数滤波器(ISEF)算法与边过程算法有机结合的方法,对高速公路裂缝图象进行抑制强烈噪声和微分二值化运算,并利用追踪围线提取得到裂缝边缘。实验结果证明,该方法能稳定有效地提取图象中的连续裂缝边缘,并且运算复杂度是线性的,有利于高速实时的处理。
An efficient high - speed freeway cracks contour detecting algorithm is proposed in this paper. By combining infinite symmetric exponential filter and contour process algorithm, we can suppress intense noise and get binary difference image. Tracing the contour process, we extract cracks contour. The experiment result shows that our algorithm can extract continuous cracks contour efficiently and stably. The computational complexity of our algorithm is linear. It is good at real time realization.
