基于边缘检测算法的混凝土裂纹识别研究

Edge detection of concrete cracks algorithm based on identification

边缘检测在计算机视觉应用中占有很大的作用,图像的边缘检测长期以来都是数字图像处理的研究重点。裂纹检测对混凝土材料是非常重要的,因为混凝土会因为各种内外因素而产生裂纹从而影响建筑的结构安全。对于表面有较多背景细节的混凝土表面边缘检测,用两种不同的方法:基于空间域的和基于数学形态学的梯度边缘检测来对所拍摄到的裂纹图像进行分析。并对比两种不同的方法,选择一种效率和响应比最高的算法,为实际应用提供参考。

Edge detection has a very important application in image processing and computer vision.It introduced and analyzed several methods of edge detection in digital image processing,such as the common algorithm and mathematical morphology,the results of the ex-periments in some commom algorithms were used to detect the concrete crack in the pictures.Finally ,compares each method and indicated the most suitable method for concrete crack edge detection.
