摘要
针对人工视觉测量桥梁裂缝方法存在的种种弊端,提出基于数字图像处理的桥梁裂缝测量的新算法。首先对采集到的裂缝图像进行数学形态学腐蚀处理,接着进行区域生长,将腐蚀后的图像二值化、细化,得到裂缝中心线,以中心线上的点为种子点向原图裂缝的两边缘逼近,进一步处理就可以得到裂缝的长度和宽度等参数。
To overcome the various of disadvantages of the manual visual measure method of bridge crack, a new algorithm is put forth on the basis of digital image processing technology. First the mathematical morphology processing is used to erode the obtained image of crack. Then grow the area, transform the eroded image into binary image and thin it to obtain the center line of the crack. Starting from the seed point on the center line to approach to two side edge the parameters such as length and width of the crack can be obtained after further processing.
