基于数字图像处理技术的建筑裂缝测量研究

Research on the Construction Crack Measurement Based on Digital Image Processing Technology

提出一种建筑裂缝测量方法,即利用普通数码相机采集裂缝数字图像,经过图像预处理、图像分割、像素标定、宽度测量,完成建筑裂缝测量。本文利用Matlab实现该种建筑裂缝测量方法,并通过在理想状态下进行的模拟试验结果,证明该测量方法能达到实际建筑裂缝监测工程中的精度要求。

This thesis puts forward a kind of building crack measuring method, which completes construction cracks measurement by using common digital camera acquisition crack digital image, after the image preprocessing, image segmentation, pixel calibration, and width measurement. This thesis researches on the realization of the measurement methods of construction cracks, and proves that this method could reach the monitoring accuracy of the actual construction cracks after the ideal condition simulation experiment.
