摘要
针对建筑物表面裂缝的探测问题,设计了一种通过红外热成像技术检测建筑物表面温度,从而进行裂缝探测的方法。该方法分别使用Matlab和仪器附带软件对外业采集的热像图进行相关处理,增强裂缝显示效果,达到探测目的,简化了图像处理流程。需要指出的是,文中所述探测方法以水为介质。为了验证该方法的有效性,对杭州市某小区有裂缝的建筑物进行了探测实验,结果表明该理论与方法具有一定的实用价值。
Aimed at solving the problem of crack detection on buildings, the author has designed a method of crack detection based on the temperature observation above buildings by using the infrared thermal imaging technology. The method utilizes Matlab and other software to conduct related processing of thermal images collected by external industry so as to enhance the display of cracks, thus achieving the purpose of detection and simplifying the image processing process. An analogue experiment on a chapped building in Hangzhou was carried out to examine the reliability of this method. The experimental results show that the theory and method put forward by this paper have some practical value.
