【摘要】 根据有缺陷混凝土试件温度场差异 ,通过摄影采集混凝土结构洒水后温度和不同时刻含水量变化等参数的图像 ,并经图像处理对传统目视检查难以观察到的裂纹进行初步识别。试验验证该方法是可行的 ,但仍需进一步研究和完善。更多还原

【Abstract】 The water content images of the concrete sample sprayed with water in various periods were photographed and processed to detect the crack hard to be found by visual examination based on the variation of the temperature field of the sample. Experimental result showed that the method was feasible, yet further research and perfection should be made.更多还原
