涂膜防水层厚度现场可视化测量

Visual Measurement of Coating Waterproof Layer Thickness

针对目前常用的涂膜防水层厚度现场测量方式所存在的效率较低、操作不够方便和对防水层完整性有损伤等问题,利用超声B扫描成像方法对涂膜防水层进行厚度检测,根据被检防水层的客观条件和所采集到的图像信号特征,研究了使用图像测量技术实现涂膜防水层厚度可视化测量的算法,并加以实现。实验结果证明了该算法在现场测量涂膜防水层厚度时具有无损性、普适性和直观性。

There are some problems in measuring the thickness of coating waterproof layers, such as low efficiency, less convenient operation and damaging the integrity of waterproof layers. Just because of these faults, using B-scan ultrasonic imaging method to detecting waterproof coating layer, and based on the ob- jective conditions of the seized waterproof layer and the signal characteristics of the collected image, how to visually measure waterproof layer＇s thickness by image measurement technology was studied and realized in the paper. The results showed that the method is non-destructive, universal and intuitive when measur- ing the thickness of coating waterproof layer thickness in the field.
