红外热像技术在建筑外墙检测中的应用技巧

摘要

在建筑墙体质量检测中，应用红外热成像技术的关键之一在于把握目标体与背景物之间的温度场差异。经验表明，选择适宜时机，合理利用阳光、风、雨水等自然条件，可以显著增强目标体与背景区域间的差异，从而增强影像分辨率，达到准确识别外墙质量甚至是细小质量问题的目的。%In the test of architecture exterior wall, the key to apply infrared thermal imaging technology is to grasp the difference between target object and background object of temperature field. Experience indicates that the selection of appropriate period and reasonable employment of natural conditions like sunshine, wind and rainy water, etc. can outstandingly increase the difference between the target object and background region, thereby enhancing image resolution and realizing the goal of accurate identiifcation of exterior wall quality and even tiny quality problem.
