Research on inspection accuracy and application strategy of infrared imaging technology in construction field

Under the background of the era of vigorously promoting green energy-saving buildings, infrared imaging inspection technology, as a non-contact nondestructive testing means, has been widely used in the field of building energy efficiency. However, due to the existence of various influencing factors, so that the infrared imaging instrument measured temperature and the real temperature of the surface of the object deviation, its measurement results can only do qualitative judgment and can not do quantitative analysis, resulting in the application of infrared technology in the field of building energy efficiency limitations. The article is based on the application of infrared technology and the principle of temperature measurement, through the multi-factor comparative experimental testing and analysis , assess the impact of different building materials, detection distance, reflectivity, reflective temperature and building orientation and other factors, which is conducive to improving the accuracy of the application of infrared imaging technology in the field of construction, and to provide engineers with a relatively accurate and feasible application of the guide to the actual engineering applications to do reference.
