Crack detection above buildings based on the infrared thermal imaging technology

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.
