基于Matlab的图像处理技术在建筑外墙饰面砖中的应用

he security risks of the debond ceramic tile in the external wall is often overlooked,it can cause great threat to the public.The experiment model of debond detection of building defected by infrared thermography is set up, and polystyrene foam is used instead of the external walls of buildings within the hollowing. The obtained images of them are analyzed to calculate the ratio of the empty swell by digital image processing technique ,and compared the final consequence and the experimental design value. It is shown that Matlab is liable to the ratio of the hollowing of the buildings facing tiles and can provide basis for maintaining To maintain and processing the internal hidden danger and the examination promptly plays the part of the face brick the security.
