Abstract Promoting the development of urban chimney damage detection technology is of great
significance to structural repair and urban style renewal． In order to promote the development of chimney
，
defect detection and damage recognition technology in the process of urban renewal based on a defect-
， � �
detection project in Shanghai UAV Unmanned Aerial Vehicle imaging technology was used to complete
， ， ，
the image acquisition image processing modeling of the chimney structure and defect identification
process in four steps． The results show that the 3D reconstruction model acquired based on UAV imaging
，
technology can comprehensively record the characteristic info
