Intelligent detection and identification method for dangerous building

The invention discloses an intelligent detection and identification method for dangerous buildings. The method comprises the following steps: establishing a building information digital model; the method comprises the following steps: acquiring holographic image data in a building, performing deep learning on various damage characteristics based on a building information digital model, and performing damage characteristic identification on each plane image expanded by the holographic image data to obtain building internal damage distribution information so as to determine building internal dangerous point distribution information; acquiring deformation data of the building through a line laser scanning technology, identifying the deformation data based on the building information digital model, and acquiring deformation distribution information of internal components and external whole bodies of the building so as to determine dangerous point distribution information of the whole deformation of the building;
