Three-dimensional photography monitoring system and method for deformation of buildings

The invention belongs to the technical field of three-dimensional monitoring, and particularly relates to a three-dimensional photography monitoring system and method for deformation of buildings. The three-dimensional photography monitoring system comprises an input module, an image control point measuring module, a data processing module, a monitoring point measuring module and a monitoring point extracting module. The input module is used for inputting information like an image; the image control point measuring module is used for measuring the image space positions of image control points on the image according to photographic device parameters used in the process of acquiring the image; the data processing module is used for acquiring exterior orientation elements and interior orientation elements of the image; the monitoring point measuring module is used for measuring the image space positions of monitoring points on the image according to the photographic device parameters used in the process of acquiring the image; the monitoring point extracting module is used for extracting the coordinates of the monitoring points in a ground space coordinate system and/or a three-dimensional distribution diagram of the monitoring points. By means of the system, the deformation features of buildings can be comprehensively monitored; the system can be applied to monitoring of deformation of buildings.
