An architectural survey method based on real-time three-dimensional reconstruction technology

The invention discloses an architectural survey method based on real-time three-dimensional reconstruction technology, and relates to the technical field of architectural surveying, which solves the problems of high human cost, low efficiency and unguaranteed measurement accuracy in surveying operation. The invention comprises the following steps: (1) an image capture system being established by using DirectShow to obtain an image source to be reconstructed; (2) building an MFC framework, capturing images in real time, intercepting needed image materials, establishing an visual interface, andproviding a 3D reconstruction model interface; (3) a camera self-calibration model and a algorithm of camera equipment being used to solve camera internal parameters; (4) establishing the 2D image coordinate system-3D world coordinate system reconstruction model, and obtaining the spatial coordinates of the two points to be measured. As the technical scheme of the invention is adopted, the measurement accuracy can be ensu
