[0004] Based on this, during the building digital twin construction process, since the model information in the digital twin model is determined based on the initial construction information of the target physical building, some real scenes in the target physical building change (such as interior decoration design changes, room layout changes, personnel flow, etc.), it will lead to distortion of the model information in the digital twin model, which in turn will reduce the user's maintenance and management efficiency of the target physical building

The invention provides a building digital twinning construction method and system, and the method comprises the steps: obtaining to-be-processed image frames from a monitoring video stream of a first building scene frame by frame; performing three-dimensional target detection on the to-be-processed image frame to obtain a three-dimensional pose detection result; carrying out coordinate conversion processing on image position coordinates of each entity object in the three-dimensional pose detection result by utilizing a camera internal reference matrix and a camera external reference of the first shooting device between the pixel coordinate system and the virtual space world coordinate system to obtain entity position coordinates of each entity object in the three-dimensional pose detection result; and updating the first virtual scene model according to the display difference between the three-dimensional pose detection result of each entity object and the first virtual scene model. Therefore, linkage updating can be carried out on the building information model mapped by the target entity building in the virtual space so as to maintain the virtual-real consistency of the entity building and the virtual model, and the maintenance efficiency of a user on the target entity building is improved.
Description
technical field [0001] This application relates to the technical field of architectural digital twins, in particular, to a construction method and system for architectural digital twins. Background technique [0002] Digital twin refers to making full use of data such as physical models, sensor updates, and operation history, integrating multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and completing the mapping in the virtual space to reflect the entire life of the corresponding physical equipment. cycle process. [0003] Specifically, architectural digital twins mean that in the application scenarios of engineering construction, in order to display the spatial layout structure of the target physical building more intuitively and clearly, engineering construction personnel usually construct a model that can reflect the target physical building after the target physical building is completed. The building information mo...
