Embodiment 1

[0036] Such as figure 1 , as shown, a UWB and BIM automatic synchronization method for scene and model images, through the installation of high-precision positioning chips including UWB, electronic compass, and gyroscope in the camera, when shooting images, the location information of the images, The orientation vector information, time information and image are bound, and the viewpoint corresponding to the camera is mapped to its actual position and orientation in real time in the construction BIM model of the same image progress, and the actual image of the same position and image progress corresponds to the viewpoint image in the virtual 3D model , to achieve model-based on-site quality checking and progress control.

[0037] A method for automatically synchronizing scene and model images of UWB and BIM, the specific steps are as follows,

[0038] (1) Install a high-precision positioning chip including UWB in the photographic equipment;

[0039] (2) Install electronic com...

Embodiment 2

[0054] An urban complex project in a coastal city in my country. The total construction area is about 180,000 square meters, with 2 floors underground, and the underground area is about 80,000 square meters. Due to the large underground area, the GPS and GNSS signals in the underground space are very poor, but the space is empty, which is suitable for UWB positioning. In this project, the construction BIM model of the project was first established, including civil engineering, electromechanical, steel structure and Site layout BIM model. Revit software is used to build models for civil engineering and electromechanical disciplines and site layout, Tekla software is used for steel structure disciplines, Rhino software is used for curtain wall disciplines, and the models of the four disciplines and site layout are assembled into one model using Revit software. Complete the establishment of the overall model. Arrange UWB positioning base stations at appropriate locations of bui...

Abstract

The invention discloses an on-site and model image automatic synchronization method based on UWB and BIM. Virtual reality of a construction site is constructed by utilizing BIM; a high-precision positioning chip containing UWB and an electronic compass and gyroscope are additionally arranged in a camera, mapping of real images and virtual space images at the same position is achieved, on-site construction management of real-time tracking and management is conducted on on-site construction quality and progress, and on-site quality checking and progress control based on a model are achieved. Compared with other positioning systems, the method provided by the invention is more suitable for indoor field and model image synchronization, especially basement areas.

Description

technical field [0001] The invention relates to the field of building construction management, in particular to an automatic synchronization method for on-site and model images based on UWB and BIM. Background technique [0002] There are many BIM-based methods for comparing the site with the model, but the comparison between the site image and the model requires manual search for the location. When there are too many images or the site is similar, finding the location becomes a difficult task. The patent of the present invention is mainly aimed at the synchronous development of the images of the scene and the model. Since most construction areas are indoors, and indoor GPS or GNSS signals are poor, precise positioning cannot be performed. [0003] Therefore, the present invention adopts UWB positioning technology in terms of indoor position positioning. Since UWB can meet the precision and timeliness requirements of construction management for object positioning in terms o...
