BIM-based unmanned aerial vehicle monitoring method and system

Abstract

The invention provides a BIM-based unmanned aerial vehicle monitoring method and system. The method comprises a real scene operation step, an unmanned aerial vehicle positioning step and a work condition positioning step. According to the real scene operation step, an unmanned aerial vehicle is operated, an image collection instruction is transmitted to the unmanned aerial vehicle, and real scene images collected by the unmanned aerial vehicle according to the image collection instruction are obtained. According to the unmanned aerial vehicle positioning step, an unmanned aerial vehicle image collection position is generated in a three-dimensional BIM model, wherein the unmanned aerial vehicle image collection position is the position of the unmanned aerial vehicle in the three-dimensional BIM model at a real scene image collection moment. According to the work condition positioning step, a work condition position can be obtained according to the unmanned aerial vehicle image collection position. According to the BIM-based unmanned aerial vehicle monitoring method and system of the invention, the unmanned aerial vehicle and the BIM model are combined together, so that information obtained through aerial monitoring can be recorded, displayed and pushed through the BIM model, and therefore, the working efficiency of monitoring personnel can be enhanced, and manpower can be greatly saved, and the shortening of a construction period can be benefitted.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles and the field of BIM application, in particular to a BIM-based unmanned aerial vehicle monitoring method and system. Background technique [0002] BIM is the abbreviation of Building Information Modeling, that is, Building Information Modeling. It is a kind of building life cycle information management technology. Include the process in the 3D model for simulation, making the model available to workers at any stage of the building's entire life cycle. With the rapid development of drone technology, the degree of automation and intelligence has been greatly improved. The use of drones to replace manual monitoring of construction projects can achieve more accurate real-world monitoring, and the combination of simulation monitoring makes monitoring work more convenient and practical.

AI Technical Summary

Problems solved by technology

Its disadvantages are: it is difficult to conduct large-scale, global, and multi-angle monitoring of the building's exterior, overall, and building overlooking angles, and video monitors need to be pre-set. It is not suitable for monitoring building facades and construction sites that are constantly changing structures. Video surveillance The device occupies the construction space, the confirmation and notification of the position of the working condition stays at the drawing stage, and it is impossible to clearly display the working condition and compare the building components

[0009] (1) Real scene monitoring: Manual survey is not comprehensive and meticulous. When manual observation of a floor finds a problem with a certain floor, it is necessary to go to that floor to check in detail, which requires a lot of manpower. It is even more important to grasp the dynamic information of the project progress in time. difficulty

[0010] (2) Simulation and simulation: Traditional project documents use two-dimensional graphic design drawings, which cannot be compared with physical buildings very well, and it is also a waste of time to carry a large number of drawings around for reference. Different groups of people need to read different files, which wastes a lot of time and manpower

On the contrary, delays in the construction period will bring huge economic losses

Furthermore, the project is affected by many factors such as weather and climate, and traditional monitoring methods have seriously slowed down the progress of the project.
