BIM simulation and aerial photography combined construction management and control method and system

Abstract

The invention discloses a BIM simulation and aerial photography combined construction management and control method and system. The method comprises the following steps of outputting a BIM three-dimensional model of a building; according to demands for information acquisition, selecting a characteristic coordinate point needed to be tracked and recorded in advance on the BIM three-dimensional model; an unmanned aerial vehicle arriving at the corresponding position matched with the selected characteristic coordinate point of the entity building, collecting entity engineering characteristic information, and sending the collected entity engineering characteristic information to a monitoring computer; establishing an entity three-dimensional model on the monitoring computer with the entity engineering characteristic information of the same positioning coordinate point which is sent to the monitoring computer by the unmanned aerial vehicle; matching, associating and comparing the entity three-dimensional model with the BIM three-dimensional model of the same characteristic coordinate point in one-to-one manner, automatically finding "matched" and "unmatched" items of the both models, and outputting a project completion comparison report. The system and the method can timely, conveniently and accurately master the construction progress and the construction effect of the building entity, the construction progress can be integrally regulated and controlled conveniently, the construction period is shortened, and the profit is improved.

Description

technical field [0001] The invention relates to the application field of the combination of BIM three-dimensional model and aerial photography, in particular to a construction control method and system combining BIM simulation and aerial photography. Background technique [0002] In the field of large-scale building construction, several construction groups are usually required to undertake the construction in different areas. The manager needs to coordinate and monitor the progress of each construction area as a whole, and make the progress of each construction team consistent as much as possible. On the basis of ensuring construction quality shorten the construction time. In the existing technology, the physical engineering information (not limited to time, quality, progress, safety, construction practices, etc.) Drawings, etc. classify the corresponding engineering information one by one, the work is cumbersome, and the recording method is relatively backward. The projec...

Problems solved by technology

In the existing technology, the physical engineering information (not limited to time, quality, progress, safety, construction practices, etc.) Drawings, etc. classify the corresponding engineering information one by one, the work is cumbersome, and the recording method is relatively backward. The project manager cannot timely, conveniently and accurately grasp the overall progress of the building entity and the construction progress and construction effect of different construction areas. Time is the cost. The phenomenon of corporate financing is common. If the project progress is shortened and the project is completed beyond expectations, the company can get back the funds in advance

On the contrary, if the construction period is delayed due to the inconsistency of the overall construction schedule, it will bring huge economic losses
