Abstract

The invention discloses a three-dimensional display method for project real-time progress based on a BIM technology and an image overlaying technology. According to the method, first, the BIM technology is utilized to establish three-dimensional simulation models according to collected images of a project construction drawing, a project construction schedule and a construction site respectively; next, the image overlaying technology is utilized to overlay images obtained through a planned progress model and an actual progress model on the same layer; and through comparison of different colorson the same layer, deviation values and other relevant progress parameters of progress are obtained, and three-dimensional display of the project real-time progress is realized. The method has the advantages that all project participants can visually obtain real-time three-dimensional visual construction progress information in a 3D view environment.

Description

technical field [0001] The invention belongs to the display technology of construction progress of a construction project, and in particular relates to a three-dimensional display method of real-time project progress based on BIM and image superposition technology. Background technique [0002] In the existing methods for displaying the progress of construction projects, engineering personnel generally display the progress of the construction site by collecting actual data in the form of bar diagrams. This display method is relatively flat and not intuitive, and it is difficult for non-professionals to quickly understand the bar chart The progress status shown in the figure, especially when facing large-scale and super-large construction projects with many participating units, large scope, long construction period, and complex construction organization process, the existing display methods can no longer clearly describe the progress of construction projects. It also cannot m...
