Method for virtually arranging monitoring camera of construction site based on BIM technology

Abstract

The invention discloses a method for virtually arranging a monitoring camera of a construction site based on a BIM technology. The method comprises the steps of building a three-dimensional model of the construction site; importing the three-dimensional model to three-dimensional design model software, thereby forming a spatial three-dimensional model; adjusting a view angle of the spatial three-dimensional model to a monitoring image needed to be monitored, and outputting imaging information and viewpoint information of the current monitoring image; and selecting a corresponding monitoring camera according to the imaging information, determining a mounting position of the monitoring camera according to the viewpoint information, and performing virtual arrangement of the monitoring camera of the construction site. According to the method, reasonable arrangement can be performed through the BIM technology; and the monitoring camera of the construction site is subjected to virtual and reasonable arrangement by utilizing a visualization characteristic and a simulation characteristic of the BIM technology, so that unnecessary waste of materials in a real mounting process is reduced, the mounting speed is increased, and the management cost is reduced.

Description

technical field [0001] The invention relates to a method for virtual arrangement of monitoring cameras on a construction site based on BIM technology, in particular to a method for arranging monitoring cameras at a construction site with large construction sites, many unit projects, and complex surrounding conditions of the projects. Background technique [0002] For the layout of the monitoring system on the construction site, the traditional layout method is to select the location of the monitoring camera by referring to the general layout plan and site survey and simulating the imagination in the brain. The traditional method of arranging the monitoring system has great limitations, because the commonly used cameras are fixed at a certain height and facing a specified direction, and the range of imaging is limited. This kind of picture cannot be specifically simulated by the human brain. In addition, during the construction process, as the main structure gradually rises f...

Problems solved by technology

The traditional method of arranging the monitoring system has great limitations, because the commonly used cameras are fixed at a certain height and facing a specified direction, and the range of imaging is limited. This kind of picture cannot be specifically simulated by the human brain. In addition, during the construction process, as the main structure gradually rises from the ground, it will block some of the objects originally monitored by the cameras, and the brains of one or two unit engineers may still be able to imagine it. If there are more unit projects Coupled with the complexity of the surrounding environment, there are more and more blind spots and obstacles. For this situation, the usual method is to add more surveillance cameras to make up for it. Since it is impossible to specifically simulate the imaging conditions and field of view height of the surveillance cameras, the layout The final effect is often unsatisfactory, resulting in twice the result with half the effort

Not to mention the waste of materials if the monitoring effect is not achieved, it also increases the maintenance cost in the process
