A 3D visualization method and system for monitoring components

Abstract

The present invention provides a 3D visualization method and system for monitoring components, the method comprising: partitioning the processed 3D building information model in the 3D visualization monitoring system; configuring a corresponding 3D positioning module for the monitoring component, and monitoring The corresponding relationship between the component and the 3D positioning module is bound and stored; after the monitoring component with the 3D positioning module is installed at the designated location of the building, the positioning module is 3D positioned and calibrated through the 3D positioning gateway to complete the monitoring component. Locating and obtaining 3D positioning information, the 3D positioning gateway uploads the basic information of the monitoring components and the 3D positioning information to the 3D building information model of the 3D visual monitoring system for visual display. The invention realizes the automatic input of the 3D position of the monitoring element in the 3D visual monitoring system and the update of the 3D position of the monitoring element in the 3D visual monitoring platform, and also proposes a specific positioning algorithm, which reduces the number of positioning base points.

Problems solved by technology

[0002] Underground space structures, such as subway tunnels and high-speed rail tunnels under construction, have the characteristics of complex spatial dimensions, relatively closed space environment, and poor mobile network signal coverage. The existing satellite positioning system cannot accurately monitor components in underground space structures. 3D positioning, so in the underground space structure monitoring system, there are problems such as poor overview of monitoring objects and local visualization, inaccurate location information of monitoring components, and real-time interactive update of the location information and status of monitoring components in the monitoring system, etc.

[0003] The 3D position information of the existing monitoring components in the 3D visual monitoring system is mainly recorded through on-site measurement, and then entered into the 3D visual monitoring system of the monitoring platform through manual input. The position information is wrong and missing. At the same time, due to the 3D position labeling of the monitoring components by the method of later input, real-time update during the monitoring process cannot be realized. For example, during the construction of the subway tunnel, the positions of some monitoring components are often moved. In the existing system, it is difficult to update the 3D position of the monitoring components in real time, let alone realize the status monitoring and classification management of the monitoring components.

[0004] At present, the positioning in the existing technology is generally based on three or four base points, which requires many positioning base points, and the calculation process is complicated, which affects the efficiency of positioning, and due to the limitation of the underground space structure, the number of positioning base points is limited, so the existing The positioning method is also not suitable for the application in the monitoring system of underground space structure
