Through the integration of BIM technology and GIS, complementing each other, and expanding the application on the powerful geographic information system, we realize the technical operation of the fine structure building model, which greatly improves the completeness of the project information, and expands the application scope of the engineering digital products.

In view of the hidden nature of underground works, and covered in the complex surface environment, our institute on the ground and underground model object display style and interaction mode research, and strive to highlight the main body in different scenarios, while maintaining the surrounding environment of the expression of clear.It also prioritizes interaction objects and develops efficient pointer hovering and selection schemes.

Built-in reporting display module, through the scene editing, global roaming, free viewpoints, decomposition review, graphical model superposition and other functions, to achieve high-quality three-dimensional visualization of the report, significantly reducing the threshold of understanding, and improve the efficiency of program expression.

The reporting and display module can also be used for construction briefing and deconstruction observation of the model; based on MR technology + ITO system, it supports the construction inspection of real model consistency, on-site recording of inspection problems, online interactive annotation, etc.; together with the video monitoring equipment + positioning system + AI recognition technology, it can realize the identification of outsiders, tracking of the movement trajectory of the living body, and the management of the construction personnel, etc., in order to improve the safety system of the construction site.
