Problems solved by technology

[0006] (1) The traditional virtual simulation design requires many basic model splicing, which is cumbersome;
[0007] (2) The existing virtual simulation technology does not pre-study the traffic flow model suitable for highway tunnels and tunnel groups, which leads to the incompatibility of vehicle operation and tunnel section operation rules in other simulation software;
[0008] (3) There is no storage for different facilities with relatively fixed shapes in the operating environ

Example Embodiment

[0048] The key technical route in the present invention is the overall architecture of the highway tunnel and tunnel group operating environment simulation visual system. figure 1 Shown:

[0049] As the most important part of the present invention, the scene library provides all required scenes for the visual simulation of the operating environment, and can realize the visual simulation. Based on the establishment of the visual simulation scene database of the operating environment of the highway tunnel and the tunnel group, first collect data, including the design data of the tunnel and the tunnel group, the climate data of the tunnel and the tunnel group, the field survey data of the tunnel and the tunnel group, and the tunnel and the tunnel group Traffic flow data, and then analyzed the existing research data and then combined the scenes to propose a typical combination scene of the highway tunnel and tunnel group operating environment. The scene content production includes ter...

Description

technical field [0001] The invention belongs to the technical field of computers and relates to the environment visual simulation technology. Background technique [0002] As a brand-new comprehensive information technology emerging at the end of the 20th century, virtual reality technology plays an irreplaceable role in many fields. The feature of virtual reality technology is to use computer multimedia technology to create a simulation environment of the real environment in the computer system, and to simulate the real perception of the human body such as vision, hearing, taste and touch through computer hardware equipment, so that the participants can have the same experience as those in the real environment. same or similar experience. [0003] European and American countries first proposed the basic idea of ​​virtual reality system in the 1960s. In the 1980s, the National Aeronautics and Space Administration (NASA) and the US Department of Defense organized a series o...
