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...

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 environment of expressway tunnels and tunnel groups, so the model cannot be reused, which reduces the modeling efficiency of the simulation scene;

[0009] (4) The existing virtual simulation technology for highway tunnels mainly focuses on the basic scene roaming and the research on the simulation of a certain traffic control strategy, and lacks the overall visual simulation including the environment inside and outside the tunnel, equipment information, and equipment control. sex studies
