Virtual reality technology-based in-building navigation system

Abstract

The invention relates to a virtual reality technology-based in-building navigation system, which comprises a three-dimensional simulation system, a strapdown inertial navigation system and a virtual reality display system; the strapdown inertial navigation system comprises an electronic compass, a gyroscope accelerometer and a barometer, and is used for acquiring the positioning information of a user, including orientation information and attitude information; the three-dimensional simulation system is used for three-dimensional modeling on a building structure and a scene, for coordinate transformation of the positioning information input by the strapdown inertial navigation system, for adding the positioning information into three-dimensional building information subjected to the three-dimensional modeling, and then outputting a processing result to the virtual reality display system so as display the processing result to the user. The virtual reality display system receives the processing result output by the three-dimensional simulation system, displays to the user, and is used for the display and navigation of a virtual scene.

Description

technical field [0001] The invention relates to a navigation system, in particular to a fire scene navigation system in a building based on virtual reality technology. Background technique [0002] With the development of our country's economy, the structure of urban buildings presents a trend of high-rise and complex development. When a fire broke out, the fire site was filled with smoke and visibility was low. It was difficult for firefighters to identify where they were in the building (especially if they were not familiar with the building structure), and it was impossible to quickly locate the specific location of the fire and the trapped people. The location of personnel, coupled with complex building structures, chaotic scenes, and long evacuation distances, all of these have caused huge obstacles to search and rescue, delayed rescue time, not only caused loss of life and property for the victims, but also endangered the safety of firefighters.

Problems solved by technology

When a fire broke out, the fire scene was filled with smoke and visibility was low. It was difficult for firefighters to identify where they were in the building (especially if they were not familiar with the building structure), and it was impossible to quickly locate the specific location of the fire and the trapped people. The location of personnel, coupled with complex building structures, chaotic scenes, and long evacuation distances, all of these have caused huge obstacles to search and rescue, delayed rescue time, not only caused loss of life and property for the victims, but also endangered the safety of firefighters. Personal safety

[0003] Due to the complex internal situation of the building, it is a common problem that fire smoke affects fire rescue, and even endangers the lives of firefighters in severe cases.
