Embodiment 1

[0049] Such as figure 1 As shown, an indoor navigation method based on virtual reality technology, including:

[0050] S1. Indoor 3D map, the 3D map is marked with points of interest and contains 360° VR real-scene images, and the 360° VR real-scene images correspond to the points of interest one by one;

[0051]One of the ways to draw the indoor 3D map in this step is: combine the architectural CAD drawing information and the actual environment on site, and draw according to an appropriate scale; mark points of interest on the 3D map, and select key points in the actual indoor activity space to shoot 360° VR real scenes The image, the key points correspond to the points of interest marked on the 3D map, and then the captured 360° VR real-world images and points of interest are stored in the indoor 3D map in one-to-one correspondence.

[0052] In this step, the point of interest can be marked in the following manner: the 3D map and the indoor actual activity space are divided...

Embodiment 2

[0079] Such as figure 2 , this embodiment provides an indoor navigation system based on virtual reality technology corresponding to Embodiment 1, including:

[0080] The map module is used to store an indoor 3D map, the 3D map is marked with points of interest and contains 360 ° VR real scene images, and the 360 ​​° VR real scene images are in one-to-one correspondence with the points of interest;

[0081] One of the drawing methods of the indoor 3D map in this module is: combining the architectural CAD drawing information and the actual environment of the site, drawing according to an appropriate scale; marking points of interest on the 3D map, and selecting key points in the actual indoor activity space to shoot 360°VR real scenes The image, the key points correspond to the points of interest marked on the 3D map, and then the captured 360° VR real-world images and points of interest are stored in the indoor 3D map in one-to-one correspondence.

[0082] The method of marki...

Abstract

The invention discloses a virtual reality technology-based indoor navigation method and a system and belongs to the technical field of indoor navigation. The navigation method comprises the followingsteps: confirming a position of a user terminal by establishing an indoor 3D map containing a 360-degree VR real image and interesting points and by matching a real-time image shot by the user terminal with the 360-degree VR real image; confirming the shortest route from a starting point to a destination according to an A* algorithm, thereby planning a navigation route. A navigation system comprises a map module, an image acquisition module, a rectification module, a position acquisition module, a processing module and a guiding module. The virtual reality technology-based indoor navigation method and system do not rely on other additional equipment and can solve the problems of low efficiency and low accuracy of the present indoor navigation technology.

Description

technical field [0001] The present invention relates to the technical field of indoor navigation, and more specifically, to an indoor navigation method and system based on virtual reality technology. Background technique [0002] With the development of mobile communication technology, people's determination of location has gradually shifted from flat maps to electronic maps. At the same time, it is becoming more and more common to use mobile terminal equipment to obtain current location information and navigation. Among them, the use of mobile terminal equipment and electronic map software for outdoor positioning and navigation technology has been relatively mature, such as: Baidu, AutoNavi, Tencent, etc., which have significantly improved the convenience of people's travel, but due to large high-rise buildings and their interior The complex structure of the indoor space has limited the existing positioning and navigation technology, and the indoor navigation technology has...
