Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention is a navigation system based on monocular vision positioning, relying on real-time registration scene to complete fast tracking of virtual navigation information and real-time rendering of indoor path. The precise location positioning method and the scene configuration method of the indoor route navigation system are introduced below.

[0028] A schematic diagram of the network topology of the indoor route navigation system of the present invention. Including the mobile terminal 7, the mobile terminal 7 includes a mobile camera 1 and a display screen 2, a wireless local area network 3, a remote server 4, and a remote PC 5. The remote PC 5 is provided with a location structure model library, and the location structure model library will include the inside of the indoor building in advance. A picture of the structura...

Abstract

The invention discloses an indoor path navigation method based on mixed reality, wherein a mobile terminal, a wireless local area network, a remote server, and a plurality of remote PC are provided, the mobile terminal comprises a mobile camera and a display screen, and the plurality of the remote PC are connected via a wired network. The method is characterized by comprising the following steps that: 1) a destination is input on the mobile terminal, and the destination is transmitted to the remote PC through the wireless local area network; 2) the mobile terminal forms an image sequence according to a current image captured by the camera, and transmits the image sequence to the remote PC through the wireless local area network; 3) the remote PC sequentially performs three steps such as reliable identification labeling, image sequence matching and position model screening according to the received image sequence to calculate current position information of a user; and 4) the remote PC calculates and forms path navigation according to the current position information of the user and the destination, overlays the path navigation by using a mixed reality technology in a 3D manner, and feeds the overlaid path navigation back to the display screen of the mobile terminal through the wireless local area network.

Description

technical field [0001] The invention designs an indoor path navigation method based on mixed reality, and belongs to the field of path navigation. technical background [0002] With the rapid development of urban construction, all kinds of modern high-rise buildings are crowded with each other, and their internal structures and functions are intricate. When people are in such strange and complex environments and need to find specific goals, such as office buildings, exhibition halls, In indoor areas such as campuses, hospitals, museums, concerts, technical conferences, and large-scale exhibitions, indoor path navigation is particularly important at this time—guiding users who are not familiar with the place to find the route to the destination, and indoor crowds in emergencies Rapid evacuation and emergency rescue, etc. [0003] Chinese patent application No. CN200810060078.7 "Indoor Positioning Method Based on Wireless Sensor Network" discloses a hybrid indoor positioning ...
