Two dimensional code navigation principle (extracted from Internet):
Mr. Yang: l33-l695-03l0 Weixin 2-D code navigation system with the same number, including a mobile phone, is characterized by including a server system, a 2-D code identification system and a building with a road; the 2-D code identification system includes at least two 2-D code labels; and the server system stores the road of the building. The two-dimensional code label is arranged on the road;
The server system is provided with a map database which stores two-dimensional code association information associated with at least two two two-dimensional code labels and road map information, and the two-dimensional code association information and road map information are associated with each other;]The correlation method is that the two-dimensional code association information and the corresponding two-dimensional code association information are associated with each other. The actual position of the dimension code label on the road is related to the corresponding position on the road map information.
] The mobile phone is equipped with a camera and a two-dimensional code identification software. After taking the two-dimensional code label with the camera and processing the data through the two-dimensional code identification software, the mobile phone is connected to the server system through the network. The server system can find the corresponding two-dimensional code association by calling the map database. The two-dimensional code association information is adjusted to find the position associated with the road map information, and then the actual position of the two-dimensional code label on the road is reflected.
This further reflects the actual location of the mobile phone holder in the building. When you can know your position, you can better optimize the route. Existing conventional navigation systems, such as GPS, Beidou navigation, can not be used in buildings, shopping malls, hotels, plazas and other specific small-scale environments. The invention effectively compensates for the shortcomings of these navigation systems.
The server system generates a map image by correlating the position of the road map information, and sends the map image to the mobile phone through the network. For easy viewing. Mr. Yang: l33-l695-03l0 WeChat No.
Alternatively, the server system generates a text description of the location associated with the road map information and sends the text description to the mobile phone via the network. For easy viewing.
The two-dimensional code tag information is input to the mobile phone, and then another two-dimensional code tag is photographed by the camera, and the information is uploaded to the server system, which searches for the two-dimensional code tags corresponding to the two-dimensional code tags respectively and calls out the two-dimensional code correlation information. Locate the associated location on the road map information;
According to the information in road map information, we calculate the road between two locations. The server system generates the map image by correlating the position on the road map information and the calculated road, and sends the map image to the mobile phone through the network. For easy viewing.
Alternatively, the server system generates a text description of the computed path, and sends the text description to the mobile phone via the network. For easy viewing. The information of the two-dimensional code label input to the mobile phone can be retrieved from the mobile phone file.
The way to retrieve can be retrieved from stored photos. The two-dimensional code recognition software retrieved two-dimensional code label images from stored photos. Users can shoot a two-dimensional code tag in advance, such as shooting the two-dimensional code labels of their own room accessories. When you go back to the hotel and need to find your own room, you can get the route back to your room by shooting two-dimensional code labels in other locations.
The way to get it can also be retrieved from SMS. The two-dimensional code recognition software retrieved two-dimensional code label images from MMS. The user can send the two-dimensional code label photo to his friend near his location. Friends get two-dimensional code label photos from MMS, the two-dimensional code recognition software calls two-dimensional code label images from MMS, and takes a nearby two-dimensional code label, which can get a roadmap or instructions to the user. The way to get it can also be retrieved from the website. The two-dimensional code recognition software retrieved two-dimensional code label images from the website. The two-dimensional code label image of the desired location can be obtained, and then the two-dimensional code label near the neighborhood can be taken to obtain the travel map of the desired location.
