Background

Every year, a large number of new generations join all universities, and for each new generation, the new generation wants to know the environment of the universities as soon as possible, but is worried about the absence of tour guides. A sensitive newborn baby often dares not to open the mouth to ask strangers. In order to solve the problem, when a new student enters a school, each university sends a campus paper version map to the new student so that the new student can be familiar with school environment as soon as possible, but the campus environment cannot be displayed on the paper version map specifically and really, paper is wasted easily, and the concept of green energy conservation and environmental protection is not met.

The Augmented Reality (Augmented Reality) technology is a technology for skillfully fusing virtual information and a real world, is widely applied to various technical means such as multimedia, three-dimensional modeling, real-time tracking and registration, intelligent interaction, sensing and the like, and is applied to the real world after virtual information such as characters, images, three-dimensional models, music, videos and the like generated by a computer is simulated, so that the two kinds of information complement each other, and the real world is enhanced.

The invention relates to a campus navigation method based on augmented reality technology, which explains the following embodiments according to the drawings shown in FIGS. 1-2:

the first embodiment is as follows:

as shown in fig. 1, a campus navigation method based on augmented reality technology includes the following steps:

step 3, the campus server receives a request command sent by the intelligent terminal, and sends image, 3D model or video information data of a certain area module after rendering by an AR technology to the intelligent terminal;

The intelligent terminal is a mobile phone or a tablet personal computer, the mobile phone or the tablet personal computer accesses the campus background server through wireless networks such as wifi or 4G, and the campus electronic map is downloaded from the campus background server. The APP client can be installed on a mobile phone or a tablet computer, and the campus electronic map is displayed through the APP client.

The user can download the APP client side in a two-dimensional code scanning mode or through a campus public number.

The APP client side has the functions of real-time positioning tracking, travel recording and travel feedback. The user opens the APP client, can open campus electronic map, inquires its place position information.

In addition, the user can browse the comments, the travel notes and the pictures published by other users through the APP client side and publish the comments, the travel notes and the pictures of the user. Therefore, the user can carry out online interactive communication with other users by utilizing the APP client, and embarrassment in face-to-face communication is avoided.

The campus electronic map comprises two display modes, namely a two-dimensional plane map and a 3D map, and after a user downloads the campus electronic map to the intelligent terminal through the wireless network, the display mode of the campus electronic map is selected according to needs. In addition, the campus electronic map further has the functions of zooming in, zooming out and information query and retrieval, and a user can selectively display an area module image required to be viewed by clicking a certain area module in the campus electronic map, such as a dining room, a dormitory, a teaching building or a supermarket market. Of course, the user may also select the region module image to be viewed in the query retrieval by means of information query retrieval.

When a user selects a certain area module in the campus electronic map and confirms to query the area module AR image, the intelligent terminal sends a request command to the campus background server. And the campus background server sends the image, the 3D model or the video information data of a certain area module after being rendered by the AR technology to the intelligent terminal according to the request command, and then the intelligent terminal displays the enhanced display picture on a front-end page of the campus electronic map.

The image, the 3D model or the video information data of a certain area module in the campus electronic map are rendered by the AR technology through the campus background server, so that the burden of the intelligent terminal can be greatly reduced.

Example two:

with reference to fig. 1 and fig. 2, on the basis of the first embodiment, in order to enable a new campus to plan a route by using a campus electronic map and to go to a destination more conveniently and quickly, the campus electronic map further includes a route planning module and a speech synthesis module, the route planning module is configured to plan a shortest travel path for a user according to a closest distance priority principle, and the speech synthesis module stores speech interpretation audio data of an area module of the campus electronic map in advance.

The user can input the position information of the area module in the campus electronic map to be searched and inquired on the campus electronic map, and the position information is set as an end point, and then the position information of the user in real time is set as a starting point by the campus electronic map. And after the starting point and the end point are set, automatically calling a route planning module by the campus electronic map to plan the shortest traveling path for the user.

The intelligent terminal, such as a mobile phone or a tablet computer, is provided with a positioning module, so that the route distance between the starting point and the ending point can be calculated and updated in real time, and the distance between the starting point and the ending point is displayed on the campus electronic map in a plain text manner. At this moment, the campus electronic map can call the voice synthesis module according to the selection of the user, and the route distance between the starting point and the ending point is broadcasted through the earphone or the loudspeaker.

In order to enable a user to know the campus environment in real time on the spot and quickly integrate into campus life of colleges and universities, when the user goes to a certain area module, the camera of the smart phone can be used for collecting image data of the area module of the campus electronic map in real time, and then the image data is transmitted to the campus background server.

After analyzing and judging the image data by using an image recognition and matching technology, the campus background server feeds back the information of the area module corresponding to the image data to an intelligent terminal, such as a mobile phone or a tablet computer, and then the intelligent terminal calls a voice synthesis module in a campus electronic map according to the received information of the area module corresponding to the image data to perform voice explanation on the information of the area module.

Example three:

this embodiment is substantially the same as the second embodiment, except that: the intelligent terminal is a mobile phone, the mobile phone has a screen splitting function, and a two-dimensional plane map and/or a 3D map can be displayed according to a user request.

The mobile phone can display a two-dimensional plane map and/or a 3D map in a split screen mode, and is more humanized. The new map with weak sense of direction can be given, and the sense of direction can be enhanced by comparing the two-dimensional plane map and the 3D map through split screens.
