Problems solved by technology

The accuracy of the recognition effect of this scene recognition outdoors can indeed be guaranteed, but if it is indoors, the GPS positioning system is almost completely ineffective, because the building will block the GPS signal, resulting in GPS positioning failure

Embodiment 1

[0044] figure 2 Shown: a scene recognition method based on indoor positioning and GPS, comprising the following steps:

[0045]Ⅰ. Obtain the user's current location information through the mobile terminal, communicate with the server, and download the area location information within the preset range around the location information and the storage data corresponding to the area location information;

[0046] Ⅱ. Obtain the camera orientation data value and the angle value between the camera and the vertical direction on the mobile terminal through the mobile terminal, as well as the vertical angle value, horizontal angle value and the farthest visible distance value of the camera cone of the mobile terminal;

[0047] Ⅲ. The mobile terminal selects the position information of the pre-display area by using the orientation data value, the included angle value, the vertical angle value, the horizontal angle value, the farthest visible distance value and the judgment method, and fu...

Embodiment 2

[0076] On the basis of embodiment one, figure 1 Shown: The purpose of the 3D projection matrix algorithm is to make the 3D object projected into 2D to produce the effect of far smaller and near larger. Point O(0,0,0) is the camera (the position of the eye), we only display the coordinates in the viewfrustum (view frustum) of the object within the visible range of the mobile phone, and we will not display the objects outside the view frustum to be displayed. Point P1 is closer to point O than point P, then in the display converted from 3D to 2D, the object at point P1 will appear larger than the object at point P.

[0077] image 3 Shown: Two objects are selected for illustration, the actual object 1 is a closer object, the stored information corresponding to the corresponding position corresponds to the text 1, and the position displayed on the screen corresponds to the projection 2; the actual object 2 is a farther object, and the corresponding corresponding position The s...

Abstract

The invention discloses a scene recognition method based on indoor positioning and GPS. The mobile terminal obtains the user's current location information, communicates with a server, and downloads the area location information within the preset range value around the location information and the corresponding area location information. The stored data; the stored data is bound to the location information, and the stored data is stored as the attribute of the location information; the appropriate location information is selected to obtain the stored data bound to the location information; the mobile terminal obtains the video information by calling the camera, And through the 3D projection algorithm, the stored data for display is projected onto the video information for display. The scene recognition accuracy of the present invention is very high, and the recognition speed is very fast.

Description

technical field [0001] The invention belongs to the field of geographic location services, and in particular relates to a scene recognition method based on indoor positioning and GPS. It is an emerging technology that combines the positioning algorithm based on mobile phone Bluetooth 4.0, geographic location information (including location latitude and longitude and location name) and mobile phone sensitive components (electronic compass and intelligent management sensor). Background technique [0002] Due to the rapid development of electronic production technology, the production of processor components and sensor components has reached the nanometer level. With the popularity of networkable devices), more and more functions are integrated on a mobile terminal. People travel with at least one mobile terminal, and when they go to unfamiliar places, they can use the mobile terminal to locate and obtain their location in real time. [0003] When we come to a strange place, ...
