[0030] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0031] See also Figure 1 , a schematic diagram of the structure of a first embodiment of a virtual reality conversion system of the present invention. The virtual reality conversion system comprises:

[0032] The first server 10 is used to obtain the current server map and obtain the range information and location information of the area where the user is located, and convert the range information and location information of the area into first data and second data;

[0033] A second server 20 is connected to the first server 10, and the first server 10 obtains geographic information data of the area through the second server 20 in combination with the first data, and converts the geographic information data into third data;

[0034] The first server 10 obtains the supplementary object data of the area in combination with the second data and converts the supplementary object data into fourth data, so as to form a virtual reality environment through the third data and the fourth data.

[0035] Combination Figure 2 The first server 10 includes: a first acquisition unit 11, used to obtain the range information and location information of the area where the user is located; a first conversion unit 12, connected to the first acquisition unit 11, used to convert the range information and location information of the area into the first data through longitude and latitude coordinates, and the first data is longitude and latitude coordinate data; a second conversion unit 13, connected to the first acquisition unit 11, used to convert the range information and location information of the area into the second data through Mercator coordinates, and the second data is Mercator coordinate data.

[0036] The first server 10 also includes: a second acquisition unit 14, connected to the first conversion unit 12, used to receive the first data from the first conversion unit 12 and acquire geographic information data from the second server 20 and combine the first data with the geographic information data; a third acquisition unit 15, connected to the second conversion unit 13, used to receive the second data from the second conversion unit 13 and acquire supplementary object data and combine the second data with the supplementary object data; a third conversion unit 16, connected to the second acquisition unit 14 and the third acquisition unit 15, used to convert the first data and the geographic information data into the third data through the single-precision floating-point coordinate system recognized by the 3D engine based on NPL, and convert the second data and the supplementary object data into the fourth data, the third data and the fourth data being positioning data and corresponding information represented by the single-precision floating-point coordinate system recognized by the 3D engine based on NPL.

[0037] Combination Figure 3 The first server 10 also includes a rendering unit 17, and the rendering unit 17 is used to render the third and fourth data through a 3D engine based on the NPL framework to form a virtual reality environment.

[0038] Among them, the reference point of the Mercator coordinate system is the intersection of the equator and the prime meridian, the reference point of the coordinate system of the server map is the origin in the upper left corner of the map, which is represented in the real world as an accurate point corresponding to the Mercator projection coordinate system, and the origin of the server map in the first server 10 is associated with the origin in the 3D engine.

[0039] Therefore, the present invention associates the origin of the server map of the first server 10 with the origin in the 3D engine, which can be represented as an accurate point corresponding to the Mercator projection coordinate system in the real world, thereby indirectly associating the 3D engine coordinate system with the Mercator coordinate system, thereby establishing a connection between the virtual world and the real world.

[0040] The first server 10 of the present invention obtains the current server map and obtains the range information and location information of the area where the user is located. The first server 10 includes a first acquisition unit 11, a first conversion unit 12, a second conversion unit 13, a second acquisition unit 14, a third acquisition unit 15 and a third conversion unit 16. The first server 10 obtains the range information and location information of the area where the user is located through the first acquisition unit 11. The first conversion unit 12 converts the range information and location information of the area into the longitude and latitude coordinate data through longitude and latitude coordinates, and converts the range information and location information of the area into the Mercator coordinate data through the second conversion unit 13. The second acquisition unit 14 receives the longitude and latitude coordinate data from the first conversion unit 12 and obtains the longitude and latitude coordinate data from the second server 20. The geographic information data and combines the latitude and longitude coordinate data with the geographic information data, the third conversion unit 16 converts the latitude and longitude coordinate data and the geographic information data into positioning data represented by the coordinate system through a single-precision floating-point coordinate system recognized by a 3D engine based on an NPL framework; the third acquisition unit 15 receives the Mercator coordinate data and obtains the supplementary object data from the second conversion unit 13 and combines the Mercator coordinate data with the supplementary object data, the third conversion unit 16 converts the Mercator coordinate data and the supplementary object data into corresponding object information represented by the coordinate system through a single-precision floating-point coordinate system recognized by a 3D engine based on an NPL framework, and the first server 10 also includes a rendering unit 17, which renders the positioning data and the corresponding object information to form a virtual reality environment.

[0041] The virtual reality environment formed is a 3D world that is exactly the same as the real world. The virtual reality environment is connected to the real world through three sets of coordinate systems (Mercator projection coordinate system, server map coordinate system, and 3D engine coordinate system based on NPL framework), so that the positions of all objects in the virtual reality environment correspond to reality one by one, and they all exist in the real world. Users can seamlessly travel around the entire earth through the virtual reality environment system of the present invention. The flexible conversion of the three sets of coordinate systems prevents the system from switching scenes caused by position deviations. The three sets of coordinate systems are independent of each other, and the switching of the server map will not cause the transformation of the 3D engine coordinate system; at the same time, the three sets of coordinate systems are interrelated, and the position of an object has a unique and determined point in the data corresponding to the three sets of coordinate systems, and finally the objects in the real world are displayed in the form of 3D information, which increases the correlation between the virtual reality environment and the real world and enables users to obtain information more intuitively.

[0042] In this embodiment, the current server map and the supplementary object data are pre-set by the user in the first server 10, wherein the supplementary object data is authentic and can be collaboratively edited, and all information, including the location data of the object, will be jointly supervised by all users to ensure the authenticity of the data; the second server 20 is a Geographic Information System (GIS) server, and the first server 10 obtains the geographic information data of the area where the user is located through the GIS server. The data provided by the GIS geographic information system has the characteristics of authenticity and accuracy, and the GIS geographic information is divided into terrain data and GIS object data. The terrain is represented by a control point every 30 meters, and each control point corresponds to a unique coordinate point and a height value information on the earth. The coordinate point is represented by the Mercator projection coordinate system, and the height value is recorded in meters. GIS objects such as streets, rivers, trees, bridges, culverts, etc. correspond to different data bodies, each of which has a series of coordinate information and point, line and surface descriptions. These data bodies also correspond to unique coordinate points on the earth. Each GIS object represented by the Mercator projection coordinates is the only individual existing on the entire earth. The true performance of GIS geographic information brings users a complete visual experience, allowing users to truly feel that they have entered the earth in our daily lives, where there are familiar landforms, mountains, and rivers.

[0045] Specifically, the range information and location information of the area where the user is located are obtained through the first obtaining unit 11 of the first server 10;

[0046] The first conversion unit 12 in the first server 10 converts the range information and the location information of the area into the first data through the longitude and latitude coordinates, where the first data is the longitude and latitude coordinate data;

[0047] The second conversion unit 13 in the first server 10 converts the range information and the location information of the area into the second data through Mercator coordinates, where the second data is Mercator coordinate data;

[0048] The reference point of the Mercator coordinate system is the intersection of the equator and the prime meridian, and the reference point of the coordinate system of the server map is the origin in the upper left corner of the map, which is represented in the real world as an accurate point corresponding to the Mercator projection coordinate system.

[0049] Step S2: Acquire geographic information data of the area by combining the first data with the first server 10 and the second server 20, and convert the first data and the geographic information data into third data.

[0056] Step S4: forming a virtual reality environment through the third data and the fourth data.

[0057] Specifically, the rendering unit 17 in the first server 10 renders the third and fourth data through a 3D engine based on the NPL framework to form a virtual reality environment.

[0058] The virtual reality conversion system of the present invention is in a 3D engine coordinate system based on the NPL framework, so that no matter where the user goes in the virtual reality environment, he / she is in the real world, and everything he / she sees is real and corresponds one-to-one with the real world, achieving the same authenticity as the real world, and providing users with advance perception services that traditional information interaction systems cannot achieve. Users do not need to go to certain places, but can first understand the appearance of the place through the virtual reality conversion system of the present invention, and use the remote services provided by the system, and the cost will become very low.
