Three-dimensional virtual map visualization engine technology and device based on geographic position

Abstract

The invention discloses a three-dimensional virtual map visualization engine technology and a three-dimensional virtual map visualization engine device based on a geographic position. The invention belongs to the technical field of virtual maps, the invention discloses the three-dimensional virtual map visualization engine technology and device based on the geographic position. Black and white chartlets and textures are used; the identification degree of the three-dimensional virtual model is not influenced while the data size of the three-dimensional virtual model is reduced; reaction speed is accelerated, meanwhile, the live-action completion module is arranged; a user can shoot a video nearby the user at first; then, the visual angle of a user is used in the three-dimensional live-action storage device to read a pre-stored nearby real scene. Compared with the existing live-action model navigation, on one hand, a user sees an actual scene with naked eyes, the identification degree ishigher, and the navigation accuracy is improved, on the other hand, the actual scene information only needs to be read immediately, the process of downloading a scene three-dimensional model is omitted, the dependence on a network is small, data streams are effectively reduced, the navigation speed is increased, and the navigation efficiency is improved.

Description

technical field

[0001] The present invention relates to the technical field of virtual maps, and more specifically, relates to a geographic location-based three-dimensional virtual map visualization engine technology and device. Background technique

[0002] Database (Database) is a warehouse that organizes, stores and manages data according to the data structure. It was produced more than 60 years ago. With the development of information technology and the market, especially after the 1990s, data management It is no longer just storing and managing data, but has transformed into various data management methods that users need. There are many types of databases, ranging from the simplest tables storing various data to large database systems capable of storing massive amounts of data, which have been widely used in various aspects. In the information society, fully and effectively managing and utilizing various information resources is a prerequisite for scientific research ...
