Visual positioning digital map ar navigation system and method

Abstract

The visual positioning digital map AR navigation system and method relate to the field of navigation technology, including a data collection module, a digital map generation module, an analysis module, a navigation module, and a display module. After obtaining the data of the area to be navigated, the digital map generation module constructs the data of the virtual area to be navigated corresponding to the real area to be navigated according to the data of the area to be navigated, and maps the objects in the virtual area to be navigated to obtain the digital map data. The image data in the navigation area is characterized by analysis and positioning with the digital map data at the same time to obtain positioning data. The navigation module plans the route according to the positioning data and the calibrated end point coordinates, without relying on GPS and other systems, and determines the current position by identifying the physical object And plan the route, which solves the problem that the current navigation system is prone to poor signal reception, which leads to difficulties in positioning and navigation.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a visual positioning digital map AR navigation system and method. Background technique [0002] With the development of technology, navigation devices can be used to plan routes at any time when going out to play, such as: shopping in large shopping malls, traveling to scenic spots, etc. However, the environment of large shopping malls and scenic spots is very complicated. If you are not familiar with the environment Or the lack of correct guidance routes, it is not only very difficult to reach the destination quickly, but also easy to get lost. At present, the navigation technology mainly uses positioning systems such as GPS to achieve the purpose of positioning, and it can provide better navigation and navigation in places with better signals. Positioning effect, but in places with weak signals, precise positioning and navigation cannot be performed, and it is easy to get lo...

Problems solved by technology

[0003] The embodiment of the present invention provides a visual positioning digital map AR navigation system and method. The data of the area to be navigated is collected in advance by setting the data acquisition module, and the data of the area to be navigated is obtained by calculation. The digital map generation module is based on the data of the area to be navigated. The data constructs the data of the virtual area to be navigated corresponding to the area to be navigated, and maps the objects in the virtual area to be navigated to obtain digital map data. The analysis module collects the image data of the area to be navigated for feature analysis and at the same time analyzes and locates with the digital map data. After obtaining the positioning data, the navigation module plans the route according to the positioning data and the calibrated end position coordinates, without relying on GPS and other systems, by identifying the physical object, determining the current position and planning the route, which solves the problem of easy signal reception in the current navigation system Bad Problems that make positioning and navigation difficult
