A Navigation Method Based on Augmented Reality IP Map

technical field

The invention relates to a navigation method based on an augmented reality IP map.

Background technique

Augmented Reality (AR for short) is a new technology developed on the basis of virtual reality. It is a technology that increases the user's perception of the real world through the information provided by the computer system, applies virtual information to the real world, and superimposes the virtual objects, scenes or system prompt information generated by the computer on the real scene, so as to realize the enhancement of reality . AR is usually implemented in the form of a combination of a see-through head-mounted display system and a registration (positioning of user observation points and computer-generated virtual objects in the AR system) system.

Application number 2013100071800.8 provides an Internet-based "virtual-reality" composite space positioning system; application number 201410299650.0 provides a virtual-reality integrated three-dimensional display method and system.

In the navigation process, especially in the urban navigation process, one of the biggest difficulties is the problem of short-distance positioning (usually the last 200 meters). It often happens that you have arrived near the destination but still can’t reach it accurately, and you can’t find the microscopic and precise location of the target, such as intersections, building numbers, house numbers, room numbers, etc. The above information is often blocked by various buildings and is difficult to find through vision.

Currently, there is no navigation method or system that combines augmented reality technology with IP maps. There is still a lack of effective means for short-distance navigation, and we can only rely on traditional methods such as local people asking or being greeted by the other party, which has great limitations.
