Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Specific embodiments of the map augmented reality system of the present invention:

[0020] The software and hardware environments and tools involved in the development of the map augmented reality system of the present invention are as follows:

[0021] The system is developed using OpenCV, OpenGL ES, Android SDK, OpenCV for Android SDK and other tools. The 3D terrain model used in the system is made with 3D Max, and the database uses MySQL database.

[0022] OpenCV (Open Source Computer Vision Library) is a computer vision library used to implement functions such as image matching and pose calculation in prototype systems, and OpenGL ES (Open Graphics Library for Embedded Systems) is a development tool for three-dimensional graphics rendering for mobile electronic devices. To run the map augmented reality system on the mobil...

Abstract

The invention relates to a map augmented reality system, which belongs to the field of map information display and comprises a four-layer structure, namely a user layer, a functional layer, a bottom layer library and a database layer, the user layer provides a map and map information service for a user, provides a map and map information service for the user, and comprises a mobile equipment map augmented reality system initialization module; the functional layer comprises a tracking registration module, a virtual-real combination module and a man-machine interaction module, and the tracking registration module obtains key frames from video streams through a camera and carries out image matching and pose calculation; the bottom layer library is constructed through OpenCV and OpenGL ES, and rendering of virtual information such as a three-dimensional model and the terrain is achieved on mobile equipment; the database layer comprises template map images, three-dimensional models, pictures, characters and video and audio data. According to the method, the deep learning technology, the augmented reality technology and the mobile development technology are combined, and the form and content of geographic information expressed by the paper map and the interaction performance are expanded and improved.

Description

technical field [0001] The invention relates to the field of map information display, in particular to a map augmented reality system. Background technique [0002] Augmented Reality (AR, Augmented Reality) is a technology that uses virtual objects to enhance the reality of real scenes. Augmented reality retains the user's actual environment as the user's main perception and interaction environment, by annotating virtual generated information such as text, two-dimensional graphics, and three-dimensional models on the objects displayed on the display screen in the user's actual environment , so as to realize the annotation and description of the user's environment, or the effect of augmenting the reality environment. For example, if a user wears special augmented reality display glasses and visits a museum in person, when viewing a certain cultural relic, he can not only see the cultural relic and its surrounding environment itself, but also see the image of the cultural rel...
