Abstract

The invention provides a method and system for realizing an augmented reality map. The method may include the steps: segmenting a planimetric map to generate a segmented image including a road regionand a non-road region; acquiring a shot image corresponding to the planimetric map; extracting feature points of the segmented image and feature points of the shot image; matching the feature points of the segmented image with the feature points of the shot image, and determining matched feature points; registering the segmented image to the shot image in a three-dimensional manner based on the matched feature points, and generating an augmented reality map; and outputting the augmented reality map.

Description

technical field [0001] The present invention relates to the field of Augmented Reality (AR for short), in particular to a method and system for realizing an Augmented Reality map. Background technique [0002] With the rapid development of electronic maps and the emergence of augmented reality technology, the market demand for traditional paper maps is declining. [0003] Augmented reality is an emerging technology that superimposes and calculates camera angles, positions, and corresponding images, videos, and 3D models in real time, which can improve the sensory experience of users interacting with the real world. As an important augmented reality technology, 3D tracking and registration technology can solve the problem of image registration under different conditions such as size, rotation and illumination. [0004] However, the methods for implementing augmented reality maps in the prior art still have many deficiencies, for example, the image processing speed is not goo...
