Abstract

The invention discloses a real-time image superposition method and device for augmented reality (AR). The method includes the following steps: acquiring video information generated when a monocular camera photographs a preset scene in real time, and determines the key frames in the video information; establishing point cloud data in real time according to the current key frame and the key frame previous to the current key frame; projecting the point cloud data corresponding to the current key frame to the current key frame, and determining the planes in the current key frame and the longest edge line in each plane according to the projection result and the super pixel segmentation result of the current frame; and when superposing a virtual image onto a first plane in the current key frame,fitting the fitting faces of the main features in the virtual image into the first plane, and making the forward edges of the main features parallel or perpendicular to the edge lines of the first plane through setting. Visual experience of the AR technology can be provided for users without the need to digitize a real environment in advance, and the real-time performance is strong.

Description

technical field [0001] The invention relates to the field of augmented reality, in particular to a real-time image overlay method and device for augmented reality. Background technique [0002] Augmented reality (English: Augmented Reality; abbreviation: AR) is one of the hot research topics in the field of machine vision in recent years. Image and video processing algorithms superimpose virtual images on images of the real environment, enabling users to obtain a new sensory experience beyond reality. When superimposing the virtual image on the image of the real environment, it is necessary to obtain a digital model of the real environment in order to ensure the accuracy of the superimposition of the virtual image. [0003] At present, the digital processing of the real environment generally requires pre-processing. For example, first establish point cloud data through a laser scanner or a photo scanner, and then perform corresponding processing on the point cloud data such...
