Abstract

The invention discloses a real-time image superposition method and device for augmented reality (AR). The following technical scheme is adopted: when a monocular camera photographs a preset scene in real time, the planes in the current key frame and the longest edge line in each plane are determined; and when a virtual image is superposed to a first plane in the current key frame, the fitting faces of the main features in the virtual image are fitted into the first plane, and the forward edges of the main features are set to be parallel or perpendicular to the edge lines of the first plane. Therefore, visual experience of the AR technology can be provided for users without the need to digitize a real environment in advance, the steps before users experience the AR technology are avoided, the real-time performance is strong, and the scope of applications is greatly expanded. Meanwhile, the actual edge of the plane in a real environment is considered, and the authenticity of the main features in the virtual image is obviously improved.

Description

technical field [0001] The present 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 d...
