Problems solved by technology

[0004] However, in the process of implementing the present disclosure, the inventors found that the AR technology based on image tagging relies heavily on tagged images. When the tagged image is not completely captured, the camera loses its position and cannot combine virtual Content: The accuracy of IMU-based AR technology is low, and the cumulative error will become larger and larger, and the applicable scenarios are limited

Embodiment Construction

[0095] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0096] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood...

Abstract

The invention provides a camera positioning method and device, electronic equipment and a storage medium, and the method comprises the steps of obtaining a current frame image collected by a camera, obtaining a plurality of first feature points from the current frame image, carrying out the matching of the first feature points with a plurality of second feature points in a three-dimensional marker database, and determining second feature points matched with the first feature points, wherein the three-dimensional marker database stores a plurality of second feature points corresponding to one or more three-dimensional markers and three-dimensional coordinates of the second feature points, and the number of the second feature points matched with the first feature points is smaller than the number of the second feature points corresponding to one of the three-dimensional markers, so that the current position of the camera is determined based on the three-dimensional coordinates determined through matching and the two-dimensional coordinates of the first feature points in the current frame image. According to the embodiment of the invention, the accurate positioning process can be carried out by shooting part of the three-dimensional marker, the limitation on the marker in the shooting process is reduced, and the invention has wide applicability.

Description

technical field [0001] The present disclosure relates to the technical field of augmented reality, and in particular to a camera positioning method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] Augmented Reality (AR, Augmented Reality) can combine virtual content into real scenes, use virtual content for visual enhancement, display it through a screen or projection device, and support users to interact with it, which has become a virtual reality It is an important field of research and an important direction for the development of human-computer interface technology. AR technology uses real-time positioning of the spatial position of the device itself to ensure that the virtual content is well combined with the real scene to achieve a sufficient sense of reality. [0003] AR technologies applied to mobile terminals in related technologies are mainly divided into two categories: AR technologies based on image markers and A...
