Hybrid Method to Identify AR Target Images in Augmented Reality Applications

摘要

A method for detecting an augmented reality (AR) target image and retrieving AR content for the detected AR image is disclosed. The method is performed at a computer system having one or more processors and memory for storing programs to be executed by the one or more processors. The method includes receiving data of the AR target image. The method includes detecting, based on the data of the AR target image, a group of markers on the AR target image. The method includes calculating a set of cross ratios based on the group of markers. The method also includes retrieving, based on the set of cross ratios, AR content associated with the AR target image. The method further includes displaying the retrieved AR content and the AR target image in a single AR scene.
