1. An augmented reality (AR) guiding method applied to an AR device, comprising:
obtaining a real-time surrounding image and a focus of a user's line of sight in the real-time surrounding image;
performing an image recognition process on the real-time surrounding image to obtain a first set of surrounding feature points;
obtaining a marked sample image corresponding to the real-time surrounding image;
screening the surrounding feature points in the first set of surrounding feature points based on the marked sample image to obtain a second set of surrounding feature points;
determining a first surrounding image based on the second set of surrounding feature points, the first surrounding image including at least one image area, and a density of the surrounding feature points in each image area being greater than a density threshold;
determining a guide sign sequence based on the at least one image area; and
displaying at least one guide animation based on the guide sign sequence, each guide animation being used to guide the focus of the user's line of sight from a current guide sign to a subsequent guide sign.
