Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITED
Field: Computer technology (Electrical engineering)
Classification: CPC G  Y | IPC G

Claim 14:
15. One or more non-transitory computer storage mediums storing computer readable instructions, the computer readable instructions, when executed by one or more processors, causing the one or more processors to:
detect target feature points of a current video frame in a currently captured video;
calculate a video frame difference value according to pixel coordinates of the target feature points of the current video frame and pixel coordinates of target feature points of a previous video frame;
determine the current video frame as a target video frame in the currently captured video based on the video frame difference value not satisfying a preset change condition;
determine an object area in the target video frame; and
perform augmented reality processing on the object area in the target video frame and augmented reality scene information, to obtain an augmented reality scene,
wherein the computer readable instructions further cause the one or more processors to calculate the video frame difference value based on:
a first difference between a current mean of the pixel coordinates of the target feature points of the current video frame and a previous mean of the pixel coordinates of the target feature points of the previous video frame; and
a second difference between a current variance of the pixel coordinates of the target feature points of the current video frame and a previous variance of the pixel coordinates of the target feature points of the previous video frame, and

wherein the computer readable instructions further cause the one or more processors to determine whether the video frame difference value satisfies the preset change condition by comparing each of the first difference and the second difference with a preset threshold.
