Claim 7:
8. A system for implementing an augmented reality scene, the system comprising:
at least one memory configured to store computer program code; and
at least one processor configured to access the at least one memory and operate as instructed by the computer program code, the computer program code including:
target video frame determining code configured to cause the at least one processor 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; and 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;
object area determining code configured to cause the at least one processor to determine an object area in the target video frame;
augmented reality processing code configured to cause the at least one processor to perform augmented reality processing on the object area in the target video frame based on augmented reality scene information, to obtain the augmented reality scene,

wherein the target video frame determining code is further configured to cause the at least one processor 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 program code further includes determining code configured to cause the at least one processor 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.
