1. An active interaction method, comprising:
acquiring a video shot in real time;
extracting a visual target from each image frame of the video, and generating a first feature vector of each visual target;
for each image frame of the video, fusing the first feature vector of each visual target and identification information of the image frame to which the visual target belongs, to generate a second feature vector of each visual target;
aggregating the second feature vectors with the same identification information respectively to generate a third feature vector corresponding to each image frame; and
initiating active interaction between an intelligent device and its surroundings in response to determining that the active interaction is to be performed according to the third feature vector of a preset image frame.
