Abstract

A monitoring video generation method applicable to a CT machine, including: acquiring a plurality of primary videos including a monitored target, determining a keyframe according to a region in an initial frame of each primary video surrounding the monitored target, and determining a bounding box surrounding the monitored target in the keyframe; determining, for each primary video, a bounding box surrounding the monitored target in each subsequent frame; and selecting, for each frame moment from the frames of the plurality of primary videos, a frame in which the region of the monitored target within the bounding box has a largest area as the keyframe, and generating a monitoring video in real time according to a part of each selected keyframe located within the bounding box.
