Abstract
A method, an apparatus, a computing device, and a computer-readable storage medium for monitoring use of target item are disclosed. The method includes obtaining a RoI of each of video frames, for each frame, determining whether the target item and a head of a monitored target object are both present in the RoI, if yes, determining whether a hand of the monitored target object is present in the RoI, if the hand not present, determining a face orientation of the monitored target object to determining whether the each frame is in a first video frame status, if the hand presents, determining a relative position relationship between the hand and the target item to determining whether the each frame is in the first video frame status, and based on a number of video frames continuously in the first video frame status, determining whether the monitored target object uses the target item.
