Abstract

The invention provides a tracking duration determination method and device, a storage medium and an electronic device. The method comprises the steps of determining an identifier of a first tracking object located in a target area, tracking duration of tracking the first tracking object and shooting time of the Nth frame of image in an Nth frame of image obtained by performing video monitoring on the target area; determining that a first tracking object does not exist in the target area in the M-th frame of image obtained by performing video monitoring on the target area; determining an identifier of a second tracking object appearing in the target area and the shooting time of the O-th frame image in the O-th frame image obtained by performing video monitoring on the target area; and under the condition that the first tracking object is matched with the second tracking object, determining the tracking duration for tracking the second tracking object in the O-th frame image as a second duration. According to the method and the device, the problem of inaccurate calculation of the tracking time length of the undetected object is solved, and the effect of accurately determining the tracking time length is achieved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method and device for determining a tracking duration, a storage medium, and an electronic device. Background technique [0002] In the prior art, when using images to track objects in a queue, only the tracking continuity is used to determine the tracking duration of the tracking objects. [0003] When the tracking object is not detected, it is determined whether it is the same tracking object according to the overlapping area ratio of the tracking frames in the front and rear tracking images. Or by comparing the similarity between the detected potential object and the tracked object, it is determined whether they are the same tracked object, so as to realize the relocation of the tracked object. [0004] It can be known from the above that the calculation of the tracking duration of an undetected object in the prior art is not accurate. [0005] For the problems existing in...
