Target motion trail generation method and device based on monitoring video

The invention relates to a target motion track generation method and device based on a monitoring video, computer equipment, a storage medium and a computer program product. The method comprises the steps that a current detection video frame is acquired from a monitoring video based on the current frame interval number, and the frame interval number between the current detection video frame and a previous detection video frame meets the current frame interval number; performing target tracking detection based on the current detection video frame and the historical detection video frame to obtain a target tracking detection result; determining the current movement speed of the target object according to the position information of the target object in the current detection video frame and the historical detection video frame; updating the current frame interval number based on the current movement speed of the target object to obtain a new current frame interval number; and generating a motion track of the tar
