Abstract:
A multi-target tracking method includes: obtaining a first image and a second image including N tracking targets from the same target video file, and obtaining N first tracking boxes of the first image that precedes a preset number of frames of the second image, the N first tracking boxes configured to frame the N tracking targets in the first image; superposing and synthesizing the first second images to obtain a target image; inputting the target image into an hourglass network model for feature extraction, to output a target feature map; inputting the target feature map into a prediction network to output a thermodynamic diagram, a width and height value set, a minor deviation value set, and a feature vector set; determining N second tracking boxes configured to frame N tracking targets in the second image, based on the thermodynamic diagram, the above three sets, and the N first tracking boxes.
