MULTI-TARGET TRACKING METHOD, APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2020/215552

A1

A multi-target tracking method, a multi-target tracking apparatus, a computer device, and a storage medium, comprising: acquiring an image to be examined containing a plurality of targets (S11); using a preset first detection model to detect head regions in the image to be examined (S12); using a preset second detection model to detect figure regions in the image to be examined (S13); on the basis of the head regions and the figure regions, calculating regional ratios (S14); determining whether a regional ratio smaller than a first threshold is present in the regional ratios, the preset threshold being less than 1 (S15); when a regional ratio less than the first preset threshold is preset, determining that an obstructed pedestrian is present in the image to be examined (S16); on the basis of the head region and the figure region, separating out the obstructed pedestrian (S17); and using a preset tracking algorithm to track the separated obstructed pedestrian and an unobstructed pedestrian (S18). In the present method, tracking targets are determined by means of combining both a head region and a figure region, and said method therefore features an excellent tracking effect when multiple obstructed targets are present.
