Title:
TRACKED TARGET DETERMINATION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/057309
Kind Code:
A1
Abstract:
A tracked target determination method and a related device, which are applied to an electronic device. The method comprises: acquiring a first image and a second image from the same target video file, and acquiring N first tracking frames of the first image (101), wherein the first image is a previous preset frame image of the second image, and the first image and the second image both comprise N tracked targets; inputting the second image into an hourglass network model to perform feature extraction, and outputting a target feature map (102); inputting the target feature map into a prediction network so as to output a thermodynamic chart, a width and height value set, and a feature vector set (103); determining N second tracking frames on the basis of the thermodynamic chart and the width and height value set (104); determining N first correlations on the basis of the N first tracking frames, the N second tracking frames, and the feature vector set (105); and determining, on the basis of the N first correlations, tracked targets selected by means of the N second tracking frames (106). The method can improve the precision of determining tracked targets.
