Title:
TARGET TRACKING METHOD AND APPARATUS, ELECTRONIC DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/232652
Kind Code:
A1
Abstract:
A target tracking method and apparatus, an electronic device, and a computer-readable storage medium, which relate to the technical field of computer vision. The specific solution involves: performing target detection on a current frame of image to obtain first information of a target detection box, wherein the first information represents a first position and a first size (101); performing target tracking by using Kalman filtering, so as to obtain second information of a target tracking box in the current frame of image, wherein the second information represents a second position and a second size (102); performing fault-tolerant correction on a prediction error covariance matrix in the Kalman filtering, so as to obtain a corrected covariance matrix (103); calculating the Mahalanobis distance between the target detection box and the target tracking box in the current frame of image according to the first information, the second information and the corrected covariance matrix (104); and performing association matching on the target detection box and the target tracking box in the current frame of image according to the Mahalanobis distance (105).
