Title:
TARGET TRACKING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/215865
Kind Code:
A1
Abstract:
A target tracking system and method. The target tracking system comprises an image processing unit (1) and a target tracking unit (2). The target tracking unit (2) adjusts the update speed of a target tracking parameter by reading the brightness, chroma and sharpness of each frame of image which are subjected to the statistics of the image processing unit (1), or the chroma and brightness of each frame of image subjected to the statistics thereof, and by means of the calculated current motion information of a tracked object, and determines, according to the statistical information of the image processing unit (1), whether it is necessary to switch tracked features used by the target tracking method; and if so, reads sharpness information of images acquired by the image processing unit (1) so as to switch the tracked features. In this way, the robustness and accuracy of target tracking are improved by means of the combination of the image processing unit (1) and the target tracking unit (2).
