Abstract

Embodiments of the present invention provide a face tracking method and device. The face tracking method includes acquiring face key points and depth features corresponding to the current face image to be tracked as the first face key points and the first depth feature; obtain the face key point and depth feature corresponding to the reference face image as the second face key point and the second depth feature; calculate the distance between the first face key point and the second face key point the first distance, and calculate the second distance between the first depth feature and the second depth feature; determine whether the first distance and the second distance meet the first preset requirement, if the second distance is satisfied If a predetermined requirement is met, it is determined that the face tracking is successful. The embodiment of the present invention integrates face key points and depth features to perform face tracking, which can adapt to face tracking in different complex environments and ensure the reliability of face tracking.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to a face tracking method and device. Background technique [0002] Face monitoring is used in more and more practical scenarios such as community access control and subway security check, especially in the aspects of stability maintenance and anti-terrorism, and mobile personnel control. However, in the existing face monitoring process, due to the randomness of personnel flow, situations such as turning the head, bowing the head, and blocking often occur, which makes the general face tracking method invalid in such cases, resulting in a large number of Mistakes and multi-shots will affect the follow-up face comparison, recognition and tracking. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a face tracking method and device to improve the above problems. [0004] A preferred embodiment o...
