Abstract

The invention discloses a face tracking method. The method comprises the following steps: acquiring a current frame of picture, a previous frame of picture and face key points in the previous frame ofpicture; calculating the current frame of picture according to a preset face recognition neural network to obtain a first face key point of the current frame of picture; calculating the current frameof picture, the previous frame of picture and the face key points in the previous frame of picture according to a preset optical flow algorithm to obtain second face key points of the current frame of picture; and judging the first face key point and the second face key point according to a preset face tracking judgment condition, and selecting the corresponding face key point as the final face key point of the current frame according to a judgment result. The embodiment of the invention further provides a human face tracking device and equipment, and the problem that in the prior art, humanface key points shake, and consequently tracked human face position information is inaccurate can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a face tracking method, device and equipment. Background technique [0002] At present, image processing technology has been applied to more and more fields. Among them, the face tracking technology based on image sequences is a technology that detects faces from videos and captures information such as the position and size of faces in subsequent frames. However, the current face tracking technology does not take into account the jitter of key points of the face, which leads to the problem of inaccurate location information of the tracked face. Contents of the invention [0003] Embodiments of the present invention provide a face tracking method, device and equipment, which can effectively solve the problem in the prior art that the key points of the face shake, resulting in inaccurate position information of the tracked face. [0004] An embodiment of the pr...
