Abstract

The invention discloses a face tracking method, terminal and storage device based on sound-assisted positioning, wherein the method includes: acquiring an image of a scene captured by a camera; judging whether there is a face of a target object in the image; When the face of the target object is detected, collect all the sounds in the scene through the sound collection device; confirm whether there is a target sound feature corresponding to the target object; The spatial position, and then control the camera to align with the spatial position to track the face of the target object. Through the above method, the present application can locate the position of the target through sound when the camera loses the tracked target object, and control the camera to continue tracking the target.

Description

technical field [0001] The present application relates to the technical field of face tracking, in particular to a face tracking method, terminal and storage device based on sound-assisted positioning. Background technique [0002] With the development of video camera technology, the camera has become one of the essential configurations of the computer. The fields of home entertainment, teaching video, intelligent robot and other fields need to use the camera. In order to improve the user experience, the existing camera The recognition and tracking algorithm can realize real-time tracking of faces and focus the camera on the target person. For example, during the recording of teaching videos, lecturers often walk back and forth during lectures, write on the blackboard, walk around or read articles, etc. The camera recognizes the face information of the lecturer and tracks the lecturer to improve the quality of the class. However, when the lecturer quickly moves out of the ca...
