Face tracking area limiting method based on wide depth parameter

Abstract

The invention relates to the technical field of intelligent image processing, in particular to a face tracking area limiting method based on a wide depth parameter, which is applied to a camera with a face tracking function, and mainly comprises the following steps: acquiring a picture and camera parameters acquired by the camera; face recognition is carried out on the picture collected by the camera, a portrait in the picture is selected, and coordinates of the portrait are obtained; receiving a breadth parameter and a depth parameter input by a user; judging whether the user starts a tracking range limiting function or not; when the tracking range limiting function is started, if the coordinates of the portrait are within the tracking range, determining that the portrait is an effective tracking target; and when the camera recognizes that the effective tracking target begins to speak and / or move, outputting a close-up picture of the effective tracking target as a tracking picture. The target tracking interference elimination method is suitable for target tracking interference elimination in open conference rooms and glass partition scenes, and the application flexibility of the intelligent conference equipment in dynamic complex scenes can be improved.
