Problems solved by technology

[0003] The current monitoring devices that can perform face recognition generally require the identified object to walk in front of the camera for frontal alignment. The user experience is poor, because on the one hand, not all identified objects are willing to align. Active alignment time is slower

Abstract

The invention discloses a face tracking method and device. The face tracking method includes: acquiring an infrared image and a visible light image; detecting the face area of ​​a target object in the infrared image and acquiring the face area in the infrared image The coordinates of the central point of the human face area; according to the coordinates of the central point of the human face area in the infrared image, obtain the corresponding coordinates of the corresponding point in the visible light image of the central point of the human face area in the infrared image; obtain the corresponding coordinates in the infrared image a horizontal angle and a vertical angle of a corresponding point of the center point of the face area in the visible light image relative to the center point of the visible light image; and controlling the rotation of the pan / tilt based on the horizontal angle and the vertical angle, to track the face of the target object. The face tracking method can realize automatic tracking and alignment of the face of the target object, and improve the alignment efficiency and user experience of the target object. This device has similar advantages.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a face tracking method and device capable of automatically tracking the orientation of a face. Background technique [0002] With the development of economy and information technology, the emergence of various monitoring requirements in the fields of access control, security, anti-terrorism, etc., put forward higher requirements for the intelligence of monitoring devices, while the continuous development of computer video image technology and various control processing and The development of communication and other technologies provides conditions for the intelligence of monitoring devices.
