Problems solved by technology
However, in actual application (such as a face recognition machine in a community), due to the obvious difference in the height of the personnel, it cannot be guaranteed that all personnel can align their faces at the center of the lens, which leads to low recognition efficiency of the access control recognition machine and cannot Give full play to the maximum recognition effect of the access control machine

Embodiment Construction
[0035] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0036] Such as figure 1 with Figure 4 As shown, according to a kind of pan-tilt tracking method based on face recognition described in the embodiment of the present invention, described method comprises the following steps:
[0037] 1) Obtain the image information of the face;
[0038] 2) Recognize the face in the image information;
[0039] 3) Calculate the coordinates of the center point of the rectangular frame circumscribing the face in the target plane area. Specifically, the coordinates of the face frame, x1, y1, x2, y2, can be obtained through the face detection model. Among them, x1, y1 are the coordinates of the upper left corner of the face, and x2, y2 are the coordinates of the lower right corner of the face. The center point of the area can be obtained by these four...

The invention discloses a pan-tilt tracking method based on face recognition, a pan-tilt and an access control recognition machine. The method comprises the following steps: acquiring image information of a face; recognizing a human face in the image information; calculating the coordinates of the central point of the face bounding rectangular frame in the target plane area; and adjusting the calculated coordinate of the central point of the human face bounding rectangular frame in the target plane area to be consistent with the coordinate of the central point of the target plane area. The direction of the lens on the access control recognition machine can be automatically adjusted, the face recognition efficiency of personnel is improved, and the time cost is saved.
Description
technical field [0001] The invention relates to the technical field of access control identification machines, in particular to a pan-tilt tracking method based on face recognition, a pan-tilt and an access control identification machine. Background technique [0002] Limited to certain objective situations, the general access control recognition machine can achieve the most effective recognition of the face recorded in the center of the lens. However, in actual application (such as a face recognition machine in a community), due to the obvious difference in the height of the personnel, it cannot be guaranteed that all personnel can align their faces at the center of the lens, which leads to low recognition efficiency of the access control recognition machine and cannot Give full play to the maximum recognition effect of the access control machine. Contents of the invention [0003] The purpose of the present invention is to propose a pan-tilt tracking method based on fac...
