Embodiment Construction

[0042] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0043] Such as figure 1 As shown, a face detection and tracking method includes the following steps:

[0044] A. The speed dome moves to the area of ​​interest;

[0045] B. Collect images according to the current dome screen and perform face detection on the images to determine the initial position of the face frame rect(x, y, w, h) of each frame of image;

[0046] C. Calculate the range of the upper body of the person according to the initial position of the face frame obtained in step B, and use the range of the upper body of the person as the feature extraction learning area;

[0047] D. Carry out face frame tracking on the feature extraction learning area of ​​step C according to the KCF target tracking algori...

Abstract

The invention relates to a face detection tracking method, a dome camera head rotation control method, and a dome camera. The face detection tracking method comprises steps: acquiring an image and performing face detection on the image to determine the central position of a face frame of each frame image; and adjusting the central position of the face frame and the central position of the image, and enabling the central position of the face frame and the central position of the image to be overlapped to realize tracking of the face in a tracking frame of a current frame image. According to theface detection tracking method, the false detection rate can be reduced, and the accuracy of face detection is improved. According to the dome camera head rotation control method, face detection is performed by employing the face detection tracking method, the smoothness of the robot head in a rotating process can be guaranteed, and the phenomenon of slow running in the rotating process is avoided.

Description

technical field [0001] The invention belongs to the field of face recognition, and in particular relates to a face detection and tracking method, a ball machine head rotation control method and the ball machine. Background technique [0002] In the prior art, the dome camera automatically tracks the target according to the characteristics of the target according to the background modeling of the shooting picture or the target detection algorithm. Its disadvantage is that it cannot maximize the zoom with the target, and cannot achieve the secondary focus of the target, resulting in the target face resolution being too low for face recognition comparison. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a face detection and tracking method, a dome camera head rotation control method and the dome camera, so as to realize shooting and detection of the clearest human face. [0004] The technical scheme that the presen...
