Problems solved by technology

Especially in the education industry, cameras are basically installed in the classroom to record the classroom situation. The conventional practice is to install a camera at the front of the classroom to record the situation of the students, and install a camera in the middle of the classroom to record the situation. In the case of teachers, the teacher's camera is usually used to record the panorama of the podium area, and it is impossible to achieve close-up recording of the teacher

Abstract

The invention discloses a video tracking method based on face recognition. The method comprises the following steps: 1, when a teacher walks on a platform, a monitoring system detects that the teacher walks on the platform and then a tracking machine is triggered to get into a tracking mode; 2, the tracking machine performs searching through acquired points of a marginal value of the color of an image, performs connection line processing to the points and draws the outline of the head of the teacher through each connection line; 3, both the top of the head and the outline of the face of a person are found out through the connection lines and are matched with the face model preset in the tracking machine; 4, when the outline drawn by the connection lines is matched with the face model preset in the tracking machine, assisting judgment of the skin color of the face and the color of the hair is performed; if requirements are met, the judgment of a face is realized, and the teacher is tracked for shooting. The method can recognize the position of the head of the teacher according to the face recognition technology and performs shooting to the teacher through tracking, so that the close-up record of the teacher is realized, video contents are enriched, and the video effect is optimized.

Description
