Abstract

The invention relates to a target tracking method, device and equipment applied to classroom recording and broadcasting and a medium, and relates to the technical field of modern teaching systems, and the method comprises the steps: obtaining a teacher area panoramic video and a student area panoramic video; according to the coordinates of the moving target in the panoramic video of the teacher area, performing constant-speed tracking matting on the moving target in the panoramic video of the teacher area to obtain a close-up video of the teacher area; and performing variable-speed tracking matting on the moving target in the panoramic video of the student area according to the coordinate of the moving target in the panoramic video of the student area to obtain a close-up video of the student area. According to the invention, the recorded teacher close-up video picture and student close-up video picture are more stable.

Description

technical field [0001] The present application relates to the technical field of modern teaching systems, and in particular, to a target tracking method, device, device and medium applied in classroom recording and broadcasting. Background technique [0002] At present, classroom recording and broadcasting has been widely used in modern teaching systems, and classroom recording and broadcasting has become an essential device for evaluating teachers' teaching level and strengthening students' learning content. In order to achieve multi-angle and all-round monitoring and recording of teaching activities, traditional classroom recording and broadcasting devices mostly use multi-camera shooting. A single classroom usually needs to be equipped with multiple cameras such as teacher panorama, teacher close-up, student panorama, and student close-up. [0003] At present, a new method of classroom recording and broadcasting has emerged. Two cameras are used to shoot the teacher's pan...
