<p>The present invention relates to an instructor tracking system using a three-dimensional sensor and, more particularly, to an instructor tracking system comprising: an instructor tracking device to collect instructor state information including position information and behavior information of an instructor by recognizing the instructor from at least one sensor including a three-dimensional sensor and control the operation of a pan tilt zoom (PTZ) camera, which photographs a lecture image, by generating a PTZ control command according to the instructor state information; an image recording device to receive the lecture image, which is obtained by photographing a lecture scene including the instructor, from the PTZ camera, record the received lecture image, and record an educational material content image of a terminal output from a local terminal; and an image control server to provide a video on demand (VOD) service by generating a lecture video through the integration of the lecture image recorded by the image recording device and the instructor state information, and back up the content of the VOD service, the recorded image of the image recording device, and the instructor state information of the instructor tracking device. Therefore, the system of the present invention can provide the VOD service and the backup service by collecting the instructor state information through at least one three-dimensional sensor, generating scenario operation information through the analysis of event information including the behavior information of the instructor, controlling the PTZ camera according to the scenario operation information, automatically recording the lecture image obtained by the PTZ camera, and making the lecture video through the integration of the recorded lecture image and the instructor state information.</p> |
