Abstract

The cameraman plays a vital role in e-learning classroom, which provides the focal scene to broadcast automatically according to the on-the-spot instruction context. However, the existing cameramen have some drawbacks in meeting the relevant requires, especially in tracking the sound objects. Thereby, we present a sound-directed cameraman, which can track the sound object and captures his/her focal video in a compelling precision automatically according to users' demands beforehand. Besides, it owns a good few merits, such as switching scene video fluently, facility in setting the shooting demands, flexibility for calibrating.
