Automatic Tracking and Recording Using Sound Source Localization for Live Drama Performances

林采穎、蔡予曦

Abstract

Drama recordings shot from a fixed angle are challenging for audiences to follow the plot, as it can be hard for recorders to focus on the performers who are giving lines. This is a problem in the drama competition at our school, where multiple cameras are not readily available. In this research, we proposed a camera system that implemented sound source localization to automatically track and record on-stage performances. The results showed that our system is capable of automatically tracking and recording a sound source.

Methodology

Conclusions and Future Work

An automatic camera tracking system combining hardware and software components is developed. The results showed that despite some weakness toward sudden changes in the target’s motion, the system is able to keep a moving person centered 57% of the time and in the frame 91% of the time. This allows an improved viewing experience for online audiences. To ensure an even better tracking accuracy, it is suggested that the future work be centered on integrating more complex filters into the system.
