Intelligent Security Camera with Sound Source Localization Technology

1. Content &Characteristic

O In this project we applied a sound source localization (SSL) technique to the existing CCTV cameras and tried to overcome the limitation that the only small area could be monitored in the fixed direction or in the way of manual rotation.

- Our system succeeded in a prompt rotation toward a direction from which an emergent sound has been generated by performing a real-time estimation of both azimuth and elevation angles of sound sources in real 3D environments.

- By adding the sound source classification (SSC) technique, the system not only estimates the direction of sound source but also preferentially monitors the direction of place in which we could predict some events had just happened, and thus it becomes a true intelligent CCTV camera system.

2. Scientific Value

O It is possible to monitor the surrounding environments efficiently with only a small number of cameras by using the complementary characteristics between image sensor and sound sensor.

O we reserved the technique that can estimate in real-time the azimuth and elevation of the sound source in three-dimensional space simultaneously.

O It is the first surveillance system being able to detect sound events that even occurred out of FOV (field of view), or to keep a camera tracking preferentially according to the type of sound source classification.

O With help of video information, high-level information such as moving object detection, tracking, or crash detection could be available.

Economic Effect

O It is possible to give a help in a prompt response to the events of violent crime, such as sexual abuse, school violence, etc., or to prevent the expanding of those cases.

O The ability to estimate sound sources' direction in three-dimensional space is expected to increase the demand and range of applications.

O A new application or service area could be generated by compensation, combination, or fusion of the CCTV-based video security technology and intelligent technology.
