  1. Sound Source Localization using MICs2013/10/21 김성 Multimedia DSP LAB

  2. Counter Sniper Detection System shock wave muzzle blast

  3. 음원 추적 • Sound Source Localization • 2D Space Sound source S • Estimate • from 2 microphone input • 2D 공간상의 음원 방향 인식 Microphone

  4. 2개의 Microphones

  5. 3개의 Microphones

  6. 4개의 Microphones

  7. 2D 음원 방향 및 위치 인식 (x, y) • 이론적으로 최소 3개 microphone 필요 • More microphone for redundant info. • 3D 음원 위치 인식 in (x,y,z) • 최소 3개 microphone pairs(6개) 필요 • 보통 8개 microphone 이상 사용

  8. 실험 환경

  9. 음성 인식

  10. MATLAB • MATLAB 란 ? • MATrix LABoratory

  11. MATLAB 구조 MATLAB Core C. Fortran language
