Abstract

Sistema automático de vigilancia y seguimiento bidimensional acústico. El sistema objeto de la presente invención permite (i) detectar por procedimientos acústicos en la banda de audio (5Khz- 20Khz) la existencia de objetos en un espacio de vigilancia acotado, (ii) estimar su posición espacial dimensional y (iii) registrar sus trayectorias. El funcionamiento de la invención es enteramente automático: la misión del operador se reduce a definir la sensibilidad, alcance y velocidad de actualización y a lanzar el programa maestro. Básicamente el sistema comprende un equipo de digitalización y registro A/D y D/A (2), (3), (4), un conjunto de transductores constituido por una red estructurada de micrófonos y un altavoz (11), (12), (13), un sistema de amplificación y filtrado analógico (8), (9), (10), un equipo de procesado de señal en tiempo real (5) y un equipo informático de computación (1) dotado del software necesario para el funcionamiento del sistema (6).
