Abstract
This invention provides an acoustic camera comprising a first sound source pick-up device, a second sound source pick-up device, and a switch. The switch is connected to the first sound source pick-up device and the second sound source pick-up device and used to select the first sound source pick-up device or the second sound source pick-up device to reconstruct the sound source of a detected object as a sound field. The first sound source pick-up device has a first microphone array which a uniform-spaced microphone array applicable to a near acoustic field. The second sound source pick-up device has a second microphone array which a non-uniform-spaced microphone array applicable to a far acoustic field.
