Abstract:
An object detection device includes a microphone array that includes a plurality of non-directional microphones, and a processor that processes first sound data obtained by collecting sounds by the microphone array. The processor generates a plurality of items of second sound data having directivity in an arbitrary direction by sequentially changing a directivity direction based on the first sound data, and analyzes a sound pressure level and a frequency component of the second sound data, and determines that an object exists in a first direction in a case where a sound pressure level of a specific frequency, which is included in the frequency component of the second sound data having directivity in the first direction of the arbitrary direction, is equal to or larger than a first prescribed value.

Claim (Index 6):
An object detection system comprising:\n an object detection device; a first camera; a control device; and a monitor, wherein the object detection device collects sounds using a microphone array that includes a plurality of non-directional microphones, generates a plurality of items of second sound data having directivity in an arbitrary direction by sequentially changing a directivity direction based on first sound data obtained by collecting sounds by the microphone array, analyzes a sound pressure level and a frequency component of the second sound data, determines that an object exists in a first direction in a case where a sound pressure level of a specific frequency, which is included in the frequency component of the second sound data having directivity in the first direction of the arbitrary direction, is equal to or larger than a first prescribed value, and transmits a result of determination of existence of the object to the control device, wherein the first camera images an image which has an omnidirectional angle of view, and wherein the monitor superimposes positional information of the object, which is determined to exist in the first direction, on the image data, which is imaged by the first camera, and displays the superimposed image under control of the control device.
