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 2):
The object detection device of  claim 1 ,\n wherein the processor generates a plurality of items of third sound data having directivity in an arbitrary direction range by sequentially changing a directivity direction range based on the first sound data, generates the plurality of items of second sound data having directivity in the arbitrary direction included in a first direction range by sequentially changing the directivity direction based on the first sound data in a case where the sound pressure level of the specific frequency, which is included in a frequency component of the third sound data having directivity in the first direction range of the arbitrary direction range, is equal to or larger than a second prescribed value, and determines that the object exists in the first direction in a case where the sound pressure level of the 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 the first prescribed value.
