Abstract
An object detection device includes an acquisition unit that acquires intensity of a direct wave at a second transmission and reception unit among a plurality of transmission and reception units that allow transmission and reception of an ultrasonic wave, the direct wave directly received by the second transmission and reception unit and being an ultrasonic wave transmitted by a first transmission and reception unit among the plurality of transmission and reception units. An intensity of a reflected wave received by the transmission and reception unit, the reflected wave being a reflected wave obtained by the ultrasonic wave transmitted from the first transmission and reception unit reflected on an object, and a detection unit that calculates an air-absorption attenuation coefficient of the ultrasonic wave on the basis of the intensity of the direct wave to detects the object on the basis of the air-absorption attenuation coefficient and the intensity of the reflected wave.
