The ultrasonic wave device transmits transmission ultrasonic waves toward an object, receives reflected ultrasonic waves, and outputs reception signals. The processor is configured to: detect a transmission time; detect zero-crossing points of the reception signals; detect zero-crossing times; calculate periods of time between the transmission time and each of the zero-crossing times; compare a reference period of time with each of the calculated periods of time so as to generate difference values therebetween; determine a minimum value among the difference values; and set a corresponding zero-crossing point having the minimum value as a reception zero-crossing point. The ultrasonic wave measuring device is configured to measure a distance toward the object based on the period of time between the zero-crossing time corresponding to the reception zero-crossing point and the transmission time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasonic wave measuring device and ultrasonic wave measuring method","description":"An ultrasonic wave measuring device including an ultrasonic wave device and a processor.
