Abstract
A method for calibrating an ultrasonic sensor includes: transmitting a first ultrasonic signal from the ultrasonic sensor toward a first surface of a contact device when a model is on the first surface of the contact device; generating ultrasonic images by sampling a first ultrasonic echo signal, the first ultrasonic echo signal comprising a reflected signal of the first ultrasonic signal, at a plurality of reception time points; detecting portions of the ultrasonic images, wherein detected portions of the ultrasonic images are most similar to corresponding portions of a reference image of the model compared to other portions of the ultrasonic images having same positions as the detected portions and detected at different reception time points of the plurality of reception time points than the detected portions; and storing the reception time points corresponding to the detected portions of the ultrasonic images.
