Device and method for calibrating relative position of camera and ultrasonic probe in ultrasonic detection

The invention discloses a device and a method for calibrating the relative position of a camera and an ultrasonic probe in ultrasonic detection. The device comprises a measuring water tank of ultrasonic detection equipment, the ultrasonic probe, a signal generator, the camera and a calibration sample which is fixed in the measuring water tank of the ultrasonic detection equipment; the ultrasonic probe is connected with the signal generator; the signal generator emits a pulse signal with certain frequency to the ultrasonic probe, the pulse signal is converted into an ultrasonic signal under the conversion action of the ultrasonic probe and reaches the surface of the calibration sample through a coupling medium; the camera is used for determining the center position of the calibration sample; the overall range of the calibration sample can be watched through the camera; and the calibration sample is the basis for calibration of the relative positon of the camera and the ultrasonic probe.
