Systems and methods are provided for generating a digital twin representation of an ultrasonic testing environment. In one aspect, probe position data received from one or more controllers and coordinate system data generated by one or more sensors can be used to generate a digital twin representation of an ultrasonic testing environment. In another aspect, generating the digital twin representation can include determining probe position measurements and a plurality of probe paths to be included in the digital twin representation. In one aspect the system can include a vision system to enable remote operation of the ultrasonic testing environment based on the generated digital twin representation.

A detection method based on a battery defect detection system, a system and a storage medium are disclosed. The detection method includes: acquiring a scanning trigger signal, and controlling an ultrasonic transceiver and a motion control platform to work, so that the ultrasonic transceiver receives waveform data of ultrasonic waves passing through a cell; controlling an oscilloscope to collect the waveform data; receiving the waveform data and performing imaging processing to obtain an imaging diagram; and detecting whether or not the cell has a defect according to the imaging diagram.

A transducer element for an ultrasound probed that is disposed on a base block includes a first portion having a first curvature and a second portion having a second curvature with a radius shorter than the first curvature. The transducer element includes an FPC disposed across the first portion and the second portion and a laminate including a transducer disposed on the FPC. The laminate including the transducer includes a layer of a piezoelectric element, wherein the laminate including the transducer includes a relatively shallow groove that does not completely cut the layer of the piezoelectric element and a relatively deep groove that completely cuts the layer of the piezoelectric element, the relatively shallow groove and the relatively deep groove are alternately disposed at a position corresponding to the first portion, and a plurality of the relatively deep grooves are contiguously disposed at a position corresponding to the second portion.
