The embodiment of the invention provides an elasticity measurement method, device and system and a storage medium. The method comprises the following steps: transmitting a low-frequency vibration signal to a to-be-measured medium; after the emission of the low-frequency vibration signal is stopped for a preset time length, an ultrasonic signal is sent to the to-be-detected medium, so that the ultrasonic signal tracks the low-frequency vibration signal, and the preset time length is greater than or equal to 0; collecting an ultrasonic signal returned by the to-be-detected medium; and determining the elasticity of the medium to be measured according to the returned ultrasonic signal. According to the embodiment of the invention, when the elasticity of the to-be-measured medium is calculated, the influence of interference of low-frequency vibration of the probe on an ultrasonic signal returned by the to-be-measured medium does not need to be considered, displacement compensation calculation does not need to be carried out, the cost of the device is reduced, the calculation complexity is reduced, the calculation time is shortened, and the elasticity measurement efficiency and accuracy are improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of measurement technology, and in particular, to an elasticity measurement method, device, system and storage medium. Background technique [0002] Elasticity measurement is widely used in food industry, medical care and other fields. For example, the elasticity of food can be measured by elastic measurement method to monitor the quality of food; According to the elastic measurement results, it can be determined whether there is a lesion in the part. [0003] In the prior art, the method of elastic detection is to use the probe to generate low-frequency vibration signals to the monitoring object, and at the same time transmit ultrasonic signals to the detection object, and collect the ultrasonic signals returned from the detection object, because the probe will cause the returned ultrasonic signal when generating low-frequency vibrations The reference point of the reference point is changed,...
