Abstract

The invention provides a slope parameter extraction method and device and a storage medium. The method comprises the steps of obtaining variables of transmission of test signals at to-be-tested positions along a preset direction along with time; obtaining a target coordinate corresponding to each transmission distance in the preset direction; and carrying out fitting processing on the target coordinates corresponding to the transmission distances to obtain slope parameters of to-be-tested positions. According to the scheme, the slope parameters are extracted by adopting the target coordinates,errors caused by noise interference can be effectively weakened, and the accuracy and reliability of slope parameter extraction are improved.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a slope parameter extraction method, device and computer-readable storage medium. Background technique [0002] In ultrasonic elastic imaging, geological exploration, seismic wave detection and other applications to track wave propagation velocity, wave velocity detection is involved, that is, to detect the propagation process of wave features along the propagation direction of interest within a certain period of time. [0003] Currently, image processing is commonly used to extract slope parameters to obtain propagation velocity. Due to the complexity of the wave propagation process under actual conditions, the imaging quality of strain data is usually poor, so the slope parameters obtained by the above existing methods are often inaccurate. Contents of the invention [0004] The present application provides a slope parameter extraction method, device and computer-read...
