Title:
NOISE IDENTIFICATION METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/016572
Kind Code:
A1
Abstract:
A noise identification method and apparatus (200), and a device (300) and a storage medium. The method comprises: respectively performing TAUP transformation on water detection component data and land detection z component data, and acquiring the transformed water detection component data and the transformed land detection z component data; determining corresponding first amplitude envelope component data according to the transformed water detection component data, and determining corresponding second amplitude envelope component data according to the transformed land detection z component data (102); determining a corresponding similarity coefficient according to the first amplitude envelope component data and the second amplitude envelope component data (103); performing median filtering processing on the similarity coefficient, so as to determine a corresponding transverse wave leakage noise data interval (104); and determining corresponding transverse wave leakage noise data according to the transverse wave leakage noise data interval and the transformed land detection z component data (105). Noise data is further identified by means of the degree of similarity between amplitude envelope component data, such that the noise data can be effectively identified.
