Title:
UNET-BASED SURFACE WAVE FREQUENCY DISPERSION QUALITY RAPID EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/099422
Kind Code:
A1
Abstract:
The present invention belongs to the field of seismic wave data processing, and disclosed is a UNet-based seismic surface wave frequency dispersion quality rapid evaluation method, where: first, surface wave frequency dispersion data is collected, a valid label is manually marked for each frequency dispersion point, and same is divided into training set samples and test set samples; then, a surface wave frequency dispersion quality evaluation UNet model is constructed, and the UNet model is trained by using the training set samples; and last, the rate of change of a frequency dispersion, a surface wave frequency dispersion, and a period are taken as input for the trained UNet model, and a UNet prediction result of the surface wave frequency dispersion after quality evaluation is obtained. The method of the present invention can complete batch frequency dispersion data processing in a short period of time, the method can replace traditional methods and greatly increases processing efficiency compared to traditional manual identification methods, and same lays a foundation for surface wave frequency dispersion real-time inversion.
