The invention belongs to the technical field of geophysical
information processing, and relates to a spatial anomaly weight determination method and
system based on
time sequence similarity, and the method comprises the steps: carrying out the data clustering classification of CO
surface concentration original data; obtaining CO abnormal data based on a clustering result; calculating to obtain a Benniov energy accumulation curve; performing abnormal accumulation
processing on the extracted CO abnormal data to obtain an abnormal accumulation curve, and performing normalization
processing on the abnormal accumulation curve and a corresponding Beniov energy accumulation curve; calculating the
time sequence similarity between the normalized abnormal accumulation curve and the Benniov energy accumulation curve; and taking the
time sequence similarity as a target function to obtain an optimized space weight parameter. According to the invention, the spatial weight can be adaptively determined based on the
time structure similarity, the correlation between the anomaly analysis result and the seismic activity is improved, and the method is suitable for seismic correlation
anomaly detection and analysis.
