Abstract
This application discloses a similarity map search method, apparatus, electronic device, and storage medium. The method and apparatus are applied to electronic devices. Specifically, the method involves standardizing the acquired original PRPD map to be matched using a pre-trained standardization network to obtain a binary semantic segmentation map; extracting multiple relevance parameters from the binary semantic segmentation map; calculating the relevance parameters between the binary semantic segmentation map and each historical PRPD map in a historical map database based on these parameters to obtain multiple map similarities. The historical map database includes multiple historical PRPD maps that have been standardized using the standardization network; and selecting the historical PRPD map with the highest map similarity among the multiple map similarities as the target historical PRPD map similar to the original PRPD map. This solution eliminates the need for manual comparison and search, reducing the need for significant manpower and resources, thereby improving search efficiency.
