Title:
PERSON DATABASE PARTITIONING METHOD, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/063037
Kind Code:
A1
Abstract:
The present application provides a person database partitioning method and a device. The technical solution of the present application comprises: determining, according to a personnel capture probability of personnel being captured by a first camera, personnel sets that might be captured by the first camera, and determining, according to each of the personnel sets of the first camera, a personnel database partition corresponding to a region. The personnel capture probability can be constantly updated, enabling the people most recently active in the region to be maintained in the person database partitions, thereby significantly reducing inactive personnel data compared to static database partitioning. The invention improves the hit rate of first-time comparison when performing 1:N face identification and real-name labeling, and reduces the need to perform a second comparison operation, thereby achieving low resource consumption and reduced time for comparison.
