Feature value ID management method and device, electronic equipment and storage medium

Abstract

Embodiments of the invention provide a feature value ID management method and device, electronic equipment and a storage medium. The method comprises the following steps of obtaining a long feature value ID; generating a short feature value ID corresponding to the long feature value ID, wherein a mapping relationship exists between the long feature value ID and the short feature value ID; establishing a mapping table based on a mapping relationship between the long feature value ID and the short feature value ID; and storing the long feature value ID, the short feature value ID and the mappingtable into a server, and storing the short feature value ID into a GPU. The read-write time consumption of the feature value ID in the GPU can be reduced, and the utilization rate of GPU storage space and the search efficiency of feature search are improved.

Description

technical field [0001] The present invention relates to the technical field of feature search, in particular to a method, device, electronic equipment and storage medium for managing feature value IDs. Background technique [0002] At present, in the search system based on the GPU hardware platform, we save the feature value and the ID of the feature value in the video memory. Since this feature value ID is generally a unique ID value generated by the structural engine, it is used to distinguish each captured portrait. In order to meet the ever-increasing number of snapshots, it is generally stored in the data type of unsigned long integer (range: 0~18446744073709551615), such as figure 1 shown. The range of data represented by this data type has far exceeded the number of eigenvalues ​​that a single GPU card can store. This leads to the following two problems: (1) the eigenvalue ID in the GPU device memory occupies too much storage space, and the utilization rate of the ...
