Feature library management method and device, equipment and medium

The invention provides a feature library management method, which comprises the steps of generating an ID of a first feature vector, determining a mapping relationship between the ID of the first feature vector and a storage address of the first feature vector, and storing the first feature vector, wherein the ID of the feature vector is used as an index of the feature vector, and the index does not change along with the change of the storage address. In the subsequent retrieval and deletion process, the storage address of the to-be-deleted vector and the ID of the feature vector matched with the retrieval vector can be obtained through the mapping relation between the ID of the feature vector and the storage address of the feature vector, so that the feature vector is deleted and retrieved, the management difficulty of the feature library is reduced, and the management efficiency of the feature library is improved. 本申请提供了一种特征库的管理方法，包括：生成第一特征向量的ID，确定第一特征向量的ID与第一特征向量的存储地址的映射关系，存储第一特征向量。其中，特征向量的ID作为特征向量的索引，该索引不
