Problems solved by technology

[0003] Such a large amount of data is stored in the database. If the database is directly used to search and compare feature data, the performance cannot meet the application requirements.
In actual comparison, even if disk files and memory are used for comparison, the comparison efficiency is still difficult to achieve satisfactory results, and a large number of hardwar

Embodiment approach

[0056] figure 1 It is an embodiment of the data processing method provided by the present invention, including the following:

[0057] Step S101, loading the characteristic data and its information items in the database to a local disk, and creating a current index according to the information items of the characteristic data;

[0058] Step S102, storing the loaded feature data in the local disk according to the current index arrangement to become local feature data;

[0059] Step S103, reading the local feature data into the physical memory to become memory feature data, and the arrangement and storage of the memory feature data is the same as the arrangement and storage of the local feature data;

[0060] Step S104, acquiring a comparison condition, searching the current index in the physical memory according to the comparison condition, and determining that the memory characteristic data meeting the comparison condition is the first characteristic data;

[0061] Step S105...

Abstract

The invention provides a data processing method, which comprises the steps of: periodically loading characteristic data and information items thereof in a database to a local disk, and creating a current index; arranging and storing the loaded characteristic data in the local disk according to the current index to become local characteristic data; reading the local characteristic data in a physical internal memory to become internal memory characteristic data, wherein the arrangement and storage modes of the internal memory characteristic data are the same as those of the local characteristic data; searching the current index in the physical internal memory according to a comparison condition, and determining the internal memory characteristic data satisfying the comparison condition as first characteristic data; and locating the position of the first characteristic data in the physical internal memory. The invention also provides a data processing device used for realizing the data processing method, and the data processing device and method of the invention have the advantages of improving the comparison efficiency and comparison performance of the characteristic data so as to obtain a more accurate comparison result.

Description

technical field [0001] The invention relates to a comparison system, in particular to a data processing method and device in the comparison system. Background technique [0002] With the advancement of technology and the needs of society, the comparison system is gradually widely used in various industries. Since the comparison system is mainly based on the support of data, most of the current comparison systems are large-scale comparison systems or even ultra-large-scale comparison systems, such as the face feature comparison system in the portrait recognition system, and the fingerprint system in the fingerprint system. Feature comparison system. The data storage capacity of the comparison system can generally reach millions or even tens of millions, hundreds of millions, and the size of each piece of data is generally between several KB to tens of KB, so the total amount of data in the comparison system can generally reach Several GB to hundreds of GB. [0003] Such a ...
