Problems solved by technology

[0004] Therefore, the technical problem to be solved by the embodiment of the present invention is that in the prior art, due to the long-time manual investigation of the identities and criminal information of the control personnel and related personnel, and the appearance of the investigated personnel can only be recognized by memory and eyes, its work The volume is huge, the speed is slow, it cannot meet the needs of the business, and it is often prone to errors

Embodiment 1

[0045] This embodiment provides a method for identifying associated personnel, such as figure 1 shown, including the following steps:

[0046] S11. In the preset area around where the target person appears, obtain the face image features of the person to be identified, and record the time, position and number of times that the person to be identified appears in the preset area. The target person here can be a fugitive who is suspected of being criminally investigated by the public security organ, and is the object of the blacklisted target tracking by the public security organ; the preset area is to monitor by installing multiple cameras near the area where the target person often moves The deployment and control area constituted is the preset area; the person to be identified here is an associated object that may be related to the target person, and needs to be identified and confirmed; the person to be identified uses multiple cameras to collect his face images to obtain inf...

Embodiment 2

[0061] This embodiment provides an identification device for associated personnel, such as image 3 shown, including:

[0062] Obtaining module 31, is used for in the preset area around that target personnel appears, obtains the face image feature of the person to be identified, and records the time, position and the number of times that the person to be identified appears in the preset area;

[0063] Generating module 32, is used for generating the feature identification of the person to be identified according to face image features, time, position and times;

[0064] The first judging module 33 is used to judge whether the feature identity is associated with the target person;

[0065] The second judging module 34 is used to determine whether the number of times in the feature ID exceeds a set threshold when the feature ID is associated with the target person;

[0066] Alarm module 35 is used for generating an alarm signal to the feature ID when the number of times in the...

Embodiment 3

[0075] This embodiment provides a computer-readable storage medium on which computer instructions are stored, and when the instructions are executed by a processor, the steps of the method in Embodiment 1 are implemented. The storage medium also stores the target person's identity feature, face feature, time of appearance, and location feature information, as well as information on the feature identity mark of the person to be identified.

[0076] Wherein, the storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM), a random access memory (Random Access Memory, RAM), a flash memory (Flash Memory), a hard disk (Hard DiskDrive, Abbreviation: HDD) or solid state disk (Solid-State Drive, SSD), etc.; the storage medium may also include a combination of the above types of storage.

[0077] Those skilled in the art can understand that all or part of the processes in the methods of the above embodiments can be implemented through computer pro...

Abstract

The invention discloses a recognition method and device for associated persons. The method comprises the steps of obtaining facial image features of persons to be recognized within the preset region around a target person, and recording the appearing time, position and frequency of the persons to be recognized within the preset region; according to the facial image features, time, position and frequency, generating feature identity identifiers of the persons to be recognized; judging whether the feature identity identifiers are related to the target person or not; when the feature identity identifiers are associated with the target person, judging whether the frequency of the feature identity identifiers is larger than a preset threshold or not; when the frequency in the feature identity identifiers is larger than a set threshold value, an alarm signal is generated for the feature identity identifiers. For the surroundings of the target person, the persons to be recognized around the target person are monitored, and the associated features of the target person and the persons to be recognized can be rapidly recognized, so that partners of the target person are rapidly tracked, and the case handling efficiency of public security organization is improved.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a method and device for identifying associated persons. Background technique [0002] With the intensification of my country's reform and opening up, there are more and more people entering and exiting the country, and there are more and more personal information. Departments such as border defense and border defense often need to identify and authenticate the identities of relevant personnel, and the information of relevant personnel is very important. Make full use of a large number of existing portrait databases of agencies to speed up the identification process of relevant personnel by relevant departments, thereby providing effective assistance for the work of agencies. [0003] At present, the traditional identification process can only be judged by manual methods. Because it takes a long time to investigate the identity and criminal information of the pers...
