Problems solved by technology

[0003] The traditional ID card (passport) information identification is only effective when the ID card is presented. Criminals (especially the most wanted criminals in the world) generally do not use their own ID cards or passports, so this method has relatively large limitations;
[0004] Infrared cameras do play a very good role in assisting identification, but generally speaking, criminals are also familiar with this threat to themselves, and they will subconsciously cover their faces to escape when entering and exiting airports, stations, ports, etc. (hereinafter referred to as important entrances and exits). The information is captured by the camera, so this method also has certain limitations

Embodiment 1

[0044] A multimodal criminal identification method based on footstep information disclosed in one or more implementations includes:

[0045] The stage of establishing the footstep information database: when establishing the footstep information database, each person's footstep information should be associated with the person's valid certificate (ID card, passport, etc.) information;

[0046]Everyone has a different gait when they walk normally, including stride length, stride frequency, ground contact time, and the angle between the foot and the ground when they are in contact with the ground, etc. Sound data is unique, just like each person's fingerprint is unique.

[0047] At important entrances and exits (such as: airports, stations, ports, etc.) to register personnel footstep information (including: vibration information generated by footsteps hitting the ground and sound information generated by footsteps hitting the ground), for each passing person, the footstep informat...

Embodiment 2

[0065] In one or more embodiments, a multi-modal criminal identification system based on footstep information is disclosed, including a server, the server includes a memory, a processor, and a computer program stored on the memory and operable on the processor , the processor implements the following steps when executing the program:

[0066] (1) Establish a footstep information database, collect personnel's footstep information at the set entrance and exit, associate the footstep information with the personnel's identity information, and save it in the footstep information database;

[0067] (2) Collect footstep information at the set entrance and exit, and match the collected footstep information with the data in the footstep information database; perform face recognition at the same time; set the entrance and exit to refer to the probability of criminal suspects such as airports, stations or ports Larger entrances and exits;

[0068] (3) If the identity information of the ...

Embodiment 3

[0074] In one or more embodiments, a computer-readable storage medium is disclosed, on which a computer program is stored, and when the program is executed by a processor, the following steps are performed:

[0075] (1) Establish a footstep information database, collect personnel's footstep information at the set entrance and exit, associate the footstep information with the personnel's identity information, and save it in the footstep information database;

[0076] (2) Collect footstep information at the set entrance and exit, and match the collected footstep information with the data in the footstep information database; perform face recognition at the same time; set the entrance and exit to refer to the probability of criminal suspects such as airports, stations or ports Larger entrances and exits;

[0077] (3) If the identity information of the person can be obtained through face recognition, go to step (4); otherwise, go to step (5);

[0078] (4) If the person's identity...

Abstract

The invention discloses a multimodal criminal identification method and system based on step information. The method includes such steps of registering personal footprint information at entrance and exit, registering personal footprint information corresponding to personal ID information in footprint information database for each passer-by, and retrieving his information in footprint information database next time he passes by. At that set entrance and exit, the step vibration information and the sound information of each pas person are transmitted to the step information database for search and matching in real time, and the face recognition technology is supplemented to synthesize the identification information of the person. If a match cannot be retrieved, the footprint information is registered for it to update the footprint information database in real time. The invention overcomes the limitations of identification document recognition and simple facial recognition, and can help the public security department to better locate and hunt criminals in the global scope.

Description

technical field [0001] The present invention relates to the technical field of person identification, in particular to a multimodal criminal identification method and system based on footstep information. Background technique [0002] In today's world, the number of crimes is still high every year, and new crimes emerge in endlessly. In many cases, the identity of the criminal or suspect has been confirmed, and the difficulty is how to search for it on the earth. [0003] The traditional ID card (passport) information identification is only effective when the ID card is presented. Criminals (especially the most wanted criminals in the world) generally do not use their own ID cards or passports, so this method has relatively large limitations; [0004] Infrared cameras do play a very good role in assisting identification, but generally speaking, criminals are also familiar with this threat to themselves, and they will subconsciously cover their faces to escape when entering ...
