Search System with Baggage Search and Face Recognition function as one}

The present invention relates to a retrieval system used for baggage retrieval at an airport, etc. More specifically, a camera is installed at the top of the baggage retrieval to simultaneously capture images of baggage and baggage carriers to search for dangerous goods contained in the baggage. In addition, the present invention relates to a baggage retrieval system that combines baggage retrieval and face recognition functions to quickly detect the risk of baggage carriers.

In general, airports, conference halls, and public buildings have a lot of firearms and dangerous goods that can be used for various crimes due to the large number of people entering and exiting. Will be done.

At this time, as a field of a searcher mainly used for the inspection / search, when searching for a hydrate of a hydrate-carrying particle having a hydrate (hereinafter referred to as a `` cargo-carrying particle ''), X-rays are projected onto the hydrate and the X It is well known that a baggage detector is used that enables the identification of contents as an image signal derived from lines.

However, since most of the baggage carriers are cleverly hidden in their baggage in consideration of the fact that various firearms, explosives, etc. are difficult to carry in their bodies, the search for the baggage must be made in particular.

In recent years, such a baggage detector has not been widely used, so many police officers and security personnel had to take out the baggage and look at it, but recently, the baggage scanner has been widely used to easily identify the contents by projecting X-rays as described above. As it is spread, baggage retrieval is much easier and faster.

Therefore, in the past, the contents can be quickly searched using the baggage checker, and only when there is a suspicion about the contents due to the baggage checker, the police officer or security personnel take out the contents directly and perform a check / search by checking or the like. It is also contributing to strengthening the screening and screening network while preventing the baggage carriers from delaying passageways.

However, conventionally, the baggage importer who has placed a baggage on such a baggage screening machine often fails to arrest the criminal as he or she secretly escapes or sneaks on the spot when dangerous goods are detected, and disturbs such as denying the baggage. There were some difficulties, such as the difficulty of the investigator in obtaining evidence.

To this end, conventionally, a plurality of cameras installed in various parts of a building to detect criminals mixed in the baggage importer or persons who are likely to be blacklisted by terrorists, the military or the police (hereinafter referred to as "criminalists") are used. The inspection and search were conducted in the form that the management personnel and the policeman of the lifespan arranged in the camera operating room directly contrasted the face with the attention person, but this is also an unusual behavior because the face of the baggage carrier is not accurately identified. After this discovery, arrests are often made late, requiring more fundamental precautions.

In addition, since the number of personnel needed to be mobilized to inspect / search all the baggage importers directly by the police officers or security personnel, not only increases the expense of the inspection / search, but also requires a lot of time. There was a problem that the effective check / search is not done.

The present invention has been made to solve the above-mentioned problems. When the baggage carried by the baggage carriers is placed on a baggage detector, the baggage searcher and face recognition functions are integrated into one system. Simultaneously photographing the appearance of the baggage particle and the face image signal of the baggage particle and the searcher's face data stored in the face database to retrieve the person in advance, and if the dangerous goods are extracted in the baggage secondary of the photographed baggage particle The object of the present invention is to provide a retrieval system that combines baggage retrieval and face recognition functions that can store virtual users even by using images.

First, FIG. 2 is a block diagram showing the present invention search system, and the present invention system includes a control unit 1 for overall control of each part of the system, and an X-ray projected onto the baggage 300 to check its contents. A known baggage detector 2 and an X-ray generator 3 installed at one side of the baggage detector 2 to generate X-rays to the baggage 300 according to a control signal of the controller 1; When the X-rays are projected from the baggage 300, the X-rays unit 4 converts the image signal.

In addition, the camera for photographing the face and appearance of the baggage when the baggage tag particle 200 is placed on top of the baggage detector 2 when the baggage detector 300 is placed on the baggage detector 2 ( 5) and an image signal processor 6 for receiving the face image signal of the baggage particle 200 photographed from the camera 5 and converting the face image signal into a digital form, and from the image signal processor 6; The comparison search unit 8 which compares / searches the transmitted face image signal of the baggage importer 200 with the face data of the attention person previously stored in the face database 7 and reads out a match. When the face image signal of the baggage importer 200 is matched with one of the face data of a plurality of cautions stored in the face database 7, the face image signal is changed through the speaker 10 or the beacon 11 according to the control signal of the controller 1. Seen The alarm generating unit 9 for outputting a call and the face data of the attention person who coincides with the face image signal of the baggage importer 200 at the same time that the alarm generating unit is operated are output together with the identification information, or from the X player body unit 4 A monitor 12 which visually outputs the transmitted video signal so that the management agent 400 can read the contents of the baggage 300, and is connected to the control unit 1 so that an operator directly inputs a command to each system. The entire system consists of a key input unit 13 for controlling and managing the unit, and a power supply unit 14 for supplying power required for each unit in the system.

Here, the video signal processing unit 6 is preferably configured by employing a digital video recorder (DVR), which is widely used today, which is used by the DVR for a quick data matching process of the controller 1. This is because it is a suitable device.

The DVR is a next-generation video storage device that converts an analog video signal input through the camera 5 into a digital signal and compresses and records and reproduces the video according to a video compression method (MPEG). Unlike other recording tapes, long-term recording is possible, and it is easy to search and edit recorded video.

Moreover, the DVR can be easily installed on the PCI bus of the general PC to convert the general PC into the DVR, or can be additionally installed in various forms, such as being operated based on a separate motherboard that independently performs the functions of the PC. It is an excellent device to be adopted in the search system of the present invention because it is excellent.

Hereinafter, the operation method according to the configuration of the present invention search system as follows.

3 is a flow chart showing the operation process of the present invention search system, the baggage importer 200 is installed on top of the baggage detector 2 when the baggage 300 carried on the baggage detector 2 is placed. Photographing, by the camera 5, the appearance of the face of the luggage particle 200 and the luggage 300 (S100); A step in which the image signal processing unit 6 receives a face association signal of the baggage importer 200 photographed by the camera 5 and converts it to a digital form (S110); Comparing and searching the face image signal converted by the image signal processor 6 with face data of a plurality of subjects stored in the face database 7 and reading a match (S120); When the face image signal of the baggage importer 200 is matched with one of the subject's face data stored in the face database 7 by the comparison searching unit 8, the alarm generating unit 9 operates to operate the speaker 10. Alternatively, the alarm signal is output through the warning lamp 11 (S130).

In addition, at the same time with all the above steps, the X-ray generated from the X-ray generator 3 is projected to the luggage 300 when passing through the baggage detector 2 of the luggage 300 placed on the baggage semi-particle 200 (S140). Wow; When the X-ray projecting the baggage reaches the X player unit 4, the X player unit 4 converts it into an image signal (S150); The management agent 400 monitors the video signal transmitted from the X-athlete unit 4 visually on the monitor 12 to directly search for dangerous goods in the baggage 300 (S160); Are performed sequentially.

In addition, the comparison search unit 8 reads the match between the face image signal of the baggage importer 200 and the face data of the caregiver stored in the face database 7 in advance, and the picture of the matched caregiver on the monitor 12. By making the identification information and the output together, the management personnel 400 and the policeman to perform the inspection / search to easily identify the identity of the baggage importer 200.

Thereafter, the baggage 300 having the baggage particle 200 mounted on the baggage detector 2 generates an image signal at the X player body 4 as the X-rays generated by the X-ray generator 3 are projected. As the video signal is transmitted to the control unit 1, the management personnel 400 seated in front of the monitor 12 visually checks the contents and extracts the dangerous goods.

Meanwhile, the face recognition technology (FRT) used in the above will be described in detail.

The face recognition technology is a technology that has been recently applied in various fields due to the rapid advancement of technology, and the process of matching and reading a critical person among the numerous face data stored in the face database 7 is gradually progressed due to the development of high performance equipment and a search engine. It can be done in just a few seconds.

Therefore, the present invention retrieval system is the baggage semiparticle 200 taken by the camera 5 while the baggage semiparticle 200 puts its baggage 300 on the baggage retrieval machine 2 as the face recognition technology is applied. The facial image signal of the subject is matched with the subject's face data stored in the face database 7, so that the subject's facial image signal can be read out in a few seconds.

In general, the time required for such a matching process may vary depending on the processing capability of the controller 1, but in general, the time will be further delayed depending on the number of face data of the attention person input to the face database 7. At this time, by adjusting the installation angle of the camera (5) or by using a human body detection sensor should be adjusted to capture the baggage particle (200) from the far distance in front of the baggage detector (2).

Therefore, even if the present invention search system is installed in a large number of floating personnel such as airports, conference halls, stadiums, police stations, public offices, etc., a large number of baggage importers 200 can be promptly inspected / searched and the camera 5 The face image signal of the baggage importer 200 photographed by) is additionally stored in the face database 7 so as to prevent a criminal act that may occur later.

In addition, not only the single management personnel 400 can control and manage all the operations of the entire search system through the key input unit 13, but also the baggage importer 200 on the monitor 12 automatically when the attention is found. Photographs and identity information of the attention person in accordance with the pop-up (Pop up) by a number of management personnel 400 as conventionally look at the image taken through the camera (5) and the necessity of contrast between the baggage importer 200 and the attention person There will be no.

Furthermore, once the face is photographed, the baggage half particle 200 automatically stores the face image signal of the baggage half particle 200 in the face database 7 so that the landscape database or the like does not need to directly identify the face when searching. ), So that more efficient search operation is possible through face recognition, which can drastically reduce the number of management personnel 400 according to the landscape, safety personnel, and system management that have been put into conventional inspection / search operations.

Therefore, in the conventional inspection / retrieval work, the general public, not the worker has to be uncomfortable to identify each time when entering, but when using the system of the present invention not only can identify the identity of the baggage importer 200 within seconds, but also once identity Since the baggage importer 200 is additionally stored on the face database 7 after being identified, the task of identifying the identity is very simple, and thus it is possible to perform an effective access control task.

In addition, when the baggage importer 200 and the baggage 300 are photographed together by the camera 5 in the face recognition process, the dangerous goods are found in the baggage 300 after being stored in a predetermined storage medium. Since it can be submitted as solid evidence during the investigation process, it not only raises awareness about those who conceal their crimes but also has the advantage of helping to prevent crimes.

Meanwhile, another operation method of the system according to the face recognition in the present invention search system stores only the face data of the baggage importer 200 allowed to enter and exit the face database 7, and thereafter, the baggage importer 200 enters and exits. The comparison search unit 8 compares / searches the face image signal of the baggage importer 200 which is allowed to enter and reads the face image signal of the face image signal, and at this time, the face image signal of the baggage importer 200 enters and exits. If any one of the face data of the allowed baggage importer 200 does not match, the alarm generator 9 may be configured to output an alarm signal through the speaker 10 or the beacon 11.

This is a form suitable for use as a security system, such as a laboratory in which the number of baggage importers 200 expected to enter and exit is limited to a small number of people, and reduces the load of performing the matching process of the face database 7 so that a faster searching operation is possible. This has the advantage of being made.

In addition, the present invention search system is not only available for the above-mentioned baggage retrieval, but also applicable to a large-scale freight retrieval system or a precious metal storage room such as a bank, the scope of application will be very diverse. Based on the technical gist of the specification, it is stated that various modifications and additions of components are possible.

The search system that combines the baggage screening and face recognition functions of the present invention extracts the suspected criminals through images taken primarily with cameras for a large number of baggage importers, and whether they carry dangerous goods that are carried in the baggage. As a result, a large number of baggage importers can perform a quick and accurate retrieval operation so as not to delay access in the aisle.

In addition, the baggage importer once a face is photographed is stored in the face database by adding the face image signal of the baggage importer, so that the subsequent search operation is facilitated. It is possible to reduce the number of management personnel according to the minimum number of personnel, so that it is possible to reinforce the expenses of other security needs, and it is very effective because it can greatly reduce the work time and expense expenditure required for the inspection / search.
