Description

[0001] The present invention relates to a school zone security device using a vehicle and a pedestrian detection device,

The present invention relates to a school zone security device using a vehicle and a pedestrian detection device. More particularly, the present invention relates to a school zone security device that uses a vehicle and a pedestrian detection device to photograph an object only when the object enters a school- The facial feature information is detected from the image and compared with the already registered criminal facial feature information. When the degree of similarity of the two data is equal to or greater than a predetermined set value (TH: Threshold) By instantly spreading to pedestrians, it is possible to efficiently prevent crime in the school zone in advance and reduce the amount of computation required for facial recognition, thereby reducing the number of crime victims in real time. The present invention relates to a security device.

As the crimes of various kinds, especially children, are increasing rapidly, there are various studies on the crime prevention system for effectively preventing the crime in the school zone.

The most important purpose of this school zone crime prevention system is to prevent crime in advance by blocking crime factors before crime occurs, and to promptly and promptly process crime when crime occurs.

Conventional school zone crime prevention system detects a criminal's personal image by analyzing images obtained by taking a camera when a crime occurs or after a crime occurs by installing a plurality of CCTV cameras in a school zone, Although the evidence on escape routes is collected, this method is not used to prevent crime in advance, but after the occurrence of the crime, it is carried out after the report is handled to the police officers and administrators. Since the photographed images are used for the purpose of collecting evidence, And has a disadvantage that the prevention efficiency is low.

Also, in the conventional security system, it is difficult to recognize the face of the criminal because the image quality of the known CCTV camera is deteriorated. Even if the criminal's face is recognized, in order to detect the image of the criminal based on the recognized face, A consuming problem arises.

Accordingly, various studies are being conducted to reduce the crime rate by using the photographed images as a basis for judging whether a crime occurs, which is not merely for collecting evidence.

1 is a structural diagram showing a ubiquitous surveillance system using a face recognition DVR described in the prior art of Korean Patent No. 10-1170014 (Ubiquitous surveillance system using face recognition DVR and its method).

1, the conventional surveillance system 100 of the present invention includes at least one camera 101 for capturing an image of a subject, a face detection unit 110 for detecting a face region of the subject from the image captured by the camera 101, Extracts a facial feature code (FC) and a facial image (FI), transmits them to a face recognition (FR) server through a network, receives authenticated and retransmitted registrant data from a face recognition (FR) At least one face recognition DVR (Digital Video Recorder) 103, a face characteristic code FC received from the face recognition DVR 103 and a face image FI are compared with the registered registrant database, A facial recognition (FR) server 105 for retransmitting the registrant data to the face recognition DVR 103 in the case of a preset reference value or more, A display unit 107 for displaying a face image, and an external face recognition (FR) module 109.

The conventional surveillance system 100 configured as described above is configured such that the face recognition DVR 103 receives a face feature code FC and a face image FI And transmits the extracted data to the face recognition server 105. The face recognition server 105 compares the extracted facial characteristic code and the facial image with the registered database unit based on the received facial characteristic code and the facial image, By transmitting the data to the face recognition DVR 103, it is possible not only to detect the presence of a person having a large risk factor such as a criminal or a terrorist (hereinafter referred to as a criminal), but also to cope with the crime of a crime victim quickly.

In this case, the face recognition algorithm generally has an advantage of utilizing the photographed image for various purposes by recognizing the face of the object to be photographed from the photographed image, but since the operation is very complicated, time is delayed However, it has disadvantages in that it is expensive and expensive.

Accordingly, when the conventional surveillance system 100 is installed in an area with a large floating population, the total amount of calculation of the face recognition objects exceeds the maximum calculation amount of the face recognition DVR 103 as the number of objects to be subjected to face recognition increases, The real-time monitoring function such as that the face recognition is not performed in real time or is performed later is lost even if the person to be crime is photographed.

In order to overcome such a problem, it is necessary to increase the number of face recognition DVRs 103 in proportion to the total amount of calculation of face recognition objects. However, if the number of installed face recognition DVRs 103 is increased, .

In particular, when the conventional surveillance system 100 is installed in a school zone in which a floating population such as a child, a guardian, and other pedestrians is concentrated, the real-time monitoring efficiency is deteriorated due to the reasons described above. At this time, the school zone generally has a characteristic that the concentration of children is concentrated compared to that of an adult. However, the conventional monitoring system 100 does not have a means of determining whether the sensed object is an adult or a child, By performing the face recognition operation to the children whose probability of jersey is relatively low, the time for performing the useless operation is increased. Accordingly, the face recognition is performed for the adult having a relatively higher probability of preventing the crime than the child I can not.

Considering the environmental characteristics of school zone, which has more children 's floating population than adults, it is urgent to study crime prevention system which can prevent crime based on face recognition.
