Description

{A method to prevent unauthorized crossing of a crosswalk using a camera module}

The present invention relates to a method of preventing trespassing in a crosswalk using a camera module, and more particularly, it collects and recognizes face information of trespassers using a camera module and converts it into a database so that habitual violators can be discovered, violation facts It is related to a system for preventing trespassing at crosswalks by sharing with LED warning lights, speakers, and screen display units, as well as with those around them, so that violators are alerted to those around them.

Over the past five years, 6 out of 10 pedestrians in Seoul have been killed by jaywalking. Although the number of jaywalking accidents has decreased from 2014 to the present, it has consistently accounted for a high accident rate, and the damage rate is 10 times higher than that of other accidents. In 2018, there were 8,961 jaywalking accidents, about 1,000 fewer than in 2017, the previous year. However, jaywalking at non-crosswalks has decreased, and jaywalking within crosswalks is still high.

Recently, several products to prevent jaywalking have been developed to reduce such traffic accidents, but such products are products such as a center lane separator that prevents jaywalking in places where there is no crosswalk. There are very few products designed to reduce jaywalking in crosswalks.

When people crossed the road at the crosswalk, the signal changed, but there were cases where an accident occurred by ignoring the crossing, and the number of cases where people crossed without seeing the signal because they bowed their heads and looked at their cell phones has increased in recent years. Therefore, if the people next to you move without seeing the signal, there are many cases of accidents while crossing when moving together.

As an example, there is a safety-bar installed to prevent crossing the crosswalk in front of the existing elementary school. This safety-bar simply makes the bar move when the traffic lights are red and green, and it did not play a big role in preventing accidents such as children turning the safety-bar.

In addition, the 'high-frequency sensor module for trespassing prevention equipped with an alarm' is known through the Republic of Korea Utility Model Registration No. 20-0456876.

The prior art is a case mounted on the upper side of the traffic light post of the crossing orthogonal to the crosswalk in order to prevent trespassing; a sensor unit mounted on the case to detect a moving object by emitting a high-frequency beam to the crossing in a direction perpendicular to the crosswalk; and an alarm unit that outputs a warning signal with sound or light when the object detected by the sensor unit is out of the range of the emission area of the high-frequency beam projected on the crossing when the traffic light is a red signal and moves toward the crosswalk.

The prior art is a device that generates an alarm by operating a sensor when a person jaywalks, but this works very limitedly only within the laser range, and there is a problem that it does not substantially affect people other than the function to give an alert. .

2 is a flowchart illustrating a method for preventing unauthorized crossing of a crosswalk using a camera module according to the present invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram illustrating a system for preventing trespassing of a crosswalk using a camera module according to the present invention, and the present invention as shown in the same drawing is largely a main body 110, a camera module 120, and an LED warning light 130. , a speaker 140 , a screen display unit 150 , and a central processing unit 160 .

First, the main body 110 will be described. The body 110 is a structure installed on one side of the crosswalk, and has an external shape such as a cabinet shape or a police model.

A camera module 120 is installed on the upper portion of the body 110, and the camera module 120 is installed to photograph the face of a trespasser, and the installation height of the camera module 120 is adjusted to the average face height of pedestrians. It is preferable to install

At this time, the camera module 120 includes an infrared photographing mode capable of night photographing.

The camera module 120 tracks and shoots the face of the pedestrian according to the automatic focusing function, captures the face of the offender based on when he enters more than a set distance from the sidewalk to the roadway, and centrally processes the face information of the offender taken at this time. to be stored in the device 160 .

The camera module 120 may be configured as a camera module using a Raspberry Pi.

Here, the Raspberry Pi is a credit card-sized ultra-small/ultra-low-cost PC developed by the Raspberry Pi Foundation in the UK for the purpose of a project for basic computer science education in schools. The concept was formed in 2006 and the foundation It was created and first released in 2012, and sold 1 million units in early January 2013.

The characteristic of Raspberry Pi is that unlike Arduino, it can become a PC by simply connecting a keyboard, mouse, and monitor. In other words, it is a product that emphasizes that it is similar to a general desktop. It is based on the Linux OS and provides a customized environment for novice programmers by providing detailed settings.

The camera module 120 using the Raspberry Pi is connected to a traffic light by wire to receive a traffic light signal.

In addition, an LED warning light 130 is installed on one side of the camera module 120, and the LED warning light 130 installs a green light and a red light together, and sends a blinking signal at regular intervals (2 seconds, 5 seconds, etc.) have.

The LED warning light 130 turns on when a person (jaywalker) is recognized within the camera range, and at the same time causes the camera module 120 to start face recognition.

In addition, a speaker 140 is installed on one side of the camera module 120 . The speaker 140 broadcasts a warning sound to trespassers so that they can pay attention to signal violations so that they can focus their efforts on self-cleaning.

In addition, the screen display unit 150 is installed on the main body 110 . The screen display unit 150 displays a message that the enforcement camera is being filmed to notify people passing the crosswalk, while displaying the face of the trespasser on the screen so that the violators themselves can realize their wrong behavior and wake up. open up

In addition, the central processing unit 160 is installed inside the main body 110 . The central processing unit 160 generates the face information of the trespasser received from the camera module 120 and stores it in the database, and based on the face information, determines the habitual offender and alerts or notifies the police of the violation. .

The jaywalking prevention system of the present invention as described above is installed on the right side based on the crosswalk, and the traffic light is located on the left side. Pedestrian face information is used by directly photographing a person's face on the crosswalk.

2 is a flowchart illustrating a method for preventing unauthorized crossing of a crosswalk using a camera module according to the present invention.

Referring to FIG. 2 , the present invention performs a first step (s10) of operating a face recognition camera when a red light is turned on at a traffic light.

When the green light comes on, the crosswalk is crossed. When the red light comes on, when the crossing is recognized, a signal is sent to the central processing unit 160 to operate the camera.

Then, when a face is detected by the camera, it is regarded as trespassing and a second step (s20) of turning on an LED warning light around the camera is performed.

For example, when a green light is on at a crosswalk, when a person is recognized by the camera, "Blue Signal" is displayed on the screen to indicate the green light, and when a red light is on, when a person is recognized by the camera, the recognized face information is displayed on the screen display. , the LED warning light is turned on to warn.

Then, the third step (s30) of detecting the face information of the trespasser and searching the database is performed.

Then, as a result of the search, a fourth step (s40) of determining whether the number of jaywalking exceeds a reference number is performed.

And, if the fact of trespassing is more than the standard number of times, the fifth step (s50) of notifying the violation by accessing the computer network of the police station is performed.

At this time, if the fact of trespassing is less than the standard number of times, step 5-1 of broadcasting a warning sound is performed.

Steps 5 and 5-1 are cases in which jaywalking is violated more than once, and the previously registered face information is detected from the database and an alarm sound is sounded together with an LED warning light.

In this case, the screen display unit may display the number of violations along with the face information of the trespasser and the subject of the penalty to be notified.

The camera module 120 of the present invention uses a face recognition technique using a Raspberry Pi. First, using the haarcascade program, write the coding that the Raspberry Pi camera module recognizes the face. To this end, 50 sets of frontal faces of a person are set, taken, and stored in an image file.

After that, the stored image file is trained, and a command is input to recognize a face that has entered when the red light is on using the trained image database.

When the green light is on at the crosswalk, when a person is recognized by the camera, "Blue Signal" is displayed on the screen to indicate the green light. If a person is recognized by the camera while the red light is on, it is judged as a crossing signal violation, the violator's face information is displayed on the screen display, and the LED warning light blinks.

In addition, a warning message and a warning sound may be broadcast through a speaker together with the LED warning light.

As described above, the present invention collects and recognizes face information of trespassers using a camera module and converts it into a database so that habitual offenders can be detected, and violations are reported to the person as well as to the surroundings through LED warning lights, speakers, and screen display units. By sharing with people, violators can alert those around them to voluntarily change their erroneous road traffic awareness, while also enabling facial recognition to track and impose fines on jaywalkers. It is possible to dramatically improve social problems caused by trespassing, prevent trespassing by raising awareness about trespassing, and also save many lives by reducing traffic accidents.

As described above, the present invention is not limited to the specific preferred embodiments described above, and any person skilled in the art to which the invention pertains may make various modifications without departing from the gist of the present invention as claimed in the claims. It is of course possible to implement, and such modifications are intended to be within the scope of the claims.
