Field of the Invention The present invention relates to an endless crossing detection system and, more particularly, to an endless crossing detection system which provides information to recognize the information of a crossing object that is endlessly crossing using vehicle- .

Today, our society is making rapid progress in road traffic, and cars are popular transportation means that traffic accidents are causing hundreds of thousands of casualties and property damage every year.

Traffic accidents are changing rapidly due to frequent mobility of the population due to the concentration of the population in the city and the increase of the economically active population, and the rapid increase of the leisure population due to the five - day work week.

Although the benefits of automobiles that are indispensable in modern life are beneficial to us, most of the roads shared by drivers and transit objects are occupied by automobiles, so that the right of pedestrians who can be regarded as basic human rights is limited This has been a devastating result of a traffic accident.

According to statistics, transit traffic accidents are increasing year by year, and the majority of them are accidents while crossing without permission, and crossing accidents among crossing objects occur most frequently at night time (18:00 ~ 24:00). Crossing Object Most of the traffic accidents occur when crossing a road or crossing a road, so the coexistence of a vehicle and a crossing object in a specific road section is very serious. A detailed examination of the types of traffic accidents involving crossing objects is often done in the care of the driver, in the carelessness of the driver, and in the self-centered driving behavior of the driver. The crossing object may be traversed by unauthorized crossing or careless crossing of roads without crossing facilities The accident is caused by misrepresentation of pedestrian culture.

Especially, in the case of rural areas, the elderly are increasing due to aging. The elderly people are less motivated than the younger generation, so it is difficult to evacuate quickly in dangerous situations. In the nighttime, they cross the country roads and roads without permission. Is frequently occurring.

However, most of the conventional anti-crossing fences are applied to roads with two-lane or more one-way roads. Also, since the posts are installed on the center line of the roads, problems such as labor and cost are incurred. Therefore, if a crossing object is unreasonably crossed over an unauthorized crossing fence, it is possible to cause a greater accident, and the driver can not recognize any kind of unauthorized crossing of the crossing object, .

FIG. 2 is a block diagram showing a specific nose configuration of the endless traverse detection system according to the present invention shown in FIG. 1. FIG.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an endless crossing detection system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an endless crossing detection system according to the present invention. 1 and 2, the endless traverse sensing system according to the present invention includes a walking detection unit 100; And a traveling detection unit (200).

The gait detecting unit 100 includes a sensing unit 110, a first wireless communication unit 130, and a walking alert unit 150.

The sensing unit 110 is installed along a road to sense a transverse object crossing the road and outputs a transverse signal. As shown in the figure, the sensing unit 110 is installed in a support 110a such as a street lamp or a telephone pole have.

The sensing unit 110 includes an illuminance sensor 111 for measuring illuminance and transmitting illuminance information, a first camera 112 operating when the illuminance value measured by the illuminance sensor 111 is equal to or greater than a preset reference illuminance value, A second camera 113 that operates when the illuminance value measured by the illuminance sensor 111 is less than the reference illuminance value and acquires a thermal image; and a second camera 113 that operates when the first camera 112 and the second camera 113 An image analyzing unit 114 for analyzing the acquired image and determining whether the traversing object is traversed and outputting a traverse signal, and an image analyzing unit 114 for analyzing the acquired image, (115) for switching the operation of the switch (113).

The first camera 112 generally uses a general camera used for photographing an image and the second camera 113 uses an infrared camera that senses and imaged a radiation of an infrared band emitted from a heat source . It is preferable that the first camera 112 and the second camera 113 have a relatively wide photographing area so as to photograph the area around the road and the road.

The image analyzing unit 114 analyzes the reference image photographed in advance through the first camera 112 and the second camera 113 and the reference image photographed periodically at the first camera 112 and the second camera 113 And compares the photographed images (comparison target images) to judge whether or not the traversing target is traversed.

The image analyzer 114 stores both a first reference image by the first camera 112 and a second reference image by the second camera 113. The reference image is compared with the first reference image according to illumination information, The target image is compared or the second reference image and the comparison target image are selectively compared.

The image analyzing unit 114 stores the comparison object image photographed by the first camera 112 in a database and displays the normal image (first reference image) without the traversing object on the road and the normal image The difference between the captured image and the comparison target image is compared, and if the difference exceeds the set range, it is determined that the traversing target is traversing and then a traverse signal is output. The image analyzing unit 114 detects a change in a pixel in the photographed image, and recognizes the change in the pixel as an endless crossing when the change in the pixel is greater than a predetermined value.

The image analyzing unit 114 preferably sets directionality with respect to a change in image pixels. In other words, it is determined that the change of the pixel in the direction from the sidewalk to the road crossing is endless, but the progress of the road so that the vehicle does not judge the endless crossing both when moving along the road or when the crossing object moves along the sidewalk Pixel changes in the direction parallel to the direction are not recognized as endless traversal.

The image analyzing unit 114 stores the image photographed by the second camera 113 in a database similar to the traverse determination through the first camera 112, The difference between the reference image and the image photographed by the second camera 113 is compared. If the difference exceeds the set range, it is determined that the traversing target is traversing and then the traversing signal is output. The image analyzing unit 114 detects the change of the pixel in the photographed image, and recognizes the change of the pixel as the endless crossing when the change of the pixel is not less than a predetermined value.

For example, in a small animal such as a mouse at the same distance, the sensing area photographed by the second camera 113 is small, and in the case of a person, the photographed sensing area is large. Therefore, The situation can be recognized. It is preferable that the image analyzing unit 114 is set to have directionality with respect to the change of the pixels as described above.

The switching unit 115 may be configured to allow the first camera 112 to acquire an image through the first camera 112 during the day and the second camera 113 to acquire an image through the second camera 113 during the night, And selectively drives the camera 113.

The first wireless communication unit 130 transmits the crossing signal output from the sensing unit 110 and the location information of the location where the sensing unit 110 is located. The first wireless communication unit 130 stores location information of the sensing unit 110 or the sensing unit 110. When the sensing unit 110 outputs a sensing signal to the sensing unit 110, And is transmitted by radio. It is preferable that the first wireless communication unit 130 can reach a signal from a point where the sensing unit 110 or the support 110a is installed to a point located within a predetermined distance.

The walking warning unit 150 is installed adjacent to the sensing unit 110 and outputs a warning signal to the transit target through light or sound when the sensing unit 110 outputs a traverse signal. A buzzer 153 for outputting a warning sound, and a controller 155 for controlling the operation of the illumination lamp 151 and the buzzer 153.

The illumination light 151 may be omitted when the sensing unit 110 is installed in the streetlight. In this case, the controller 155 preferably controls the operation of the lamp installed in the streetlight. Alternatively, when the sensing unit 110 is installed on a telephone pole, it is preferable to separately provide the sensing unit 110 with brightness sufficient to recognize the light of the crossing target object.

The controller 155 controls the buzzer 153 to operate when the illuminance value measured by the illuminance sensor 111 is equal to or greater than the reference illuminance value, And controls the illumination lamp 151 to blink when the reference illumination value is less than the reference illumination value. For example, when the illuminance value measured by the illuminance sensor 111 is greater than the reference illuminance value corresponding to the illuminance corresponding to a cloudy day or a twilight with a small solar radiation amount, the controller 155 may turn on the illuminating lamp 151, It is possible to control the operation of the buzzer 153 without controlling the illumination lamp 151 and to control the illumination lamp 151 to turn on or blink when the measured illumination value is smaller than the reference illumination value So that the traversing object can recognize it. Further, the controller 155 can control both the illumination lamp 151 and the buzzer 153 to operate regardless of the illumination value.

The controller 155 controls the illumination lamp 151 and the buzzer 153 to operate only when a crossing signal is output from the sensing unit 110. Alternatively, The operation of the illumination lamp 151 and the buzzer 153 can be controlled by referring to a separate vehicle proximity signal received through the first wireless communication unit 130. [ In this case, it is preferable that the first wireless communication unit 130 and the second wireless communication unit 210 provided in the travel sensing unit 200, which will be described later, are able to exchange wireless signals with each other.

The vehicle proximity signal received by the first wireless communication unit 130 is received by the second wireless communication unit 210 installed in the vehicle within a predetermined distance from the sensing unit 110 by receiving a crossing signal transmitted from the first wireless communication unit 130 The wireless signal transmitted to the first wireless communication unit 130 again indicates that the vehicle is running close to the sensing unit 110 to which the transverse signal is transmitted and that the vehicle is approaching the sensing unit 110 It is a signal. That is, the vehicle proximity signal may be a signal for determining whether to operate the illumination lamp 151 or the buzzer 153 for giving a warning to a traversing object traversing the road.

The first wireless communication unit 130 can not receive signals transmitted from the second wireless communication unit 210 of the vehicle located outside the predetermined distance from the sensing unit 110, When the signal is not received, the controller 155 does not need to control the operation of the illumination lamp 151 and the buzzer 153.

The travel sensing unit 200 includes a second wireless communication unit 210, a GPS terminal unit 230, and a driving warning unit 250.

The second wireless communication unit 210 is installed in a vehicle traveling along the road and receives a transit signal and position information transmitted from the first wireless communication unit 130 and is capable of communicating with the first communication unit . The second wireless communication unit 210 may be configured to enable bidirectional communication with the first wireless communication unit 130 as described above. In this case, when a traverse signal is transmitted to the second wireless communication unit 210, the vehicle proximity signal can be transmitted to the first wireless communication unit 130 wirelessly.

The GPS terminal unit 230 receives the position information of the vehicle, displays the traveling path of the vehicle, and transmits a crossing signal based on the position information received from the second wireless communication unit 210 to the sensing unit 110, A display 232, and a distance calculating unit 233, as shown in FIG. The GPS terminal unit 230 may apply conventional navigation.

The GPS receiver 231 acquires current position information of the vehicle, and can acquire not only current position information of the vehicle but also surrounding map information and vehicle speed information. The display 232 displays not only the position information, the map information, and the speed information of the vehicle received by the GPS receiver 231 but also the position of the sensing unit 110 to which the traveling path and the transverse signal of the vehicle are transmitted have. The distance calculating unit 233 calculates the distance between the position of the sensing unit 110 and the position of the current vehicle which transmitted the crossing signal and the distance information calculated by the distance calculating unit 233 is transmitted to the display 232 ).

The running warning unit 250 outputs a warning signal to the driver when the position of the sensing unit 110 displayed on the GPS satellite terminal unit 230 is located in front of the traveling path of the vehicle, A light emitting unit 251 that emits light and a voice output unit 253 that outputs a warning voice to the driver. The running warning unit 250 is set such that the light emitting unit 251 and the audio output unit 253 do not operate when the position where the crossing signal is transmitted is behind the vehicle in which the traveling vehicle has already passed.

The travel detecting unit 200 further includes a speed limiting unit 270 that limits the speed of the vehicle to prevent the vehicle from being accelerated above a predetermined reference speed when the distance calculated by the distance calculating unit 233 is within a predetermined distance, And a blinking control unit 290 for controlling the emergency light provided in the vehicle to blink.

The speed limiter 270 limits the speed of the vehicle by preventing the speed limiter 270 from accelerating beyond a predetermined reference speed even if the driver accelerates by being linked to the control system of the vehicle so as to prevent a collision with the traversing object crossing the road, Can be prevented.

The blinking control unit 290 controls the blinking control unit 290 so that the blinking control unit 290 can control the blinking object to walk along the sidewalk around the sensing unit 110 or the crossing object traversing the road around the sensing unit 110, The emergency light installed in the vehicle is controlled to be periodically turned on so as to recognize that the vehicle is approaching.

When the vehicle approaches the vicinity of the sensing unit 110 through the speed limit unit 270, the speed of the vehicle is limited to a predetermined speed or lower, thereby improving the accident avoidance rate due to low-speed operation. It is possible to make the traversing target traversing the road around the sensing unit 110 to have a sense of warning, thereby preventing an accident from occurring.

In the meantime, the endless crossing detection system according to the present invention is characterized in that, when a crossing signal is output from the image analyzing unit at night, a transverse crossing that determines whether a crossing object traversing the road around the sensing unit 110 is a person or an animal An object determining unit 190 is further provided in the gait detecting unit 100. [

The gait detecting unit 100 may detect whether the traversing target is a person or an animal through the traversing object judging unit 190 at a time when the traverse signal is output from the image analyzing unit 114, 112 are operated to acquire an image of the surroundings of the sensing unit 110.

When the traversing target crosses the road at night, the gait detecting unit 100 outputs a traverse signal from the image analyzing unit 114. At this time, the light of the walking warning unit blinks and illuminates the traversing target . In addition, the first camera 112 is adapted to acquire an image of the surroundings of the sensing unit 110. The image obtained by the first camera 112 is stored in a separate memory and then analyzed by the traverse object determination unit 190.

The traverse object determining unit 190 determines that a human image exists in the image obtained by the first camera 112. If the image is similar to a wild animal such as an elk or wild boar, If it exists, it is judged to be an animal.

On the other hand, the crossing object discrimination unit 190 can visualize the light reflected by the eyes of the wild animal through the first camera to acquire an image and analyze the acquired image to determine whether the crossing object is a human or an animal have. That is, if the two images, which are brighter than the surrounding area, are recognized in the image acquired by the first camera 112, the traverse object determination unit 190 can determine the traversing object as an animal. In other words, in the case of a person, the light is not reflected from the eye, so it is easy to discriminate.

The gait detecting unit 100 is configured to transmit a human body detection signal through the first wireless communication unit 130 when it is determined that the transverse object is a person in the transverse object discriminating unit 190, An animal detection signal is transmitted through the first wireless communication unit 130 when it is determined that the animal is an animal.
