Description

{Apparatus for safety crosswalk}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedestrian safety device, and more particularly, to a pedestrian safety device that enables a vehicle driver to detect a person crossing a pedestrian crossing in advance before securing a view.

Conventional intersections and crosswalks are equipped with pedestrian traffic lights and vehicle traffic lights, so if a driver is not able to quickly recognize a vehicle traffic light hanging in the air above about 10 meters above the ground, Ignoring them and passing through crosswalks and intersections posed a serious threat to the safety of drivers and pedestrians.

1, the driver of the vehicle V can make a right turn at the outermost lane regardless of the signal in the forward direction. However, the crosswalk S located on the road on which the vehicle V makes a right turn before entering the right turn road is difficult to secure in the driver's view.

It is also difficult to find pedestrians crossing without permission when the pedestrian crosses without permission because the road is not secured when the pedestrian crosses on the right.

In order to compensate for this, a vehicle traffic light at an intersection can be installed at the opposite side of the intersection from the rear of the intersection to the vehicle stop line ahead of the intersection. However, there is a problem in that the cost is high or the driver does not coincide with the direction of the gaze.

In addition, a convex mirror can be installed at the intersection, but it has low utility in that a parked vehicle is covered with a convex mirror or is not visible at night.

In addition, a Wyirus system that detects pedestrians with Wi-Fi can be used, but pedestrians must have electronic products that operate on Wi-Fi.

Blind Spot Information System (BLIS) system, which is a radar blind spot information system, can be used. However, it is possible to detect people who are over 80cm in height or who are carrying bulky luggage.

The image signal processor performs a function of generating screen data for displaying a video signal output from the CCD image sensor of the camera. The image signal processor processes the image signal outputted from the CCD image sensor of the camera frame by frame and outputs the frame image data as a video image according to the characteristics and size of the display screen. The image signal processor includes an image codec, compresses the frame image data displayed on the display screen in a predetermined manner, or restores the compressed frame image data into original frame image data. The image codec may be a JPEG codec, an MPEG4 codec, a Wavelet codec, or the like.

The image signal processor extracts an object shape from a video image and outputs a detection signal when the extracted object shape is not a vehicle shape. An outline of objects in a video image is extracted to detect a feature point, and an object shape can be extracted from a feature point in comparison with a previously registered feature point DB. When the extracted object shape is a human shape, a dog shape, a cat shape, etc., it outputs a detection signal to the control center server 200.

Meanwhile, the detection sensor 130 may be implemented as an infrared sensor capable of detecting a human or an animal by detecting a wavelength of infrared rays emitted from a human body or an animal. When a human or animal is detected through an infrared sensor, Output. Since the infrared rays emitted from a human body or an animal have a wavelength of about 10 mu m, an infrared sensor can detect a person or an animal by detecting infrared rays of such a wavelength.

The sensor 100 is provided at both ends of the transverse sidewalk S and is provided at both ends of the transverse sidewalk S at a short distance as shown in Fig. 4 to detect whether there is an object crossing the transverse sidewalk S Lt; / RTI > 4, the first sensor 100a and the second sensor 100b are positioned at both ends of the first crosswalk S1 and the third sensor 100c is positioned at both ends of the third crosswalk S3. And the fourth sensor 100d may be located. Although not shown, the detectors 100 may be positioned at both ends of the second crosswalk S2 and at both ends of the fourth crosswalk S4.

In the following description, the first sensor 100a and the second sensor 100b provided at both ends of the first crosswalk S1 will be described as an example, but the following description will be applicable to the other sensors 100 as well.

The first sensor 100a is provided at one end of the first transverse sidewalk S1 and includes a first sensing sensor for sensing an object traversing the first transverse sidewalk S1 and outputting a first sensing signal, 1 alarm.

The control center server 200 may include a third sensor 100c and a fourth sensor 100d in addition to the second sensor 100b when the first sensing signal is received. Any one of the detectors 100 may be additionally selected and the alarm lamp 120 of the selected detector 100 may be blinked.

For example, when the first sensor 100a installed at one end of the first crosswalk S1 senses the crossing of a person, the first sensor 100a transmits a first sensing signal to the control center server 200 send. Upon receiving the first sensing signal, the control center server 200 transmits a command message to the second sensor 100b installed at the other end of the first crosswalk S1 to cause the alarm to blink. In addition, the third sensor 100c installed at the other end of the third crosswalk S3 can transmit a command message to cause an alarm to be blinked. The second sensor 100b and the third sensor 100c having received the alarm flicker command message can flicker a second alarm light, which is its own lamp, to notify that a person is crossing through the first crosswalk S1.

Therefore, the vehicle which is going to make a right turn and enters the first crosswalk (S1), the alarm flashing of the second sensor (100b) at the other end of the crosswalk (S) and the alarm flashing of the third sensor It is possible to recognize that a person is crossing the first crosswalk S1 that is going to make a right turn and to make a safe operation.
