Description

Collision warning device between car and pedestrian}

The present invention relates to a collision warning device between a vehicle and a pedestrian, and more particularly, when the vehicle enters into a child protection area and is driven, a collision between a driving vehicle and a pedestrian suddenly jumping into the road is predicted, causing a collision to the driver It relates to a collision warning device between a vehicle and a pedestrian that can prevent an accident by giving a warning.

Recently, there have been frequent traffic accidents between a car driving in a child protection zone and a child crossing the road. In such traffic accidents, drivers who are driving should pay more attention to their driving for the protection of children when driving within the child protection zone, but they violate the traffic rules, such as speeding or violating traffic signals in the child protection zone without such safety driving awareness. As a result, collisions with children occur frequently.

Children still lack the ability to accurately recognize cars and traffic situations because their attention and situational judgment skills are weak. Close attention is required.

On the other hand, even if the driver is not speeding or breaking a signal within the child protection zone, if a child runs immediately as soon as the green light turns on when crossing the crosswalk, or if a child suddenly jumps between parked and parked vehicles. If it is not discovered, it is difficult to completely prevent traffic accidents.

As such accidents are repeated recently, traffic accidents among children are occurring frequently, and countermeasures or preventive devices that can prevent accidents in advance, traffic safety education, and safety awareness are urgently needed.

The present invention has been devised to solve the above-mentioned problems of the prior art, and when a driving car enters a child protection area, it recognizes a pedestrian (child) crossing the road with a car and predicts a collision to provide a collision warning to the driver The goal is to provide technology that can prevent traffic accidents in advance through notification.

As a means for solving the above technical problem,

In the present invention, an image is inputted through a location determining unit 110 that determines that the vehicle has entered the child protection zone and an image input unit 120 that recognizes a road and a pedestrian (child) in front of the vehicle. As a result, there is an image processing unit 130 that recognizes the location of pedestrians (children) and the boundary of the road, and a data recording unit 140 that stores data obtained from the image processing unit. The collision prediction unit 150 for predicting and the warning processing unit 160 for notifying a warning warns the driver of a collision between the vehicle and the pedestrian (children) in advance.

By using the present invention, it is possible to prevent a collision accident with a pedestrian (child) suddenly jumping out of a driver while driving in a child protection area. It has the advantage of being able to prevent a collision with a pedestrian in advance by notifying a collision prediction warning.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art can easily carry out the present invention. However, the present invention may be embodied in several different forms, and is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted.

In addition, when a part "includes" or "includes" a certain component, this means that other components may be further included, rather than excluding other components, unless otherwise stated.

The present invention provides a positioning unit 110 that determines the current location of the vehicle through the GPS location information of the driving vehicle, and when it is determined that the driving vehicle enters the child protection zone through the positioning unit, pedestrians and roads in front The image input unit 120 for recognizing , the image processing unit 130 for calculating the position of the pedestrian and the position of the road boundary from the image input from the image input unit 120, and the image processing unit 130 for collision prediction In the data recording unit 140 that preserves one data, the collision prediction unit 150 that predicts a collision based on the moving direction of a driving car and a pedestrian with the data obtained from the data recording unit 140, and the collision prediction unit 150 When a collision is predicted, the warning processing unit 160 notifies the driver of the collision.

1 shows the concept of the overall system of the present invention, when a driving car enters the child protection area, it notifies the driver that it has entered the child protection area, and the driving direction of the vehicle (Y-axis) and the recognized movement direction of the pedestrian It is a device that detects (X-axis movement) and warns the driver of a collision if their travel directions are predicted to cross each other.

As shown in FIG. 2 , the driving vehicle acquires the GPS coordinates of the current location in real time, and determines whether the current GPS coordinates belong to the GPS coordinates in the child protection zone through the location finding unit 110 . When it is determined that the child has entered the child protection area, the warning processing unit 160 notifies the driver of the entrance to the child protection area, and then the image input unit 120, the image processing unit 130, and the data record unit 140 for collision prediction and warning notification. , the collision prediction unit 150 is started.

As shown in FIG. 3, when a driving car enters the child protection zone, an image of a pedestrian and a road in front of the driving car is acquired through the image input unit 120 from this time, and the image processing unit 130 is configured with an image input unit ( 120), a dynamic object that is a pedestrian is searched for, and the position of the pedestrian in the frame is calculated as the coordinates of the X and Y axes. In addition, the boundary line of the road is also detected, and the boundary line start coordinates forming this boundary line and boundary line end coordinates indicating the end of the boundary line are calculated as X-axis and Y-axis coordinates. The pedestrian coordinates and road boundary coordinates found through the image processing unit 130 are stored in the data recording unit 140 and transmitted to the collision prediction unit 150 .

4 is a block diagram showing the collision prediction unit 150 as a processing unit for predicting a collision between a vehicle and a pedestrian through data stored in the image recording unit 140. The X-axis and Y-axis coordinates of the pedestrian are directed to the coordinates of the road boundary. In other words, when the X-axis coordinate moves in the '+' direction, it is determined as a pedestrian attention situation and transmitted to the warning processing unit 160 to notify the driver of pedestrian attention. After that, when the X-axis coordinate of the pedestrian continues to move in the '+' direction and crosses the X-axis, which is the boundary coordinate of the road, a collision warning is notified to the driver through the warning processing unit 160 .

The location finding unit 110 detects the location of the vehicle with GPS coordinates in real time while the vehicle is running, and the location of the vehicle is outside the coordinates of the child protection zone. The recording unit 140 , the collision prediction unit 150 , and the warning processing unit 160 are terminated.

In the above, specific embodiments have been shown and described. However, it is not limited only to the above-described embodiments, and those of ordinary skill in the art to which the invention pertains can make various changes without departing from the spirit of the invention described in the claims below. .
