Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pedestrian detection device and a pedestrian detection method using the pedestrian detection device,

The present invention relates to a pedestrian sensing device for a vehicle, and more particularly to a device for sensing the position of a portable terminal device of a pedestrian and sensing a pedestrian.

A general crosswalk is a part of a road sign or a road sign that is provided for crossing a pedestrian based on the Road Traffic Act. The pedestrian must use it because the crosswalk is intended to protect pedestrians from traffic hazards such as automobiles, The driver of the vehicle is also obliged to suspend the pedestrian when he or she crosses it. At crossings where the vehicle is at great risk, an overpass or transverse underpass may be installed instead of the crosswalk.

On the other hand, in the conventional vehicle, there is no separate protection device for the pedestrian in the vehicle. Therefore, the driver must directly observe the presence of the pedestrian in front of the vehicle during the running of the vehicle and respond to it. Particularly, It is difficult to identify a pedestrian, so that it is not possible to find a pedestrian walking on a lane, and a pedestrian is injured by injuring a pedestrian.

Another problem is that a driver finds a pedestrian late and the driver suddenly manipulates the steering wheel to avoid the pedestrian or suddenly brakes the vehicle, resulting in an accident caused by a collision of the rear vehicle.

A method for improving image quality and a method for detecting a pedestrian using the method are disclosed in Korean Patent Laid-Open Publication No. 10-2012-0056984. The pedestrian sensing method includes generating a plurality of virtual images through coordinate movement with respect to an original image of the image, generating an average image of the plurality of virtual images, Generating an image difference between the original image and an average image, extracting a feature vector and an eigenvalue by performing principal component analysis on the image difference, and setting the eigenvalue to 0, .

According to the image quality improvement method and the pedestrian sensing method using the image quality improvement method, it is possible to determine the current weather through the input image data, and the input image quality is improved by reducing the noise of the input signal in the determined bad weather environment It is possible to provide high quality image information.

However, this method does not provide enough safety information to the driver of the vehicle for pedestrians other than the visual system of the camera mounted on the vehicle.

It is an object of the present invention to provide a technical solution that can provide pedestrian presence information of a pedestrian in an area where bad weather or visibility is not secured to a vehicle driver.

According to an aspect of the present invention, there is provided a pedestrian sensing apparatus comprising: a receiving unit for receiving position information from a portable terminal device of a pedestrian around a vehicle; A display unit for displaying a screen and a position of the pedestrians around the vehicle through position information received through the receiving unit, and displaying a position of a pedestrian present within a predetermined distance from the vehicle among the pedestrians identified, .

The control unit continuously monitors the position of each of the pedestrians, alerts the driver of the vehicle when the pedestrian approaches the vehicle at a predetermined speed or more, and sets the position of the identified pedestrians to a predetermined risk color And displays it on the display unit.

Further, the display unit is a transparent display for projecting the cluster display of the vehicle.

According to another aspect of the present invention, there is provided a method for detecting a pedestrian through a location of a portable terminal device of a pedestrian, comprising the steps of: receiving location information from a portable terminal device of a pedestrian around a vehicle; Determining the position of the pedestrians around the vehicle based on the position of the pedestrians, and displaying the position of the pedestrians on the screen.

In addition, the step of continuously grasping the position of each of the pedestrians may include the steps of continuously grasping the position of each of the pedestrians, and in the case of at least one of the case where the pedestrian exists within a certain distance based on the vehicle, And warning the driver of the vehicle.

The present invention receives positional information from a portable terminal device carried by a pedestrian around a vehicle and can grasp the position of the pedestrian around the vehicle and provides the pedestrian position information to the driver so that a collision accident between the vehicle and the pedestrian Thereby creating an effect of preventing the above-

Particularly, by displaying the identified pedestrian position information on a screen in different colors according to the degree of risk, it is possible to visually display the position information of the pedestrian in an environment where visibility is difficult to obtain and provide it to the driver. You can be alerted by voice or screen when approaching at speed.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a pedestrian sensing device by locating a portable terminal device of a pedestrian according to an embodiment of the present invention. As shown, the pedestrian sensing apparatus includes a receiving unit 100, a display unit 200, and a control unit 300.

The receiving unit 100 can receive GPS information from the portable terminal device as means for receiving positional information from a portable terminal device carried by pedestrians around the vehicle. Alternatively, it can receive a 3G signal including GPS information and a 4G signal.

The display unit 200 is a structure for displaying the position of the pedestrians around the vehicle on the screen. For example, the display unit 200 may be an LCD (Liquid Crystal Display) of an AVN (audio, video, navigation) system for location and route guidance of the vehicle. As another example, the display unit 200 may be a transparent (transparent) display mounted at a predetermined position such that the display of the vehicle instrument cluster is projected, as illustrated in Fig.

The control unit 300 is a control unit mounted on a predetermined position of the vehicle for controlling the entirety of the pedestrian sensing apparatus. The control unit 300 may be implemented as an AVN unit for controlling the vehicle navigation system, and may be implemented as a separate control unit from the AVN unit.

The control unit 300 receives the positional information of the portable terminal device of the pedestrians around the vehicle through the receiver 100 and locates the pedestrians around the vehicle using the received positional information, ). In addition, when the control unit 300 is present in the proximity area on the basis of the vehicle, the control unit 300 can warn the driver through screen display or audio output.

At this time, the control unit 300 can display the position of the pedestrian along with the surrounding building and the road condition in cooperation with the navigation map data for guiding the vehicle location and route.

Hereinafter, the pedestrian sensing method by locating the portable terminal device of the pedestrian will be described in detail with reference to the flowchart of FIG.

First, when the pedestrian detection request signal is received by the vehicle driver, the control unit 300 receives position information from a plurality of portable terminal devices existing within a certain radius (e.g., radius 5 m) around the vehicle (S100). Here, the pedestrian sensing request signal may be a signal by a switch or a button operation of the driver of the vehicle, or a signal by the vehicle driver's voice recognition in the voice recognition system implemented in the vehicle. In addition, many portable terminal devices are portable terminal devices carried by pedestrians within a predetermined radius around the vehicle.

The control unit 300 determines the position of the pedestrians around the vehicle based on the position information received from the plurality of portable terminal devices (S200).

If the detected position of the pedestrian is located within a predetermined radius of the vehicle, the control unit 300 displays the position of the pedestrian through the display unit 200 (S300) (S400).

Here, the predetermined radius of the vehicle periphery may be equal to a predetermined radius at which the location information of the portable terminal device is received at step S100, or may be a predetermined radius (for example, a radius of 3 m) by the user.

In addition, when the control unit 300 exists in a nearby area within a certain distance (for example, a radius of 1 m with respect to the vehicle) on the basis of the vehicle, the control unit 300 can warn the driver of the vehicle through voice output or screen display.

In addition, the control unit 300 determines whether the pedestrian approaches the vehicle at a predetermined speed or more based on the moving direction and the moving speed of the pedestrian based on the positional information of the portable terminal device received in real time (S500).

Specifically, the direction of the movement of the pedestrian can be determined by comparing the position information of the portable terminal device of the received pedestrian with the movement direction of the pedestrian, and the direction of the movement of the pedestrian can be grasped by using the G sensor of the portable terminal device of the pedestrian. Also, the moving speed of the pedestrian can be determined based on the pedestrian displacement and direction of the position information periodically received based on the vehicle.

When the pedestrian approaches the vehicle at a predetermined speed or more, the controller 300 displays the position of the pedestrian on the screen and warns the driver of the vehicle through voice output or screen display (S600).

Furthermore, the control unit 300 can display the pedestrian around the vehicle by differentiating the color of the pedestrian according to the degree of risk. For example, if the risk is divided into three levels, the risk 1 is the safety level if the pedestrian is located at a suitable distance from the vehicle (for example, a radius of 2 m or more on a vehicle basis) And displays the position of the pedestrian in green on the screen as illustrated in Fig. 2 (b).

The danger level 2 is divided into a warning level when the pedestrian is located at a certain distance from the vehicle (for example, a radius of 1 m to 2 m on a vehicle basis), or when the speed of the pedestrian is higher than a predetermined standard, Display the position of the pedestrian in yellow as shown.

The risk level 3 is divided into warning levels when the pedestrian is located at a close distance from the vehicle (for example, within a radius of 1 m on a vehicle basis), and displays the position of the pedestrian in red as illustrated in FIG. 2 (b).

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
