Description

[0001] The present invention relates to a pass assisting apparatus and method,

Embodiments of the present invention are directed to a method and apparatus for detecting movement of an object in a collision hazard area such as an intersection and providing detected information to another object.

Today, traffic lights indicate whether pedestrians and vehicles can pass by using lights, lights, and blinking lights of three lamps to maintain traffic order. The driver of the vehicle passes the crosswalk when the vehicle is a traffic signal, and passes the crosswalk when the pedestrian is a signal that can be traversed.

However, such a traffic light has a problem that it can not be guaranteed whether it is really safe when a pedestrian or a vehicle actually travels according to a signal displayed by the traffic light. That is, although the traffic light indicates a traffic signal for a certain pedestrian or a vehicle, there is a problem that it does not guarantee whether another pedestrian or vehicle around the traffic light moves in accordance with the signal.

1 and 2 schematically illustrate a traffic assisting system according to an embodiment of the present invention.

1 and 2, a traffic aiding system according to an embodiment of the present invention includes a traffic assisting apparatus 10 and a traffic assisting apparatus 10 installed at one point of a collision dangerous area 1 such as an intersection And display means 400a for displaying the generated notification information.

In the present invention, the collision danger area (1) may mean a region where there is a possibility of collision between a person and a transportation means. For example, the collision danger zone 1 may be an area such as a crosswalk.

On the other hand, the collision danger zone (1) may mean an area where there is a possibility of collision between the transportation means. For example, the collision dangerous zone 1 may be an area such as an intersection where the direction of travel of the transportation means changes according to a signal. In this case, one or more passageway aids 10 may be distributed at appropriate locations so that there is no rectangular area in the collision hazard zone 1. [ The aiding device 10 according to an embodiment of the present invention may include a motion sensing unit 100, a notification information generating unit 200, and an announcement information providing unit 300. [ The motion detection unit 100 may detect information about an object and an object moving within a predetermined threshold distance from one point in the collision dangerous area 1. [ The alert information generation unit 200 may generate alert information when the detected object satisfies predetermined conditions using the information about the object detected by the motion detection unit 100. [ The notification information providing unit 300 may provide the notification information generated by the notification information generating unit 200 to one or more display means disposed in the collision dangerous area 1. [

However, the classification of the motion detection unit 100, the notification information generating unit 200, and the notification information providing unit 300 may be classified as a convenience / functional classification, and the configurations are not physically divided clearly , The functions performed in the respective configurations may be performed in duplicate, or some configurations may be omitted and included in other configurations. For example, the notification information generating unit 200 and the notification information providing unit 300 may be integrated into one notification information unit.

The motion sensing unit 100 according to an embodiment of the present invention can detect information about objects and objects moving within a predetermined threshold distance from any one point in the collision dangerous area 1. [

The motion detection unit 100 may include various means for detecting an object. For example, the motion detection unit 100 may include an object detection unit using an LADAR sensor (Laser Detection And Ranging Sensor). At this time, the LADAR Sensor can measure the distance to one point of the object by emitting pulse laser light toward the object and detecting the reflected light or scattered light.

The motion detection unit 100 may include object detection means for providing an image including distance information to an object such as a distance camera. Also, the motion sensing unit 100 may include object detection means for providing a normal RGB image, an infrared image, and the like.

However, the present invention is not limited thereto, and the object detecting means may be configured differently depending on the installation place and / or use purpose of the passageway assistant. For example, a more precise object detection is required for a complicated intersection having a lot of traffic and human traffic, so that a LADAR sensor among the above object detecting means can be used. However, a relatively relaxed object detection means can be used for the transportation means and the rural roads where the passage of people is rare, so that a distance camera or the like among the above object detection means can be used.

The motion sensing unit 100 may include driving means for rotating the object detecting means described above horizontally or vertically. For example, the driving means may be a pan tilt head that rotates the object detection means horizontally and / or vertically to enable object detection in all directions (all directions).

In the present invention, the collision danger zone (1) may include a place where a risk of collision between a person and a transportation means such as a crosswalk or a risk of collision between transportation means such as an intersection, as described above. 'Any one point' in the collision dangerous area 1 may refer to a point where the passageway 10, i.e., the motion sensing unit 100, according to an embodiment of the present invention is installed. Also, 'any one point' may be any one point within the collision hazard zone (1). Accordingly, the motion sensing unit 100 can detect information about objects and objects moving in a region (hereinafter referred to as a sensing region) within a predetermined threshold distance from a point where the passageway assistant 10 is installed or an arbitrary point.

At this time, the critical distance may be set by the user depending on the environment in which the passageway assistant 10 is installed. For example, when the collision dangerous area 1 is a road having a large number of lanes or an intersection with a large number of intersecting roads, the critical distance may be set to be relatively long. However, when the collision dangerous zone 1 is a road or the like having a relatively small number of lanes, such as a one-way road, the critical distance may be set to be relatively short. This critical distance can be set by the user.

The motion sensing unit 100 can detect the type of the moving object in the sensing area as information about the object. For example, when the automobile is moving in the sensing area, the motion sensing unit 100 detects the movement of the object, and can detect that the type of the object is automobile as information about the object.

On the other hand, when a person is moving in the sensing area, the motion sensing unit 100 detects the motion of the object and can detect that the type of the object is a person as information about the object. The information on the object detected by the motion sensing unit 100 can be used by the notification information generating unit 200 described later to generate notification information.

The motion detection unit 100 may detect information about the type of object by various methods. For example, when the motion sensing unit 100 includes means for measuring a distance to an object such as the above-described LADAR Sensor or a distance camera, the motion sensing unit 100 may acquire distance information to an object acquired by each sensing means The object type can be detected by generating the three-dimensional shape of the object based on the generated three-dimensional shape and determining the similarity between the generated three-dimensional shape and the pre-stored three-dimensional shape.

When the motion sensing unit 100 includes a means for providing an RGB image or an infrared image, the motion sensing unit 100 generates a two-dimensional shape of the object based on the image acquired by each sensing means, The kind of the object can be detected by judging the similarity between the generated two-dimensional shape and the previously stored two-dimensional shape. However, it should be understood that the present invention is not limited thereto.

The alert information generation unit 200 may generate alert information when an object satisfies a predetermined condition by using information on the object detected by the motion sensing unit 100 according to an embodiment of the present invention.

For example, when the object detected by the motion sensing unit 100 is the transportation means, the notification information generating unit 200 may calculate the moving speed of the object based on the information about the object sensed by the motion sensing unit 100. [ At this time, the notification information generating unit 200 can generate notification information including information on the calculated movement speed when the calculated movement speed of the transportation means is equal to or greater than a predetermined threshold speed.

In the present invention, 'transportation means' may mean all means for traveling on a road including an automobile. Thus, 'transportation means' may include cars, buses, trucks, motorcycles and bicycles.

In the present invention, 'notification information' means information to be displayed on the display means 400, that is, the first display means 401 and the second display means 402, which will be described later. At this time, the 'notification information' may be composed of letters, figures or a combination thereof.

Meanwhile, when the object detected by the motion sensing unit 100 is a person, the notification information generating unit 200 can detect the position of the object based on the information about the object sensed by the motion sensing unit 100. At this time, the notification information generating unit 200 can generate notification information including information about the detected position when the detected person's position is within a predetermined area. At this time, the 'predetermined area' may be an area such as a road where there is a risk of collision with a transportation means when a person is located.

The notification information generation unit 200 can generate notification information differently according to the type and location of the display means for displaying the notification information. For example, it is assumed that a car approaching a predetermined critical velocity or more, which is 50 km / h from the viewing direction in the collision dangerous area 1, is detected. In this case, the alert information generation unit 200 can generate alert information such as "detection of a car approaching at 50 km / h in the viewing direction" as alert information to be displayed on the first display means 401 for a person. Also, the notification information generating unit 200 may generate notification information such as "Beware of viewing direction conflict" as notification information to be displayed on the second display means 402 for other transportation means. At this time, the announcement information generation unit 200 generates notifications indicating absolute directions such as "viewing direction ", as well as the " 3 o'clock direction "," "May be used to generate notification information.

The alert information generation unit 200 may further include the number of detected objects in the alert information.

The alert information providing unit 300 may provide the alert information generated by the alert information generating unit 200 to one or more display means disposed in the collision dangerous area 1. [

At this time, the passageway assistant 10 including the notification information providing unit 300 and the display unit 400 may be connected through a network. The network described in the present invention can be used in a wide variety of applications, for example, a wireless network, a wired network, a public network such as the Internet, a private network, a global system for mobile communication network (GSM) a packet radio network (GPRS), a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a cellular network, a public switched telephone network PSTN, a personal area network, Bluetooth, Wi-Fi Direct, Near Field communication, Ultra Wide band, a combination of these, But it is not limited to these.

The display means 400 according to an embodiment of the present invention can display the first display means 401 located in the visual field range of the person in the collision dangerous area 1 and the first display means 401 located in the visual range of the transportation means in the collision dangerous area 1 And second display means 402 for displaying the second display means.

In the present invention, the first display means 401 and the second display means 402 of the display means 400 may mean two screens physically separated. For example, the first display means 401 and the second display means 402 may be constituted by separate display devices. In this case, the second display means 402 may be arranged to be positioned in the field of view of the transportation means so that the first display means 401 is located in the field of view of the person.

On the other hand, the first display means 401 and the second display means 402 of the display means 400 mean a region divided into one screen within a range in which the visual range of the person and the visual range of the means of transportation coincide with each other It is possible. For example, the first display means 401 and the second display means 402 may mean two windows configured in a PIP (Picture in Picture) mode in one display means.

The first display means 401 and the second display means 402 may be installed adjacent to a traffic light for a person and a traffic light for a traffic means, respectively. In other words, when a person moves on a collision dangerous area 1 such as an intersection, both the person moving on foot and the person manipulating the traffic means watch the traffic light and move according to the traffic light. You can provide everyone with assistance information about the traffic.

The aiding device 10 according to an embodiment of the present invention can operate in conjunction with a traffic signal. For example, when a person crosses a pedestrian crossing due to a traffic signal, the detection of the object for the pedestrian crossing area may be temporarily stopped, and the second display means 402 may display notification information such as "walking signal ". In addition, the first display means 401 can display the notification information about whether or not the transportation means approaching the crosswalk exists.

Of course, the aiding device 10 according to an embodiment of the present invention may operate independently of a traffic signal.

The passageway assistant 10 according to another embodiment of the present invention may further include an acoustic alarm means (not shown) in addition to the display means 400. [ The notification information generation unit 200 outputs an alarm sound through an acoustic alarm means (not shown) when the detected traveling speed of the transportation means is equal to or greater than a predetermined threshold speed or when the detected person is located on the road, The risk of collision can be notified to all of the unspecified number of objects in the object (1).

3 to 4 are diagrams illustrating an exemplary situation for explaining the operation of the passageway assistant 10 according to an embodiment of the present invention.

Fig. 3 is a diagram showing an exemplary situation for explaining the operation of the passenger assisting apparatus 10, in which a plurality of vehicles and a plurality of persons are located at an intersection as the collision dangerous zone 1. Fig.

3 to 4, there are two cars 501, 502, three persons 601, 602, 603 at an intersection, and four display means 400a, 400b, 400c, Are located at the respective vertexes of the formed rectangles. It is also assumed that each display means includes display means (first display means) located in the field of view of two persons and display means (second display means) located in the field of view of one transportation means. That is, in the case of the display means 400a, it includes two first display means 401a and 401b for a person and a second display means 402a for one transportation means. However, the present invention is not limited to the configuration of the display means 400a. In the following, 401a to 401h denote first display means for a person, and 402a to 402d denote second display means for a transportation means .

If the motion sensing unit 100 detects the automobile 501 approaching the intersection at 50 km / h in the + y direction under the above-described assumption, the notification information generation unit 200 generates the notification information It is possible to calculate the moving speed of the automobile 501 using the information on the vehicle speed. At this time, the alert information generating unit 200 determines whether the calculated moving speed of the car 501 is equal to or greater than a predetermined threshold speed, and if the moving speed of the car 501 is equal to or greater than the threshold speed, It is possible to generate notification information including information on the speed. At this time, the notification information generating unit 200 may generate notification information differently according to the type and position of the display means for displaying the notification information. For example, as notification information to be displayed on the first display means 401e for the person 602, it is possible to generate notification information such as "vehicle detection approaching at 50km / h from the left side ". It is also possible to generate notification information such as "vehicle detection approaching at 50 km / h from the right side " as notification information for display on the first display means 401d for the person 603. Furthermore, it is also possible to generate notification information such as "forward vehicle and collision warning" as notification information for displaying on the second display means 402c for the automobile 502. [

If the motion detection unit 100 detects the person 601 in the collision danger area, the notification information generation unit 200 generates the notification information using the information about the object detected by the motion detection unit 100, It is possible to detect the position of the optical disc 601. At this time, the alert information generation unit 200 can generate alert information including the location information of the person 601 if the detected person 601 is located within a predetermined area, that is, on a road. The notification information generating unit 200 can generate notification information differently according to the type and position of the display unit to be displayed, as described above. For example, as notification information to be displayed on the second display means 402b for the automobile 501, it is possible to generate notification information such as "pedestrian and collision warning in front of ". Also, as notification information for displaying on the first display means 401h or 401a for the person 601, "detection of a car approaching 50 km / h from the left side" or "detection of a car approaching 50 km / h from the right side" The same notification information can be generated.

3 to FIG. 4, the collision danger area is a range of intersection, but the present invention is not limited thereto. For example, when the traffic assisting system according to an embodiment of the present invention is installed in a part where a crosswalk of a general road is not an intersection, the traffic assisting system includes a traffic assisting device 10, first display means 401b and 401c, And second display means 402a, 402c. As shown in FIG. 4, the travel assistance system according to the present invention can be applied to various impending dangerous areas, that is, intersections, and the like.

5 to 7 are flowcharts for explaining a traffic aiding method performed by the traffic assisting apparatus 10 of Fig. Hereinafter, detailed description of the contents overlapping with those described in Figs. 1 to 4 will be omitted.

Referring to FIG. 5, the motion sensing unit 100 according to an exemplary embodiment of the present invention may detect information about objects and objects moving within a predetermined threshold distance from any one point in the collision dangerous area 1 (S51). As described above, the motion detection unit 100 may include detection means including distance information to an object such as an LADAR sensor, a distance camera, and the like. Also, the motion sensing unit 100 may include object detection means for providing a normal RGB image, an infrared image, and the like. Meanwhile, the motion sensing unit 100 may include a pan tilt head as a driving means capable of horizontally or vertically rotating the object detecting means. Therefore, the motion sensing unit 100 can detect an object existing in the collision dangerous area while rotating horizontally and / or vertically. At this time, the motion sensing unit 100 may detect information about one or more objects at a time.

The alert information generating unit 200 according to an embodiment of the present invention can generate alert information when an object satisfies predetermined conditions using information about the object detected by the motion sensing unit 100 ). The alert information providing unit 300 according to the embodiment of the present invention may provide the alert information generated by the alert information generating unit 200 to one or more display means disposed in the collision dangerous area 1 (S53) . Steps S52 and S53 will be described in detail with reference to FIGS. 6 to 7. FIG.

6 is a flowchart for explaining a traffic assisting method when the object detected by the motion sensing unit 100 is the transportation means.

If the position of the detected person is within the predetermined area, the notification information generation unit 200 may generate notification information including information about the detected position (S524). At this time, the 'predetermined area' may be an area such as a road where there is a risk of collision with a transportation means when a person is located. The 'notification information' means information to be displayed on the display means 400, that is, the first display means 401 and the second display means 402.
