Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a recommended parking position guidance method according to an embodiment of the present invention.

In step S110, the parking position guiding device displays, for each of a plurality of empty prin- cipal parking planes of the plurality of parking planes, at least one of adjacent parking planes, adjacent information indicating the occupancy state of the adjacent parking planes, The recommendation score is calculated based on one.

Here, the parking position guiding device uses at least one of a camera for CCTV (closed circuit TV) installed to photograph the parking surface, an ultrasonic sensor installed on the parking surface, and a pressure sensor attached to the parking surface, It is possible to select a plurality of princesses not parked in the vehicle. On the other hand, the parking surface is an area partitioned so that one vehicle is parked. The princess side is a parking side where the vehicle is not parked on the parking side, and the adjacent parking side is directly adjacent to the princess side, It can be a parking space irrespective of whether or not it is.

Generally, the princess side has a parking side adjacent to either side or front or rear, or there is an adjacent parking side adjacent to both sides (for example, there are pillars or walls on either side) (Eg, there are pillars or walls on the other side), or there is only one parking surface (eg, there are pillars or walls on both sides) There may be cases in which there is no < / RTI > That is, the parking position guiding device can determine the number of adjacent parking surfaces to be one of 0, 1, 2 and 3. At this time, the smaller the number of adjacent parking surfaces, the smaller the need for the driver to consider the parked vehicle on the adjacent parking surface when the vehicle is parked. Therefore, the number of adjacent parking surfaces is determined by considering the ease of parking the driver when the vehicle is parked .

In addition, the adjacent information is information on the occupied state of the vehicle parked on the adjacent parking surface that is in contact with the princessing side. More specifically, the adjacent information includes information on whether or not the vehicle is parked on the adjacent parking surface, and information on the parking distance, which is the distance from the parked vehicle on the adjacent parking surface to the parking line between the adjacent parking surface and the princessing surface can do. At this time, if the adjacent parking surface is empty or the parking interval is wide, it is easier for the driver to park the car on the princess side, so that the neighbor information can be used to consider the ease of parking when the driver parks the vehicle .

In addition, the distance to the driver's doorway of the parking lot may mean the distance from the center of the parking surface to the exit or entrance (e.g., the elevator or emergency stairway of the underground parking lot) at which the driver will be stationed. At this time, the shorter the distance to the driver's doorway of the parking lot is, the more convenient for the driver to walk after the parking, so the distance to the driver's entrance of the parking lot can be used to consider the mobility after the driver parks the vehicle. On the other hand, when the exit of the parking lot and the entrance are distinguished, the distance to the exit can be calculated as an average of the distance to the exit and the distance to the entrance.

Therefore, the recommendation score can be calculated so that the recommendation score increases as the number of adjacent parking spaces decreases and the recommendation score decreases as the number of adjacent parking spaces increases. In addition, the recommendation score can be calculated so that the recommendation score is lowered as the adjacent parking surface is parked or the parking interval is narrower, and the recommendation score is higher as the adjacent parking space is vacant or the parking interval is wider . The recommendation score can be calculated so that the recommendation score decreases as the distance to the driver's entrance to the parking lot becomes shorter and the distance to the driver's entrance to the parking lot becomes shorter.

In another embodiment, when the parking position guiding device calculates the recommended score, the number of adjacent parking faces, the distance from the parked vehicle on the adjacent parking faces included in the adjacent information to the parking lines between the adjacent parking faces A recommendation score can be calculated by applying a predetermined weight to each of at least one of the parking interval and the distance to the entrance.

For example, factors considered to be important among the three factors of consideration for the number of adjacent parking spaces, parking intervals, and distance to the entrance of each driver may be different. Accordingly, the driver can set a weight for each of the above three consideration factors in advance through his smartphone, and the parking position guidance apparatus can calculate the customized recommendation score for each driver by using the set weight.

More specifically, a driver who worries about entrance of a parked vehicle on an adjacent parking surface and a contact accident at the time of departure gives a higher weight to the number of adjacent parking surfaces, so that the number of adjacent parking surfaces is 0 or 1, Can be increased. In addition, a driver who is poor in parking may be given a higher weight in the parking interval, so that the recommendation score of the princess side having a wide parking interval can be increased. In addition, a driver who is uncomfortable to walk can give a higher weight to the distance to the entrance, so that the recommendation score of the princess side having a shorter distance to the entrance can be increased.

On the other hand, the number of the adjacent parking surfaces and the distance to the entrance / exit are factors that do not change once the parking lot is completed, and therefore may be a predetermined value for each parking surface. On the other hand, the parking interval may vary depending on whether the vehicle is parked or parked, and may be a value requiring real-time measurement using a camera or the like. The method of measuring the parking interval will be described later in detail with reference to FIG.

In another embodiment, the recommendation score can be calculated by Equation (1).

[Equation 1]

Here, S is a recommendation score, 3 is a maximum value of the number of adjacent parking planes, Adj is the number of adjacent parking planes,? Is a weight for the number of adjacent parking planes, Gap is a parking interval a, β is a weight for the parking space, Dist _max is the maximum value of the distance to the exit, Dist is a distance from the entrance, γ is a weight for a distance to the exit.

As shown in Equation (1), when the number of adjacent parking spaces Adj is smaller, the recommended score is increased. When the parking gap Gap is wider, the recommended score is higher. When the distance to the driver's entrance of the parking lot is shorter It can be seen that the recommendation score increases.

In step S120, the parking position guiding device selects at least one selected parking surface from a plurality of prin- cipal parking lots based on the recommendation score.

For example, when there are 20 princesses, the parking position guiding device can calculate a recommendation score for each of the 20 princesses. Then, the recommended scores are sorted in descending order, and the selected parking faces can be selected with the three most frequently used recommendation scores.

Finally, in step S130, the parking position guiding device transmits parking position information including information of at least one selective parking surface to the driver.

For example, when the three parking areas are selected, the parking position guiding device can transmit the parking position information including the information of the three selected parking areas to the driver. Further, after the driver receives the parking position information, the driver can park the car by operating the car on the desired princessed car surface among the three selected parking surfaces.

In another embodiment, the parking position information may be displayed on one of a monitor installed in the parking lot, a monitor mounted inside the vehicle, a driver's smartphone and a tablet.

For example, when the vehicle enters the entrance through the parking breaker, the parking position guiding device may transmit the parking position information to a monitor installed in the vicinity of the vehicle entrance to be displayed. Further, the receiving apparatus mounted on the driver's vehicle can receive the parking position information from the parking position guiding apparatus and display it on a monitor (e.g., a navigation monitor or a head-up display (HUD)) mounted on the vehicle. In addition, the driver's smartphone or tablet can receive parking position information from the parking position guidance device and display it on the smartphone or tablet.

At this time, information (e.g., MAC address, IP address, telephone number, ID / Password, etc.) of the driver's receiving apparatus, smart phone, and tablet may be registered in advance in the parking position guiding apparatus together with the vehicle number, When the vehicle enters the parking lot, the parking position guiding device receives the result of recognizing the car number from the license plate recognition device, and can transmit the parking position information to the receiving device, the smartphone, and the tablet registered together with the car number.

In another embodiment, when the parking position information is displayed, on the floor plan of the parking lot, at least one selected parking surface may be distinguished from the remaining parking surfaces.

For example, referring to Fig. 6, a top view of the parking lot is shown. At this time, on the floor plan of the parking lot, the three selective parking planes A3, A4 and A2 screened by the parking position guiding apparatus can be displayed so as to be distinguished from the remaining parking planes. More specifically, in FIG. 6, the three selective parking planes A3, A4 and A2 are displayed in blue, and the remaining parking planes are displayed in green.

As described above, the recommended parking position guiding method according to an embodiment of the present invention has an effect of providing the driver of the vehicle entering the parking lot with information on the optimal parking position based on ease of parking and mobility.

2 is a flowchart illustrating a recommended parking position guiding method according to another embodiment of the present invention.

In step S210, the parking position guiding device receives a parking information request signal, which is a signal requesting the driver to transmit the parking position information.

For example, a driver's smartphone or tablet may be automatically connected to a beacon installed around the entrance of the car park. Then, the smartphone or the tablet can transmit a parking information request signal to the parking position guidance device.

If the GPS coordinates of the driver's smartphone or tablet coincide with the position of the parking lot registered in advance within a predetermined range, the smartphone or tablet can transmit a parking information request signal to the parking position guidance device.

When the GPS coordinates of the driver coincide with the position of the parking lot registered in advance within a predetermined range, an advanced driver assistance system (ADAS) mounted on the vehicle sends a parking information request signal to the parking position guidance device Lt; / RTI >

In another embodiment, when the license plate of the vehicle is recognized by the license plate recognizing device when the driver's vehicle enters the parking lot, the parking position guiding device can receive the recognized information.

At this time, when the recognized vehicle number is a number pre-registered through the smartphone application, the parking position guidance device considers the recognized information to be the same as the parking information request signal, Location information can be transmitted.

In step S220, the parking position guiding device displays, for each of a plurality of the prin- cipal parking lots whose sides are empty among the plurality of parking surfaces, at least the number of adjacent parking faces, the adjacent information indicating occupancy state of the adjacent parking faces, The recommendation score is calculated based on one.

In step S230, the parking position guiding device selects at least one selected parking surface from a plurality of prin- cipal parking lots based on the recommendation score.

Finally, in step S240, the parking position guiding device transmits parking position information including information on at least one selected parking surface to the driver.

At this time, the parking position guiding device can transmit the parking position information to one of the smartphone, the tablet and the driver assistance system of the driver who transmitted the received parking information request signal. On the other hand, the parking position information transmitted to the driver assistance system may be displayed on the internal monitor or HUD of the vehicle that is associated with the driver assistance system.

3 is a flowchart illustrating a method of calculating a parking interval according to an embodiment of the present invention.

5, the adjacent information is information on the occupied state of the parked vehicle 530 on the adjacent parking surface 520 that is in contact with the princessing surface 510, A parking interval 550 indicating the distance from the vehicle 530 parked on the adjacent parking surface 520 to the parking line 540 between the adjacent parking surface 520 and the princessing surface 510, As shown in FIG.

In step S310, the parking position guiding device acquires a target image of the adjacent parking surface 520.

For example, a plurality of cameras may be installed in a parking lot such that each parking surface of each parking lot can be photographed by at least one camera. At this time, the parking position guiding device can select one camera that photographed a specific adjacent parking surface 520 among the plurality of cameras, and receive the target image from the selected camera.

In step S320, the parking position guiding device performs a Hough transform on the target image to straighten the adjacent parking surface.

Here, the Hough transform is a conversion method for extracting a line segment in a method of processing an image. For example, the parking position guiding device can linearly extract pixels having a pixel value similar to the color of the parking line through a Hough transform to the target image, thereby straightening the adjacent parking surface.

Finally, in step S330, the parking position guiding device calculates the minimum interval between the parked car on the adjacent parking side and the parking line between the adjacent parking side of the princess side and the adjacent parking side from the straightened adjacent parking side, and calculates the parking distance.

For example, the number of pixels corresponding to the parking interval can be calculated by using the adjoining parking surface in which the parking position guiding device is straightened. (Number of pixels in the parking space): (Number of pixels corresponding to the parking interval) = (Width of the parking space): (Distance between parking spaces) The length of the parking space can be calculated using a proportional formula such as the length of the parking space.
