The parking lot is enlarged and many parking surfaces are installed in the parking lot, and when the parking lot is parked on one of the many parking surfaces, it is very difficult for the driver to find a vehicle for departure.

Accordingly, a method of checking the parking position by causing the car horn to ring through the horn function or the app (APP) of the car key has been proposed, but it has a disadvantage in that the driver needs to be within a distance to hear the horn ringing. This was difficult to identify if different (eg my location is on the first basement and the car parking location is on the third basement). In addition, a sudden horn sound in a car has caused inconvenience such as to scare someone near the vehicle.

Although it has been suggested to check the parking location through the location tracking linkage map of the smartphone, it is difficult to determine the exact location such as indoor, parking lot by floor, and there are ways to take pictures of the parking lot. Every time there was an inconvenience to take a parking location-related information (such as parking area display, QR code provided by the parking lot) with a smartphone. In addition, a method of interworking with an unmanned parking system has also been proposed, but it has a limitation that it can be used only in a parking lot to which an unmanned parking system is applied.

The photographing device 210 may generate a photographed image by photographing the front and / or rear of the vehicle 101 when the vehicle 101 is driven.

The photographing device 210 may support a short range communication function including a Bluetooth, and transmit the captured image to the driver's smart phone 201 through the short range communication function.

In this case, the photographing device 210 may transmit the photographed image to the smartphone 201 from a pairing connection point with the smartphone 201 through a short range wireless communication such as Bluetooth. That is, the photographing device 210 may transmit the photographed image to the smartphone 201 according to whether the smartphone device 201 is paired with the smartphone 201.

In contrast, the photographing device 210 may detect whether the starting of the vehicle 101 is off, and when the starting of the vehicle 101 is detected to be off, the starting of the vehicle 101 is performed. Until this is off, it is possible to transmit the captured image taken to the smartphone 201.

In this case, the photographing device 210 may measure the signal strength of the power supplied from the battery of the vehicle 101, and compare the measured signal strength with a preset reference signal strength. As a result of the comparison, when the measured signal strength is weaker than the reference signal strength, the imaging device 210 may detect that the start of the vehicle 101 is turned off.

On the other hand, the signal strength of the power supplied from the battery of the vehicle 101 to the photographing device 210 may be measured by a sensor board mounted on the vehicle 101 itself, in this case the photographing device 210 ) May omit the process of directly measuring the signal strength of the power supplied from the battery of the vehicle 101.

For reference, FIG. 5 is a diagram illustrating an example of an image recording method for securing a storage capacity of the smartphone 201 according to an embodiment of the present invention.

As illustrated in FIG. 6, the application 220 identifies parking position-related information (see “410” in FIG. 4) including the number of floors and a position determining symbol from the photographed image recorded in the previous section 520. Except for the still cut 610 including the identified parking position related information, the remaining captured images recorded in the previous section 520 may be deleted. For reference, FIG. 6 is a diagram illustrating another example of an image recording method for securing a storage capacity of the smartphone 201 according to an embodiment of the present invention.

On the other hand, the application 220 may measure the altitude information corresponding to the position of the smart phone 201 using the altitude sensor mounted on the smart phone 201. In this case, the application 220 may measure the previous altitude information corresponding to the previous position of the smartphone 201 and the current altitude information corresponding to the current position of the smartphone 201, and may update continuously. have.

The application 220 calculates an altitude change value based on the previous altitude information and the current altitude information, and whether the smartphone 201 is moved between layers based on the calculated altitude change value and a preset reference altitude value. Can be determined. The application 220 compares the previous altitude information with the current altitude information when the inter-layer movement of the smart phone 201 is made, and determines the floor information where the smart phone 201 is currently located, and the determined floor Information may be displayed on the screen of the smartphone 201.

On the contrary, the application 220 searches for an access point (AP) near a point in time at which the last photographed image is received from the photographing device 210 and uses a plurality of discovered APs to present the current state of the smartphone 201. Identify locations.

In detail, the application 220 may classify a plurality of AP information collected at a location where the smart phone 201 is located at the time when the vehicle 101 is turned off, by floor. The application 220 assigns a class constant to each AP information classified for each layer based on the signal strength included in the AP information, calculates the total of the class constants for each layer, and has the largest total among them. May be determined as the floor of the point where the smartphone 201 is located.

In this case, the application 220 gives a greater class constant to the AP information when the signal strength included in the AP information is stronger than the reference value, and becomes smaller when the signal strength included in the AP information is weaker than the reference value. A class constant may be given to the AP information.
