The present invention relates to a recording medium on which a method and a terminal and a program using the same are recorded.

The present invention is a technology that easily informs the driver the location of the vehicle when the driver moves after parking the vehicle. Many techniques for guiding such a parking position have been proposed. For example, there is a technique related to a parking position determining technique using a device with an acceleration sensor, a method of finding a parking position using a parking card, and a parking lot. Various ways of remembering the parking position by using the parking lot infrastructure such as pillars have been presented.

However, as mentioned above, technologies for informing a driver of the location of a parked vehicle have been proposed, but there is no method of informing a parking location using only a mobile device owned by the driver. No description of the location-based system was found.

The present invention is implemented by using a mobile device capable of receiving a GPS owned by the driver, and parking location extraction to maximize the convenience by informing the location of the driver reference vehicle using the coordinates and azimuths of the stored coordinates and the current location after parking. The present invention relates to a recording medium on which a method and a terminal and a program using the same are recorded. The use of such a technology does not require any other communication infrastructure or hardware in the surroundings as in the prior art. The simplicity of construction can be made effective.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

The present invention has been proposed to solve this problem, the parking location extraction method that can be easily identified and guided by parking only the built-in program in the user terminal without building the infrastructure around the terminal and the program using the same is recorded The purpose is to provide a recording medium.

In the parking location determining step, when the latitude and longitude are not determined from the GPS module, the latitude and longitude determined through the location estimation step may be determined as the parking location.

In the current location determination step, if the latitude and longitude are not determined from the GPS module, the latitude and longitude determined through the location estimation step may be recognized as the current location.

In the location estimating step, when the reception of the satellite information of the GPS module is stopped, the latitude and longitude of the subsequent point may be accumulated from the latitude and longitude of the stopped point.

The location extraction step may be updated by recalculating the separation distance from the parking location when the current location is changed.

1 is a flow chart of a parking position extraction method according to an embodiment of the present invention.
2 is a view showing a display of a terminal implemented with the parking position extraction method shown in FIG.

Hereinafter, with reference to the accompanying drawings looks at a parking position extraction method according to a preferred embodiment of the present invention and a recording medium in which a terminal and a program using the same.

1 is a flow chart of a parking position extraction method according to an embodiment of the present invention, the parking position extraction method of the present invention, using the GPS module to determine the latitude and longitude of the user terminal parking position detection step (S200); Determining the current position of the latitude and longitude of the user terminal moved from the parking position by using the GPS module (S300); And a location extraction step (S500) of calculating a separation distance on a rectangular coordinate system or a polar coordinate system from the current location to the parking location by using the identified location information of the parking location and the current location of the user terminal.

In order to guide the parking location using the parking location extraction method of the present invention, the user must have a smartphone or other mobile terminal, and a predetermined request program must be installed on the terminal. Hereinafter, the present invention will be described in detail with respect to the above.

As shown, first, the user operates the GPS module in the terminal. The GPS module continuously receives the longitude, latitude and azimuth of the user terminal through satellite communication. The user terminal may further perform a position estimation step of accumulating latitude and longitude of a later point from the latitude and longitude of a previous point by using the acceleration sensor and the geomagnetic sensor of the user terminal.

Of course, if the GPS module is capable of satellite communication in all areas, the location estimation step may not be performed. However, in an area where the GPS module cannot communicate, it may be necessary to track the location of the current user terminal. In this case, the location of the terminal may be estimated by performing the location tracking step.

That is, in general, when the communication of the GPS module is possible, the GPS sensor receives the location information including the longitude, latitude, and bearing of the current terminal. And using the geomagnetic sensor to accumulate the latitude and longitude of subsequent points from the latitude and longitude of the last point where GPS communication was possible. In addition, at the time when GPS communication is enabled, the position estimation step is ended again so as to always have the most accurate position information every time.

Thereafter, when the user parks the vehicle, the parking is input through the user terminal after the parking is completed. This may be implemented in various ways such as touch or button input or voice input. When the parking is input, the user terminal performs a parking position determining step (S200) of grasping the latitude and longitude of the user terminal using the GPS module.

In this case, when the latitude and longitude are not determined from the GPS module, the latitude and longitude, which are obtained through the location estimation step, may be determined as the parking position.

Then, when the user wants to return to the vehicle after completing a shopping or meeting, the user inputs the vehicle search into the terminal at the current location. If the vehicle search is input, the terminal performs a current position determination step (S300) of grasping the latitude and longitude of the user terminal moved from the parking position using the GPS module, and the parking position and the current position of the user terminal. Using the location information of the position extraction step (S500) for calculating the separation distance on the Cartesian coordinate system or the polar coordinate system from the current position to the parking position.

Here, the current position detection step (S300) also, if the latitude and longitude is not determined from the GPS module to determine the latitude and longitude determined through the position estimation step as the current position. That is, when the satellite module reception of the GPS module is interrupted through the location estimation step, the current location information derived by accumulating latitude and longitude of a later point from the latitude and longitude of the interrupted point is used.

The user terminal calculates the separation distance in the Cartesian coordinate system or the polar coordinate system from the current position to the parking position by using the location information of the parking position and the current position, which converts latitude and longitude into a rangefinder and the distance meter is orthogonal through the azimuth angle. This is converted to the X, Y axis distance in the coordinate system. Or it may be expressed in the polar coordinate system of direction and distance.

On the other hand, the location extraction step (S500) to update by recalculating the separation distance from the parking position when the current position is changed. Specifically, the location extraction step (S500) may be to update the separation distance from the parking position by correcting the change value as much as the current position changes. That is, it may be possible to periodically update the data by re-tracking the position at regular intervals or by reflecting the changed distance in the conventional data.

The location extraction step (S500) may further include a guide step (S600) for guiding the parking position by outputting a separation distance through the user terminal. As shown in FIG. 2, in the guiding step, a vertical distance, a horizontal distance, and a direction are displayed on the user's terminal to induce the user to easily approach the vehicle while being guided in a parking lot or a complicated street. Alternatively, the distance and the direction may be guided by using voice information through a terminal provided in the vehicle. In addition, the guide step to estimate the location of the terminal in real time to update the distance to the vehicle.

The terminal for using the parking location extraction method of the present invention as described above, using the GPS module to grasp the latitude and longitude of the parking location and the current location, respectively, the current location using the identified parking location and the current location information And a control unit for calculating a separation distance on the Cartesian coordinate system or the polar coordinate system from the parking position to the parking position.

When the reception of the satellite information of the GPS module is interrupted, the controller accumulates the latitude and longitude of the subsequent point from the latitude and longitude of the last point determined from the GPS module by using the acceleration sensor and the geomagnetic sensor of the user terminal. At the time of grasping the location and the current location, it is possible to use the location information by the satellite information or the location information by the cumulative calculation depending on whether the GPS module receives the satellite information.

In addition, the recording medium in which a program for executing the parking position extraction method is recorded, the parking position determining step of grasping the latitude and longitude of the user terminal using a GPS module (S200); Determining the current position of the latitude and longitude of the user terminal moved from the parking position by using the GPS module (S300); And a location extraction step (S500) of calculating a separation distance on a rectangular coordinate system or a polar coordinate system from the current location to the parking location by using the identified location information of the parking location and the current location of the user terminal. The recording medium on which a program capable of implementing such a method is recorded will also include an embodiment in a downloadable form, and the parking position extraction method can be implemented by being downloaded and executed in a user terminal.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, 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 following claims It will be apparent to those of ordinary skill in the art.
