Referring to the operation of the augmented reality-based parking guidance system in the indoor parking lot according to the present invention configured as described above are as follows.

First, the indoor parking lot to which the present invention is applied refers to an indoor parking lot such as an apartment house, a hospital, a large shopping mall, a theme park, and the like. Hereinafter, for convenience of description, an indoor parking lot such as an apartment is used as an example in the present invention. It demonstrates by an example.

Residents who live in a common house, such as an apartment, register vehicle information in the parking lot system 300. Here, when the vehicle information is registered, the indoor parking lot route guidance application is downloaded through the communication module 115 through the navigation device 100, and the indoor parking lot route guidance application is downloaded to the information storage unit 108 under the control of the controller 106. do. Similarly, the user downloads the indoor parking lot route guidance application through the smart phone 200 when registering the vehicle information and stores it in the internal memory. In this case, when the vehicle information is registered, the information of the living lake is provided so that the parking is first induced to the parking space closest to the position of the user where he / she agrees to when parking at the indoor parking lot.

After downloading the indoor parking lot path guidance application, the 3D modeling unit 105 performs 3D modeling based on the indoor parking lot design information under the control of the control unit 106 to generate the indoor parking lot 3D modeling information, and the information. Store in the storage 108. The 3D modeling information generated here refers to 3D image data such as visually viewing an actual indoor parking lot.

As shown in FIG. 3, when the vehicle equipped with the navigation device 100 arrives at the entrance of the indoor parking lot of the apartment house such as an apartment, the app switching signal transmitted from the app switching signal generator installed at the entrance of the parking lot is detected by the parking lot recognition unit 102. Receive the signal. Here, the app switching signal generator installed at the entrance of the indoor house parking lot is configured as a beacon (beacon), and generates a beacon signal as the app switching signal.

When the parking lot recognition unit 102 recognizes the beacon signal, the parking lot recognition unit 102 transmits the beacon signal to the control unit 106. When the parking lot recognition signal is input, the controller 106 transmits a control signal to switch the app to the app switching unit 107. The app switching unit 107 automatically draws and executes the indoor parking lot route guidance application pre-registered in the information storage unit 108 when an app control signal for controlling app switching in conjunction with the control unit 106 arrives. Perform an app switch. Here, the control signal may use various control signals. For example, when the electric low signal (0) generated as a control signal may be a signal to switch to the basic app, when the electric high signal (1) may be a signal to switch to the indoor parking lot route guidance application. While running the indoor parking lot guidance application, the user performs operations to search for a new destination or when the power is supplied again after the navigation power is turned off, it is initialized to execute a general app.

In the state of automatically switching to the indoor parking lot guidance application, the camera 103 starts shooting, and the image processing unit 104 processes the indoor parking lot image photographed by the camera 103 with a basic image processing algorithm. The basic image processing algorithm is an image processing technique basically used in the field of camera image processing, and includes a preprocessing process. The image processor 104 detects image brightness from the processed image after performing basic image processing such as preprocessing. Here, the image brightness may use various well-known brightness detection algorithms, and for example, the brightness may be detected by using color values of pixels. Subsequently, when the image brightness is detected, the image brightness value is transmitted to the controller 106.

At the same time, the location information generator 120 receives the location signal generated from the location information generator installed at a predetermined location in the indoor parking lot, generates location information based on the received field strength (RSSI), and transmits the location information to the controller 106. . Here, the location information generator is installed at predetermined intervals in the indoor parking lot, and uses a directional beacon for generating a beacon signal. For example, YG beacons can be used as directional beacons. YG beacons are aviation beacons that use a VHF band of electromagnetic waves to rotate a directional antenna and emit azimuth signals every 30 °. In order to apply this to the present invention, the radio waves are emitted in only one direction in a fixed state at an angle. Alternatively, a device such as a funnel may be mounted at the entrance of a general beacon to have directivity.

That is, the location information generator 120 receives the location signal generated from the location information generator composed of a directional beacon installed at a predetermined position of the indoor parking lot in the beacon signal receiving unit 121 when the indoor parking lot enters. Subsequently, the reception field strength detection unit 122 detects the reception field strength RSSI of the beacon signal received by the beacon signal receiver 121. Next, the beacon signal selection unit 123 compares the reception field strength detected by the reception field strength detection unit 122 with a previously registered reference reception field strength, and only a beacon signal substantially larger than the reference reception field strength is a practical beacon signal. The beacon signal is transmitted to the control unit 106 as a location information signal. Here, the beacon signal includes current location information, and using this information, the current location can be accurately known without using other devices in the indoor parking lot. Since a plurality of beacons are installed in the indoor parking lot, the beacon signal may be received at various places while moving the indoor parking lot. In this case, since accurate position identification is difficult, in the present invention, the position information is obtained by using the directional beacon and the received electric field strength of the beacon signal.

The controller 106 transmits the location information to the indoor location search unit 109 when the specific location information is obtained through the location information generator 120. The indoor location search unit 109 searches for the location of the vehicle based on the transmitted location information. Here, the indoor location search unit 109 searches for the location of the indoor parking lot by substituting the location information into the indoor parking lot 3D modeling information registered in advance in the information storage unit 108. The searched position becomes the current vehicle position in the entire indoor parking lot. Location information is pre-assigned for each area of the 3D modeling information, and the location information is provided to indicate the location of the opposite directional beacons. The searched position information is transmitted to the route image generator 111.

The route image generating unit 111 is interlocked with the control unit 106 to provide the empty parking space information provided from the parking lot system 300, the current location information of the acquired indoor parking lot, the indoor parking lot image information, and the registered vehicle information. Create a route for parking of the indoor parking lot based on. The route image generation unit 111 basically finds the closest empty parking surface in the empty parking space information based on the Dong Ho, the owner of the vehicle, using the vehicle registration information. If an empty parking surface is found, an optimal path is generated from the current position to the empty parking surface in the 3D modeling information of the indoor parking lot. The optimal path generation may use techniques such as the shortest distance and the shortest time performed in the general navigation. When the path is generated, the path information is mapped to the indoor image of the current indoor parking lot acquired by the image processor 104 to generate a 3D path image. At this time, the path guide indicator is also displayed on the 3D path image. 4A to 4C illustrate examples of the 3D path image generated by the path image generator 111 as described above. Where the arrow is the route guidance indicator.

Here, as another feature of the present invention, it is also possible to implement the color of the parking surface using the image brightness value or to implement a variety of colors of the path guide indicator.

For example, the parking surface color implementation unit 110 implements the parking surface color based on the image brightness value provided through the control unit 106. The parking surface color is determined by illuminance using an image brightness value, and the parking surface color is implemented based on the determined illuminance. That is, the color of the parking surface is realized depending on whether the indoor parking lot is dark or bright. Here, the color of the parking surface is implemented as a color look-up table in advance according to the illuminance, and when the image brightness value is detected, it is preferable to extract the parking surface color by searching the color look-up table as an index. The extracted parking surface color information is transmitted to the route image generator 111.

The path image generating unit 111 generates a 3D path image and expresses it directly through the screen display unit 112 to perform path guidance. The 3D path image displayed on the screen display unit 112 is an intuitive image, allowing the user to recognize the information more easily and accurately.

As another method, when the parking surface color information is transmitted, the parking surface image color of the 3D route image is implemented using the parking surface color information provided when generating the 3D route image. That is, when the 3D route image is implemented using the indoor parking lot image photographed by the actual camera, only the color of the parking surface is changed so that the driver can identify the parking surface more accurately. In addition, the route image generator 111 implements a color of the route guide indicator based on the image brightness value. The path guide indicator may be implemented in the form of an indicator look-up table according to the image brightness in advance, and when the image brightness is detected, the color of the guide indicator to be brought in real time may be extracted and used. Here, the route guidance indicator may use an arrow, but in addition to the arrow, it is also possible to use various indicators that are easy for the user to visually recognize.

Accordingly, the driver parks in the empty parking space while moving the vehicle through the 3D route image and the route guide indicator displayed on the screen display unit 112.

When the parking is completed, the parking location information is stored in the information storage unit 108 and transmitted to the parking lot system 300 through the communication module 115. The parking information transmitted to the parking lot system 300 may include a parking image, parking location information, and the like.

On the other hand, when the driver wants to find the parking position of his vehicle later in the state of parking completed, the indoor parking lot route guidance application using the smart phone 200, and inputs the find my car function through the operation unit 101.

When the find my vehicle function is input, the controller 106 obtains parking information in cooperation with the communication module 115, extracts parking location information from the parking information, and then transfers the extracted parking location information to the route image generation unit 111. do. At this time, the smartphone 200 also obtains the location information of the current indoor parking lot through the location information generation unit 120.

When the parking location information is received, the path image generator 111 generates a path from the current location to the vehicle using the acquired location information, the parking location information, and the 3D modeling information. The generated path information also becomes a 3D path image. Subsequently, the path image generator 111 implements the generated 3D path image as an augmented reality (AR) and provides it to the screen display unit 112. In this case, it is assumed that the path image is implemented by augmented reality.

5 is an example of an augmented reality path image implemented in the smartphone as described above.

Therefore, the user can accurately recognize the location of his vehicle using the smart phone 200, the route guidance service to the vehicle by using the smart phone 200 as a navigation device without having to find a parking vehicle directly in the real parking lot Will receive.

This makes it easy and convenient to find a parking vehicle.

As described above, the present invention accurately acquires location information by using a directional beacon and a received signal strength indicator (RSSI) in an indoor parking lot, and based on the acquired location information, an empty parking space is obtained through a 3D image. By providing information, the user can easily park the car.

Also, according to the present invention, when a request for finding a car is requested, a path is generated from the current location to the parking location information, and the generated path is implemented by AR, so that the user can easily recognize the location of the vehicle and the parked vehicle location. It will help you to go easily and accurately.
