Apparatus and method for displaying buliding data around the junction when driving in an alley}

The present invention relates to an apparatus and method for displaying buildings around an intersection when driving on three roads. In the case of an intersection entry point without prior information about a landmark or point of interest, the present invention uses a building name or photorealistic image for a small building or house or villa. The present invention relates to an apparatus and method for displaying buildings around an intersection when driving on three roads, allowing real-time and realistic route guidance by being superimposed on a map.

In general, navigation stores information on actual roads, buildings, and facilities as numerical map data in a certain format in the navigation terminal and matches the map data according to the coordinates of the vehicle's current location received from GPS, and the route to the destination for the moving object. Is guided through the screen.

In addition to navigation, the vehicle black box, which is widely used by drivers, captures images around the vehicle with an equipped camera and records it as a video, thereby providing information necessary to grasp the situation and the situation at the time of an accident such as a traffic accident.

Korean Patent Registration No. 10-0979640, a prior art,'A method and apparatus for real-life enlarged expression according to location' receives location information of a moving object from a GPS satellite and enters a specific road where the moving object is virtually divided based on the received location information. The present invention relates to a technology for determining whether to be located in a first access area among areas, extracting and displaying image information of a first access area mapped to a first access area according to a determination result.

However, it is determined whether the moving object is in a virtually divided entry area while driving on a specific road, and displays different images according to each preset entry area, and a landmark or point of interest is mapped to the navigation as map information. In the case of driving on a narrow alleyway that is not stored, there is a problem that the driver misses the turn guidance when entering the intersection.

In addition, there is a limitation in the capacity to create and store all photorealistic images corresponding to the route in the navigation device, and there is a problem that the image information must be updated at least when updating the map DB of the navigation system in order to represent the latest image. .

The present invention, which was devised to solve the problems of the prior art as described above, is designated as a landmark of an intersection entry point, among many cases where map information on a landmark or a point of interest is insufficient when driving on a three road such as an alleyway. It is intended to provide a three-dimensional and realistic rotation guide at an intersection because the name of the building is enlarged and displayed for small buildings, houses or villas, etc. There is this.

In addition, since the present invention extracts and communicates only an image necessary for guidance on entering an intersection, there is another object of enabling a rotation guide at an intersection in real time by reducing a communication load and data processing time.

An object of the present invention is to provide an apparatus for displaying buildings around an intersection while driving on three roads, a control unit that determines whether a building name of an intersection entry point exists in map data in front of a vehicle's path, and receives a video image captured from a black box and transmits it to a server. A communication unit to perform, an image storage unit that stores the real image received from the server and a matched image, an image extracting unit that generates an extracted image from the real image and the matched image, and displays the extracted image by superimposing it on a map of the navigation, When the building name is present in the map data, the building name is enlarged and displayed with the extracted image by a display unit for displaying the building name along with the extracted image.

In addition, another object of the present invention is a method for displaying buildings around an intersection when driving on three roads, the first step of checking whether a building name of an intersection entry point exists in the map data in front of a path of a vehicle, and the building name is in the map data. If present, the second step of expanding and displaying the building name, a third step of requesting a real image of the intersection entry point from the server, a fourth step of generating an extracted image required for guidance on entering the intersection from the real image, black A fifth step of transmitting a video image captured from a box to the server, a sixth step of generating a matched image by determining whether the location coordinates included in the information of the video image coincide with the entrance point of the intersection, and generating the matched image. It is achieved by a method for displaying buildings around an intersection when driving on a three road, comprising: a seventh step of generating an extracted image received from a server and an eighth step of outputting the extracted image to match a map.

Accordingly, the method of displaying buildings around an intersection when driving on a three road of the present invention is a small building or house that is not designated as a landmark while there are many cases where map information about a landmark or a point of interest is insufficient when entering an intersection when driving on a three road. Since it is guided to be displayed by superimposing on the map using the name of the building or the photorealistic image of the villa, etc., there is an effect that it is possible to realistically guide the rotation at the intersection.

In addition, since the present invention extracts and communicates only an image necessary for guidance on entering an intersection, there is another effect of reducing the communication load and data processing time, thereby providing rotation guidance at the intersection in real time.

The terms or words used in the specification and claims should not be construed as being limited to their usual or dictionary meanings, and the inventor may appropriately define the concept of terms in order to describe his own invention in the best way. It should be interpreted as a meaning and concept consistent with the technical idea of the present invention on the basis of the principle that there is.

Accordingly, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention, and do not represent all the technical spirit of the present invention. It should be understood that there may be equivalents and variations.

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

1 is a configuration diagram of an apparatus for displaying buildings around an intersection when driving on a three road according to the present invention. As shown in FIG. 1, the present invention includes a vehicle navigation 100, a server 200, and a black box 300. It is composed.

The navigation 100 includes a function that is provided inside the vehicle to set a starting point and a destination, set a route, and connect to a network through a wireless communication connection with the server 200.

Specifically, the control unit 110 for determining whether the building name of the intersection entry point exists in the map data in the case of reaching the intersection entry point in the middle of guiding the route of three roads such as an alleyway, A communication unit 120 that receives the video image captured from the black box 300 and transmits it to the server 200, an image storage unit 130 that stores the live image received from the server 200 and the matched image, and the live image And an image extraction unit 140 for generating an extracted image from the image and the matched image, and a display unit 150 for expanding and displaying the building name or superimposing the extracted image on a map of the navigation system.

In particular, the control unit 110 enlarges and displays the building name when the building name exists in the map data stored in the navigation 100 and the building name at the intersection entry point, and the map data does not exist. In this case, the real image is requested to the server 200, and the server 200 may be configured as a separate image server or may utilize big data.

Preferably, if the building name does not exist in the map data, only the extracted image will be displayed, but if there is, the building name is enlarged and superimposed on the map together with the extracted image.

On the other hand, when there is no real image in the server 200, the black box ( 300).

In addition, the video image received in this way is transmitted to the server 200 through the communication unit 120. When the location coordinates included in the information of the video image transmitted to the server 200 coincide with the intersection entry point, a request is made to the server 200 to generate the video at this time as a matched image.

The communication unit 120 receives the real image and the matched image from the server 200 and stores it in the image storage unit 130.

The image extracting unit 140 extracts only the information of the surrounding buildings in the direction according to the traveling route of the vehicle, including the intersection entry point, with respect to the photorealistic image and the matching image stored in the image storage unit 130. At this time, in proportion to the scale, only the height of the building that can be confirmed by the driver's field of view is extracted based on the point where the road and the building meet.

On the other hand, in general, descriptions of components included in the navigation device 100 will be omitted.

2 is a flowchart of a method for displaying buildings around an intersection when driving on three roads according to the present invention. As shown in Fig. 2, three roads such as narrow alleyways that lack information on landmarks or points of interest (POI) while the vehicle is driving according to the route search and route guidance When entering and reaching the intersection, it is checked whether the building name exists in the map data at the intersection entry point (S110), and if the building name exists, the building name is enlarged and displayed on the display unit 150 (S120).

If the building name is an intersection point that is not in the map data, a search is requested to the server 200 to search for a real image of the building at the intersection point (S130), and a rotation guide at the intersection point is provided from the received real image. Only necessary image information is cropped (hereinafter referred to as extraction) (S140).

In detail, only the surrounding building information in the direction according to the path of the vehicle to be guided, including the intersection entry point, is extracted from the photorealistic image. In this case, the extracted image is proportional to the scale while the road and the building are Based on the point of encounter, only the height of the building that can be confirmed by the driver's field of view is extracted.

On the other hand, when the building name corresponding to the intersection point is not in the map data or the real image does not exist in the server 200 or the big data, an image captured by a camera provided in the black box 300 in the vehicle The image is received and transmitted to the server 200 (S150).

At this time, since the captured video image has a large data capacity and is difficult to transmit using a mobile communication network, it is first converted into a low-capacity format to be received.

Next, by analyzing the location coordinates included in the information of the video image, it is checked whether it matches the intersection entry point, and if it is an image around the intersection, the image at this time is generated as a matched image (S160), and the navigation 100 is The matched image is received and an extracted image is generated in the same manner as in the step (S140) (S170).

Finally, object information of the extracted image having only the minimum image information generated in the (S140) and (S170) steps is extracted, and an application programming interface (API) of HTML5 (Hyper Text Markup Language 5) is used. Matched on the implemented web-based vector map and drawn in real time (S180).

At this time, as the map becomes smaller and the extracted image is drawn, as in the prior art, the user may experience confusion. Therefore, the size of the map is not changed and the extracted image is matched to the map the driver is looking at and overlapped to show the moving means. The road you are going on is made to appear realistically so that the driver does not pass the turn guidance.

3 is an embodiment of extracting an image in the method for displaying buildings around an intersection when driving on a three road according to the present invention. As shown in Figure 2, in order to reduce the amount of image information communicated between the server 200 and the navigation 100, the surrounding buildings in the direction (left turn, right turn) that the vehicle travels at a turn point such as an intersection The extracted image is generated by extracting from the actual image only for information and only up to the height of the building that can be confirmed by the driver's field of view.

That is, if the guide path set by searching is extracted in proportion to the scale up to a height of about 1.2 meters based on the intersection of the road and the building, and the direction of progress is the right at the intersection, the right side of the intersection including the intersection. It is possible to communicate with a smaller capacity by extracting only the real-world image of the surrounding area.

4 is a first exemplary view showing an embodiment of a method for displaying buildings around an intersection when driving on a three road according to the present invention. It is checked whether the building name at the intersection entry point exists, and if it exists, the building name is enlarged and displayed. Show.

5 and 6 are a second exemplary diagram and a third exemplary diagram showing an embodiment of a method for displaying buildings around an intersection when driving on a three road according to the present invention. When the building name of the intersection entry point does not exist, a real picture of the intersection entry point The image is requested to the server, and the extracted image required for guidance is extracted from the received real image and output to match the map.

As shown in Fig. 5, when the vehicle entrance direction according to the route guidance at the intersection is the left side of the intersection, only the photorealistic image of the left side including the entrance point of the intersection is extracted and superimposed on the map. At this time, the driver's field of view The photorealistic image is extracted and displayed only up to the height of the building that can be confirmed by.

FIG. 6 is a diagram illustrating only the actual image on the right side including the entry point of the intersection when the vehicle entrance direction according to the route guidance at the intersection is the right side of the intersection.

In this way, when driving on a three road such as an alley, there are many small buildings, houses, or villas that are not designated as landmarks, so when driving on a three road according to the present invention, accurate route guidance can be provided to the driver by the method of displaying buildings around the intersection. In addition, since only necessary images are communicated and real images are superimposed on the map and displayed, it is possible to guide turns at intersections in real time and realistically.

The present invention has been shown and described with a preferred embodiment as described above, but is not limited to the above-described embodiment, and within the scope of the spirit of the present invention to those of ordinary skill in the art. Various changes and modifications will be possible.
