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

1 is a configuration diagram of a POI (Point Of Interest) related moving picture providing system according to an embodiment of the present invention. Referring to FIG. 1, the POI-related moving image providing system 1 may include a video providing terminal 100, a POI video server 200, and a video request terminal 300. The video providing terminal 100, the POI video server 200, and the video request terminal 300 shown in FIG. 1 illustratively show the components that can be controlled by the POI-related moving picture providing system 1.

Each component of the POI-associated moving picture system 1 of Fig. 1 is generally connected via a network. For example, as shown in FIG. 1, the image providing terminal 100 may be connected to the POI-related image providing server 200 through a network. Also, the video request terminal 300 may be connected to the POI-related video providing server 200 through the network.

An example of such a network is Wi-Fi, the Internet, a LAN (Local Area Network), a Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), 3G, 4G, LTE and the like.

The image providing terminal 100 captures an image of a specific point of interest (POI) and transmits the captured POI image to the POI image server 200 manually or automatically. At this time, the image providing terminal 100 may generate position tracking data including the position (e.g., latitude and longitude) of the image providing terminal 100 and time information when generating the POI photographed image. The location tracking data may be, for example, a file generated in the form of a Global Positioning System (GPS) value in a format such as GPX (GPS eXchange), KML (Keyhole Markup Language)

One example of the image providing terminal 100 may be a black box device mounted on a vehicle so that the POI can be photographed. An example of the image providing terminal 100 is a PCS (Personal Communication System), a GSM (Global System for Mobile communications), a PDC (Personal Digital Cellular), a PHS Such as International Mobile Telecommunication-2000, Code Division Multiple Access (CDMA) -2000, W-Code Division Multiple Access (W-CDMA), Wibro (Wireless Broadband Internet) terminals, smart phones, A guaranteed wireless communication device, which may be a device equipped with a video photographing function and a position tracking function. In addition, one example of the image providing terminal 100 may include all kinds of handheld based wireless communication devices such as a smart pad, a tablet PC, and the like.

The POI image server 200 collects the POI photographed image and the position tracking data from the image providing terminal 100. The location tracking data may be, for example, a Global Positioning System (GPS) value generated in a format such as GPX (GPS eXchange), KML (Keyhole Markup Language) At this time, the POI image server 200 can deliver the image collection policy to the image providing terminal 100 before or after collecting the POI image and the position tracking data.

The POI image server 200 can extract location information and time information by parsing the location tracking data and extract a plurality of thumbnails from the POI photographed image. At this time, extracted location information (e.g., latitude and longitude), time information, and a plurality of thumbnails can be stored in the database, and the database stores the content ID of the POI photographed image, the URL where the POI photographed image is stored, The movement trajectory of the POI photographed image, and the photographed time information of the POI photographed image can be correlated and stored.

The POI video server 200 may store and store a plurality of thumbnails and position information. To this end, the POI image server 200 can compare the tracking time information extracted from the position tracking data with the photographing time information extracted from the POI photographed image to determine which thumbnail matches with which position information.

The POI video server 200 receives a search request for the POI from the video request terminal 300. At this time, the search request may include at least one of a keyword, area designation information, and movement locus information. For example, a keyword may indicate a place name, an address, a name, and the like. The area designation information may be generated by drawing a rectangle, a polygon, or a circle for a specific area on a map, or by selecting a specific point. The movement locus information may be generated by drawing a movement path on a map or the like.

The POI video server 200 may display a plurality of thumbnails on the map data and provide the thumbnails to the video request terminal 300. In this case, when the selection of one of the plurality of thumbnails is received from the video request terminal 300, the POI video server 200 may transmit the POI photographed image for the corresponding thumbnail to the video request terminal 300 have.
