At this time, the first vehicle terminal 100-1 checks the sub-section in which the other vehicle terminal 100-N is located, and transmits the drawing information to the edge cloud 400 in charge of the sub-section. In addition, the first vehicle terminal 100-1 transmits the identification information of the other vehicle terminal 100 -N that provides the image currently being displayed to the edge cloud 400. In FIG. 8, the image being played in the first vehicle terminal 100-1 is illustrated as an image of the second vehicle terminal 100-2. Accordingly, in step S805, identification information of the second vehicle terminal 100-2 Is transmitted to the edge cloud 400.

Subsequently, the bypass path matching unit 430 of the edge cloud 400 checks the drawing information, generates the drawing information as a bypass path, and matches the bypass path with the image of the second vehicle terminal 100-2. Do (S807). The detour path matching unit 430 may display a detour route in a direction from a start point to an end point of the drawing information, and match the detour route displaying an arrow in the end point direction with the image. For example, the bypass path 52 as shown in FIG. 5B may be matched with the image of the second vehicle terminal 100-2. The bypass route matching unit 430 is matching information on the bypass route, and identifies sequential coordinate values representing the bypass route (ie, coordinate values drawn by the user) and the second vehicle terminal 100-2 You can store information together. In addition, the bypass path matching unit 430 may match the image so that the bypass path is temporarily valid only for a predetermined time (eg, 10 seconds). That is, the bypass route matching unit 430 may match the bypass route with the image only for a predetermined time, and when the predetermined time is exceeded, the bypass route may be removed from the image.

Subsequently, the detour route matching unit 430 sends a message informing that the detour route is matched to the image of the second vehicle terminal 100-2 to the third vehicle terminal 100-3, which is another vehicle terminal located in the same sub-section. Transmit (S809). In other words, the terminal information acquisition unit 410 periodically receives and stores a list of vehicle terminals located in the area covered by the edge cloud 400 from the route guidance device 200, and the bypass route matching unit 430 includes the Based on the list of vehicle terminals acquired by the terminal information acquisition unit 410, a terminal transmitting a message indicating that the detour path has been matched may be specified.

When the third vehicle terminal 100-3 receives a message indicating that the detour route has been matched, the driver recognizes that the detour route is matched with the corresponding image by displaying an effect such as blinking the image or changing the color. I can make it. The third vehicle terminal 100-3 may receive a selection of an image playback icon of the second vehicle terminal 100-2 matched with the detour route from the driver (S811 ).

Then, the second vehicle terminal 100-2 checks the identification information of the second vehicle terminal 100-2 linked with the play icon and the identification information of the edge cloud 400 linked to the sub-section, and a plurality of The video request message is transmitted to the edge cloud 400 having the identification information among the edge clouds 400 of (S813). The video request message includes identification information of the second vehicle terminal 100-2 linked to the play icon.

Subsequently, the image providing unit 420 of the edge cloud 400 checks the identification information of the second vehicle terminal 100-2 included in the image request message (S815). And after forming a session with each of the second vehicle terminal 100-2 and the third vehicle terminal 100-3, a real-time video is requested from the second vehicle terminal 100-2, and the second vehicle terminal 100 The surrounding image being photographed in real time in -2) is received from the second vehicle terminal 100-2 (S817, S819).

As the image of the second vehicle terminal 100-2 and the detour path are matched, the image providing unit 420 checks the matched detour route (S821), and the detour route and the second vehicle terminal 100 The real-time image of -2) is transmitted to the third vehicle terminal 100-3 (S823).
