However, the route guidance image providing server 100 shown in FIG. 2 is only one embodiment of the present invention, and various modifications can be made based on the elements shown in FIG. 2. In this embodiment, One of ordinary skill in the art will understand. For example, the components and functions provided within the components may be combined into a smaller number of components or further separated into additional components.

 The image collecting unit 110 collects a plurality of road image images to which the location information is mapped from the plurality of image providing terminals 300. At this time, the collected road image may be an image photographed by the black box 301 installed in the vehicle, a photographed by a camera built in the wireless communication terminals 302 and 303, The photographed image may include position information of the road.

The image analysis unit 120 may map the road image captured based on the location information of the road image to the road information of the map data. For example, in the case of a road image including a point having a latitude of 35.131660 and a hardness of 126.890144, the image analysis unit 120 may map the latitude and longitude of the road image to latitude and longitude of the map data.

The image analysis unit 120 divides the collected road image and generates a sculpture image for each road. The image analysis unit 120 may divide the road image captured based on the predetermined point on the road information. At this time, the predetermined point may include at least one of an intersection, a branch point, an overpass, an underpass, a knot, and a toll gate. For example, when an intersection and an overpass are included in the collected road image, the image analysis unit 120 divides the image from the start point to the intersection of the collected road image into the first piece image, and displays the image from the intersection to the overpass Can be divided into the second piece image, and the image from the flyover to the destination can be divided into the third piece image. In addition, the image analyzer 120 recognizes the milestones included in the collected road image, and can generate a piece-by-road image for each road based on the recognized milestones. For example, when the straight line is displayed on the milestone, when the 'Hannam Bridge', the 'Nonhyun Station', the left turn, the 'High Speed Terminal', the 'Banpo IC', the right turn and the 'COEX' are displayed, The accuracy of the road image analysis can be improved by recognizing characters of 'Hannam Bridge', 'Nonhyeon Station', 'Express Terminal', 'Banpo IC' and 'COEX'

The request receiving unit 130 receives a route guidance request including a source and a destination from the video request terminal 200.

The image synthesizing unit 140 calculates the passing road based on the starting point and the destination. At this time, the image synthesizing unit 140 can calculate the passing route by recognizing the optimum distance, the shortest distance, the expected time, etc. between the start point and the destination. In addition, the image synthesizing unit 140 synthesizes a plurality of pieces of road images corresponding to roads. For example, suppose that the departure point of a vehicle is 'home', the destination is 'school', and intersections and overpasses are located between 'home' and 'school'. The image synthesizer 140 calculates the passage route between the 'home' and the 'school', and then loads the first road-specific piece image between the 'home' and the intersection from the database 160, And the third road-specific piece image between the overpass and the 'school' can be retrieved from the database 160. The image synthesis unit 140 may synthesize the first road-specific piece image, the second road-specific piece image, and the third road-specific piece image loaded from the database 160 into one image. In this case, the first road-specific piece image, the second road-specific piece image, and the third road-specific piece image may be individually photographed images from a plurality of image providing terminals 300 installed in different vehicles.

When a plurality of sculpture images for each road exist for each road, the image synthesizing unit 140 can use a sculpture image having a high priority. At this time, the priority order may be determined based on at least one of the image quality of the piece-of-road image, the shooting date, the traveling speed at the time of photographing, and the screen occupancy rate of other vehicles. For example, suppose that there are "A" and "B" road-by-road sculpture images for the same road. The image synthesizing unit 140 may assign priorities to the road-specific sculpture images of the image quality or high image quality satisfying a certain level of 'A' and 'B'. Alternatively, the image synthesizing unit 140 may assign a priority to the piece-by-road sculpture image having the latest date of photographing date among 'A' and 'B'. Alternatively, the image synthesizing unit 140 may prioritize the piece-by-road sculptural images having a lower occupancy rate based on the occupancy rate of the other vehicles among 'A' and 'B' displayed on the screen. Alternatively, the image combining unit 140 may assign priority to the piece-by-road image in accordance with the traveling speed during the photographing of 'A' and 'B'. For example, in the case of an alleyway, priority can be given to the piece-by-road sculpture images of the vehicles traveling at low speeds, and in the case of the national roads, priority can be given to the sculpture images of the roads of the constant- In addition, the image synthesizing unit 140 may give priorities to the piece-by-road image taken during the day, which is shorter than the night among 'A' and 'B'.

The image transmission unit 150 transmits the synthesized piece image to the image request terminal 200.

The request receiving unit 130 may receive a video change request for a certain section from the video requesting terminal 200. For example, when a video change request for a certain section is received from the video request terminal 200, the video composition unit 140 may re-synthesize a piece-by-road piece image for a certain section. The image synthesis unit 140 may change the image of the corresponding section from the database 160 and re-synthesize the image with the road-specific piece image for another section. At this time, the image synthesizing unit 140 can increase the priority of the piece image for each road, which is changed for a certain section, and lower the priority of the piece image for each road that has been transmitted but has been replaced. The image transmission unit 150 may transmit the re-synthesized piece image to the image request terminal 200. [
