Navigation system and navigation method
In a navigation system, a data center is connected to a plurality of vehicles via a communication network. The data center receives video data and stores the received video data in a storage device, the received video data being data of a video captured by a drive recorder and provided from a first vehicle among the plurality of vehicles, the first vehicle having a destination that is set such that route guidance until arrival at the destination cannot be accomplished by the navigation device, the first vehicle having arrived at the destination. The data center transmits the video data stored in the storage device to a second vehicle among the plurality of vehicles, the second vehicle having the destination set in the navigation device. The navigation device of the second vehicle performs guidance to the destination by replaying the received video after the route guidance around the destination is terminated.
1 . A navigation system configured to be connected to a plurality of vehicles, the navigation system comprising:
a storage device; and
a processing device comprising at least one processor configured to:
receive, from a first vehicle among the plurality of vehicles, video data;
store the received video data in the storage device, the received video data being captured by a drive recorder of the first vehicle during a time period starting from termination of route guidance of the first vehicle until arrival of the first vehicle at a destination; and
transmit the video data stored in the storage device to a second vehicle among the plurality of vehicles, the second vehicle having the destination set as a destination setting,
wherein a video of the video data is played at the second vehicle for navigation to the destination after route guidance of the second vehicle is terminated.
2 . The navigation system according to claim 1 , wherein a playing speed of the video played at the second vehicle is adjusted in accordance with a speed of the second vehicle such that a picture captured at a point that the second vehicle reaches after a predetermined time is displayed.
3 . The navigation system according to claim 1 , wherein the at least one processor is configured to:
accumulate, in the storage device, a plurality of pieces of video data regarding a same destination received from two or more vehicles; and
select video data to be transmitted to the second vehicle from the plurality of pieces of video data regarding the same destination accumulated in the storage device and update the video data to be transmitted to the second vehicle.
4 . The navigation system according to claim 3 , wherein the at least one processor is configured to:
compare the video data received from the first vehicle with the plurality of pieces of video data regarding the same destination accumulated in the storage device; and
in response to a determination that the video data received from the first vehicle is different from the plurality of pieces of video data regarding the same destination accumulated in the storage device, delete the video data received from the first vehicle.
5 . A method for a navigation system including a storage device and a processing device, the navigation system being configured to be connected to a plurality of vehicles, the method comprising:
receiving, from a first vehicle among the plurality of vehicles, a video;
storing the received video in the storage device, the received video being captured by a drive recorder of the first vehicle during a time period starting from termination of route guidance of the first vehicle until arrival of the first vehicle at a destination; and
transmitting the video stored in the storage device to a second vehicle among the plurality of vehicles, the second vehicle having the destination set as a destination setting,
wherein the video is played at the second vehicle for navigation to the destination after route guidance of the second vehicle is terminated.
6 . The navigation system according to claim 1 , wherein the route guidance of the first vehicle and the route guidance of the second vehicle are based on at least one of: a pre-stored map or a satellite-based system.
