Road condition management system and road condition management method
First Claim
1. A road condition management system for managing a road condition, the road condition management system comprising:
- an on-board device; and
an information server, whereinthe on-board device includes;
a camera configured to be attached to a vehicle to photograph an outside of the vehicle;
an image recognition unit that applies image recognition for detecting a road condition to a photographed image obtained by photographing by the camera;
a transmission image information generation unit that generates transmission image information including the photographed image;
a road condition information database having stored therein road condition information; and
a transmission image information output unit that outputs the transmission image information when a recognition result by the image recognition unit is different from the road condition information stored in the road condition information database, andthe information server includes;
a reception unit that receives the transmission image information;
a photographed image output unit that outputs the photographed image included in the transmission image information to enable a checker to visually recognize the photographed image;
an input unit for the checker to input a check result of the photographed image output from the photographed image output unit;
a road condition management information database having stored therein reference images as road condition management information for managing a road condition; and
a reference selection unit that selects a reference image corresponding to a photographed image from the road condition management information database, whereinthe photographed image output unit outputs, together with the photographed image, the reference image selected by the reference selection unit.

Abstract
The present invention provides a road condition management system that can grasp an accurate state of a road condition and reduce a burden on a checker. A road facility management system for managing road facilities includes an on-board device and an information server. The on-board device includes a camera attached to a vehicle to photograph the outside of the vehicle, an image recognition unit that applies image recognition for detecting road facilities to a photographed image, a transmission image information generation unit that generates transmission image information including the photographed image, a road facility information database having stored therein road facility information, and a transmission unit that outputs the transmission image information if a recognition result by the image recognition unit is different from the road facility information stored in the road facility information database.

14. An on-board device belonging to a road condition management system for managing a road condition with an information server, the information server outputting, together with a reference image as road condition management information for managing a road condition, a photographed image included in transmission image information outputted from the on-board device to enable a checker to visually recognize the photographed image, the on-board device comprising:
-
a camera configured to be attached to a vehicle to photograph an outside of the vehicle; an image recognition unit that applies image recognition for detecting a road condition to a photographed image obtained by photographing by the camera; a transmission image information generation unit that generates transmission image information including the photographed image; a road condition information database having stored therein road condition information; and a transmission image information output unit that outputs the transmission image information when a recognition result by the image recognition unit is different from the road condition information stored in the road condition information database.

16. A road condition management method executed using a road condition management system including an on-board device and an information server, the road condition management method comprising:
-
in the on-board device, photographing an outside of a vehicle with a camera; applying image recognition for detecting a road condition to a photographed image obtained by photographing by the camera; and outputting transmission image information including the photographed image when a result of the image recognition is different from road condition information stored in a database of the on-board device, and in the information server, receiving the transmission image information; outputting the photographed image included in the transmission image information to enable a checker to visually recognize the photographed image; selecting a reference image corresponding to the photographed image from a road condition management information database having stored therein reference images as road condition management information for managing a road condition; outputting the selected reference image together with the photographed image; and the checker checking the output photographed image and inputting a check result.
