Abstract

An electronic device includes: a recognition part that recognizes a plurality of signs indicating content of the regulations relating to traveling of a vehicle on the basis of a captured image obtained by capturing a region ahead of the vehicle; a first identification part that identifies, as a corresponding sign, a sign corresponding to a lane in which the vehicle travels among the plurality of signs recognized by the recognition part; and an output part that outputs information corresponding to content of the regulations indicated by the corresponding sign.

First claim

What is claimed is:

1. An electronic device comprising:
a recognition part that recognizes a plurality of signs indicating content of regulations relating to traveling of a vehicle on the basis of a captured image obtained by capturing a region ahead of the vehicle which travels in a road having plural lines for vehicles traveling in a same direction and wherein the plurality of signs are located over the road;
a first identification part that identifies, as a corresponding sign, a sign corresponding to a lane in which the vehicle travels among the plurality of signs recognized by the recognition part; and
an output part that outputs information corresponding to content of the regulations indicated by the corresponding sign, and wherein
the first identification part identifies a position of the lane on which the car vehicle travels on a basis of the captured image, identifies, as the corresponding sign, a sign in a first area immediately above a position of the lane in which the vehicle travels, identifies a sign in a second area on a right side of the first area as the corresponding sign when a sign cannot be recognized in the first area by the recognition part, identifies a sign in a third area on a left side of the first area as the corresponding sign when a sign cannot be recognized in either the first area nor the second area by the recognition part.

2. The electronic device according to claim 1 , wherein
the output part outputs information corresponding to the content of the regulations indicated by the corresponding sign to a display device.

3. The electronic device according to claim 1 , wherein
each of the plurality of signs is a sign indicating content of the same type of regulations in different lanes.

4. The electronic device according to claim 1 , further comprising:
a storage that stores positional information of a plurality of positions included in a plurality of lanes in association with the plurality of lanes; and
a second identification part that identifies a position of the vehicle on the basis of a signal detected by a position sensor mounted on the vehicle, wherein

the first identification part identifies the lane stored in the storage in association with the position identified by the second identification part, and identifies a sign corresponding to the lane as the corresponding sign.

5. An electronic device comprising:
a recognition part that recognizes a plurality of signs indicating content of regulations relating to traveling of a vehicle on the basis of a captured image obtained by capturing a region ahead of the vehicle;
a first identification part that identifies, as a corresponding sign, a sign corresponding to a lane in which the vehicle travels among the plurality of signs recognized by the recognition part; and
an output part that outputs information corresponding to content of the regulations indicated by the corresponding sign, wherein
the first identification part identifies whether the vehicle is a right-hand drive vehicle or a left-hand drive vehicle,
identifies whether the lane in which the vehicle travels has right-hand traffic or left-hand traffic,
identifies a position of a lane in which the vehicle travels on the basis of the captured image, and
identifies a sign on the left side of the identified lane as a corresponding sign when (i) there is no sign immediately above the identified position of the lane, (ii) the vehicle is the left-hand drive vehicle, and (iii) the lane in which the vehicle travels has right-hand traffic.

6. A non-transitory storage medium storing a program causing a computer to execute:
recognizing step, a plurality of signs indicating content of regulations relating to traveling of a vehicle on the basis of a captured image obtained by capturing a region ahead of the vehicle which travels in a road having plural lines for vehicles traveling in a same direction and wherein the plurality of signs are located over the road;
identifying step, as a corresponding sign, a sign corresponding to the lane in which the vehicle travels among the plurality of recognized signs on a basis of the captured image; and
outputting step information corresponding to content of the regulations indicated by the corresponding sign wherein
in the identifying step, a sign in a first area immediately above a position of the lane in which the vehicle travels is identified as the corresponding sign, a sign in a second area on a right side of the first area is identified as the corresponding sign when a sign cannot be recognized in the first area, or a sign in a third area on a left side of the first area is identified as the corresponding sign when a sign cannot be recognized in the first area nor the second area.
