Image projection apparatus configured to project an image on a road surface
Information related to a vehicle can be displayed by projecting an image based on the information on a road surface or the like. An image projection apparatus that projects an image includes: an acquisition unit that acquires information to be displayed; and an image projection unit that projects the image based on the information to be displayed acquired by the acquisition unit.
1. An image projection apparatus comprising:
one or more sensors configured to acquire information relating to a vehicle;
a projector configured to project an image on a road surface,
a processor communicatively coupled to a navigation device, the one or more sensors and the projector,
wherein the projector is further configured to project the image based on information acquired by the one or more sensors and information from the navigation device received by the processor, and
wherein, when the image includes a character image based on the information from the navigation device and a traveling speed of the vehicle acquired by the one or more sensors is greater than a predetermined speed, the projector does not project the image on the road surface, and
wherein, when the image does not include the character image based on the information from the navigation device and the traveling speed of the vehicle acquired by the one or more sensors is greater than the predetermined speed, the projector projects the image on the road surface.
2. The image projection apparatus according to claim 1 ,
wherein the processor controls the projector to project the image to different projection positions in accordance with the information from the navigation device.
3. The image projection apparatus according to claim 2 ,
wherein the projection positions include a driving lane of the vehicle, an opposite lane of the vehicle, and a position other than the driving lane or the opposite lane.
4. The image projection apparatus according to claim 2 ,
wherein the processor controls the projector to project alert information received from the navigation device to a portion of the road surface of an opposite lane of the vehicle.
5. The image projection apparatus according to claim 2 ,
wherein the processor controls the projector to project distance information to a destination received from the navigation device to a position other than a lane of the road surface.
6. The image projection apparatus according to claim 2 ,
wherein the processor controls the projector to project at least one of a traveling direction information of the vehicle, a traveling speed information of the vehicle, and remaining fuel information of the vehicle to a portion of the road surface of a driving lane of the vehicle.
7. An image projection method comprising the steps of:
acquiring information relating to a vehicle;
communicating with a navigation device; and
projecting an image onto a road surface,
wherein the image is based on the information relating to the vehicle and information received by the navigation device,
wherein, when the image includes a character image based on the information from the navigation device and a traveling speed of the vehicle is greater than a predetermined speed, the image is not projected onto the road surface,
wherein, when the image does not include the character image based on the information from the navigation device and the traveling speed of the vehicle acquired by the one or more sensors is greater than the predetermined speed, the image is projected onto the road surface.
8. The image projection method according to claim 7 ,
wherein the image is projected to different projection positions in accordance with the information from the navigation device.
9. The image projection method according to claim 8 ,
wherein the projection positions include a driving lane of the vehicle, an opposite lane of the vehicle, and a position other than the driving lane or the opposite lane.
10. The image projection method according to claim 8 , further comprising the step of:
projecting alert information received from the navigation device to a portion of the road surface of an opposite lane of the vehicle.
11. The image projection method according to claim 8 , further comprising the step of:
projecting distance information to a destination received from the navigation device to a position other than a lane of the road surface.
12. The image projection method according to claim 8 , further comprising the step
projecting at least one of a traveling direction information of the vehicle, a traveling speed information of the vehicle, and a remaining fuel information of the vehicle to a portion of the road surface of a driving lane of the vehicle.
