Vehicular image projection
A computer is programmed to determine a target area to project, along a planned travel path of a vehicle, a symbol based on detecting a target object. The computer is further programmed to actuate a light source to project the symbol moving within the target area.
1. A computer including a processor and a memory, the memory including instructions such that the processor is programmed to:
detect, from a vehicle, a target object along a planned travel path of the vehicle;
determine a line-of-sight from the target object to a surface;
determine a target area on the surface to project a symbol based on an intersection of the surface and the line-of-sight of the target object; and
actuate a light source to project the symbol within the target area based on a determination that the vehicle is within a first maximum distance of a traffic signal and the target object is within a second maximum distance of the traffic signal.
2. The computer of claim 1 , wherein the processor is further programmed to:
determine the target area such that the target area includes the intersection of the surface and the line-of-sight of the target object.
3. The computer of claim 2 , wherein the processor is further programmed to:
determine the target area further such that the target area extends a predetermined extension range on each side of the line-of-sight in a direction perpendicular to the line-of-sight along the surface.
4. The computer of claim 1 , wherein the target area includes the planned travel path.
5. The computer of claim 1 , wherein the processor is further programmed to:
determine the line-of-sight of the target object based on a type of the object.
6. The computer of claim 5 , wherein the type of the target object is a person, and the computer is further programmed to:
determine the line-of-sight of the target object based on facial recognition.
7. The computer of claim 5 , wherein the type of the target object is a person, and the computer is further programmed to:
determine that the person is looking at a second object; and
determine the line-of-sight based on a line extending from the person's face to the second object.
8. The computer of claim 7 , wherein the person is holding the second object.
9. The computer of claim 7 , wherein the second object is a mobile telephone.
10. The computer of claim 5 , wherein the type of the target object is a vehicle, and the computer is further programmed to:
determine a line-of-sight of the target object based on a direction the vehicle is facing.
11. The computer of claim 5 , wherein the type of the target object is a vehicle, and the computer is further programmed to:
determine a line-of-sight of the target object based on a line through a front windshield of the target object towards a road through which the planned travel path passes.
12. The computer of claim 1 , further programmed to move the symbol alternately in a first direction and then a second opposite direction within the target area.
13. The computer of claim 1 , further programmed to actuate the light source further based on a determination that the target object is within a maximum distance of the planned travel path.
14. The computer of claim 1 , further programmed to actuate the light source further based on a determination that the target object is within a maximum distance of the vehicle.
15. The computer of claim 1 , further programmed to actuate the light source based on a determination that the vehicle is stopped at the traffic signal.
16. A method comprising:
detecting, from a vehicle, a target object along a planned travel path of the vehicle;
determining a line-of-sight from the target object to a surface;
determining a target area on the surface to project a symbol based on an intersection of the surface and the line-of-sight of the target object; and
actuating a light source to project the symbol within the target area based on a determination that the vehicle is within a first maximum distance of a traffic signal and the target object is within a second maximum distance of the traffic signal.
17. The method of claim 16 , further comprising:
determining the target area such that the target area includes the intersection of the surface and the line-of-sight of the target object.
18. The method of claim 16 , further comprising: determining the target area such that the target area extends a predetermined extension range on each side of the line-of-sight in a direction perpendicular to the line-of-sight along the surface.
19. The method of claim 16 , further comprising:
determining the line-of-sight of the target object based on a type of the object.
