Display control device for displaying a plurality of marks based on hypithetical line and a target, display device, display system, vehicle, display control method, and non-transitory storage medium related to same
A display control device comprises a memory and a processor coupled to the memory. The processor is configured to acquire positional information about a target based on detection information of a target detection section that detects the target in surroundings of a vehicle, set a virtual origin in an output range of an output section that outputs an image to a display area provided in a cabin of the vehicle, set a hypothetical line connecting the virtual origin to a position of the positional information, and generate, based on the hypothetical line, a mark that urges caution toward the target and that is overlay displayed on the display area.
1. A display control device comprising:
a memory, and a processor coupled to the memory, wherein the processor is configured to:
acquire positional information about a target based on detection information of a target detection section that detects the target in surroundings of a vehicle;
set a virtual origin in an output range of an output section that outputs an image to a display area provided in a cabin of the vehicle;
set a hypothetical line connecting the virtual origin to a position of the positional information;
generate, on the hypothetical line, based on the hypothetical line, a plurality of marks that urge caution toward the target and that is overlay displayed on the display area, and
change a virtual distance between the plurality of marks according to an actual distance from the vehicle to the target.
2. The display control device of claim 1 , wherein the processor is configured to generate the mark at a position near to the virtual origin so as to be larger than the mark at a position far from the virtual origin.
3. The display control device of claim 1 , wherein the processor is configured to set a position offset from an eyepoint of an occupant of the vehicle in a forward direction of the vehicle as the virtual origin.
4. The display control device of claim 1 , wherein the processor is configured to generate at least one of the mark at a position offset from the virtual origin toward a position of the positional information and lying in the output range.
5. The display control device of claim 1 , wherein the processor is configured to generate the mark at either left or right with respect to the virtual origin.
6. The display control device of claim 1 , wherein the processor is configured to generate the mark as a 3D arrow indicating a direction of the target.
7. The display control device of claim 1 , wherein the processor is further configured to detect a size of the target, and the processor generates the mark based on the size of the detected target.
8. A display device comprising:
the display control device of claim 1 ;
the output section that outputs the image; and
the display area provided in the cabin of the vehicle, on which the image output by the output section is overlay displayed.
9. A display system comprising:
the display device of claim 8 ; and
the target detection section that detects the target in the surroundings of the vehicle and has a detection range wider than the output range output by the output section.
10. A vehicle comprising:
the display system of claim 9 ; and
a windshield that configures the display area.
11. A display control method executed by a processor, the display control method comprising:
acquiring positional information about a target based on detection information of a target detection section that detects the target in surroundings of a vehicle;
setting a virtual origin in an output range of an output section that outputs an image to a display area provided in a cabin of the vehicle;
setting a hypothetical line connecting the virtual origin to a position of the positional information;
generating, on the hypothetical line, based on the hypothetical line, a plurality of marks that urge caution toward the target and that is overlay displayed on the display area, and
changing a virtual distance between the plurality of marks according to an actual distance from the vehicle to the target.
12. A non-transitory storage medium storing a program executable by a processor to perform display control processing, the display control processing comprising:
acquiring positional information about a target based on detection information of a target detection section that detects the target in surroundings of a vehicle;
setting a virtual origin in an output range of an output section that outputs an image to a display area provided in a cabin of the vehicle;
setting a hypothetical line connecting the virtual origin to a position of the positional information;
generating, on the hypothetical line, based on the hypothetical line, a plurality of marks that urge caution toward the target and that is overlay displayed on the display area, and
changing a virtual distance between the plurality of marks according to an actual distance from the vehicle to the target.
