Display control device

1. A display control device comprising:

an image acquisition unit that is provided to a vehicle and acquires a display target image that is at least one of a front image acquired from a front image capture unit that captures a region including a front of the vehicle and a rear image acquired from a rear image capture unit that captures a region including a rear of the vehicle;

a projection plane acquisition unit that acquires a three-dimensional virtual projection plane to which the display target image is projectable, the three-dimensional virtual projection plane including at least a side surface that rises in a height direction from a ground contact surface of the vehicle;

a correction unit that, in a case where the display target image acquired by the image acquisition unit is projected on the virtual projection plane, corrects a projection position of the display target image to a second direction, which is from a first coordinate corresponding to a position where the virtual projection plane intersects with a first virtual straight line extending in a first direction corresponding to a vehicle length direction of the vehicle from the front image capture unit or the rear image capture unit that captures the display target image to a second coordinate corresponding to a position where the virtual projection plane intersects with a virtual reference line extending in the first direction that is apart from the first virtual straight line in a vehicle width direction of the vehicle; and

an image synthesis unit that projects the display target image on a corrected projection position, and generates a three-dimensional image.

2. The display control device according to claim 1 , wherein

the correction unit acquires a correction ratio for correcting the projection position to the second direction on the basis of a first distance in the second direction between the second coordinate and a fourth coordinate where the virtual projection plane intersects with a second virtual straight line connecting between a process target image capture unit that captures the display target image and a third coordinate where the virtual reference line intersects with a virtual reference plane set at a predetermined distance from the process target image capture unit in the first direction, and a second distance in the second direction between the first virtual straight line and the virtual reference line.

3. The display control device according to claim 2 , wherein the virtual reference line extends in the first direction along a left side surface or a right side surface of a vehicle body of the vehicle.

4. The display control device according to claim 2 , wherein

the image acquisition unit further acquires a side display target image corresponding to at least one of a left side image acquired from a left side image capture unit that captures a region including a left side of the vehicle and a right side image acquired from a right side image capture unit that captures a region including a right side of the vehicle,

the virtual reference line extends in the first direction from a position overlapping with the left side image capture unit or the right side image capture unit in the vehicle width direction, and

the image synthesis unit combines the side display target image with the display target image corrected by the correction unit, and generates the three-dimensional image.

5. A display control device comprising:

an image acquisition unit that is provided to a vehicle and acquires a display target image, the display target image being at least one of a left side image acquired from a left side image capture unit that captures a region including a left side of the vehicle and a right side image acquired from a right side image capture unit that captures a region including a right side of the vehicle;

a projection plane acquisition unit that acquires a three-dimensional virtual projection plane to which the display target image is projectable, the three-dimensional virtual projection plane including at least a side surface that rises in a height direction from a ground contact surface of the vehicle;

a correction unit that, in a case where the display target image acquired by the image acquisition unit is projected on the virtual projection plane, corrects a projection position of the display target image to a second direction, which is from a first coordinate corresponding to a position where the virtual projection plane intersects with a first virtual straight line extending in a first direction corresponding to a vehicle width direction of the vehicle from the left side image capture unit or the right side image capture unit that captures the display target image to a second coordinate corresponding to a position where the virtual projection plane intersects with a virtual reference line extending in the first direction that is apart from the first virtual straight line in a vehicle length direction of the vehicle; and

an image synthesis unit that projects the display target image on a corrected projection position, and generates a three-dimensional image.

6. The display control device according to claim 5 , wherein the correction unit acquires a correction ratio for correcting the projection position to the second direction on the basis of a first distance in the second direction between the second coordinate and a fourth coordinate where the virtual projection plane intersects with a second virtual straight line connecting between a process target image capture unit that captures the display target image and a third coordinate where the virtual reference line intersects with a virtual reference plane set at a predetermined distance from the process target image capture unit in the first direction, and a second distance in the second direction between the first virtual straight line and the virtual reference line.

7. The display control device according to claim 6 , wherein the virtual reference line extends in the first direction along a front surface or a rear surface of a vehicle body of the vehicle.

8. The display control device according to claim 6 , wherein

the image acquisition unit further acquires a display target image in a front-rear direction that is at least one of a front image acquired from a front image capture unit that captures a region including a front of the vehicle and a rear image acquired from a rear image capture unit that captures a region including a rear of the vehicle,

the virtual reference line extends in the first direction from a position overlapping with the front image capture unit or the rear image capture unit in the vehicle length direction, and

the image synthesis unit combines the display target image in the front-rear direction with the display target image corrected by the correction unit, and generates the three-dimensional image.

9. The display control device according to claim 1 , wherein the correction unit changes the correction of the projection position in accordance with a height from the ground contact surface of the vehicle.

10. The display control device according to claim 5 , wherein the correction unit changes the correction of the projection position in accordance with a height from the ground contact surface of the vehicle.
