Abstract

An information processing device includes a first calculation part configured to calculate a position of a first icon on a transparent screen, the transparent screen being viewed by a driver of a vehicle, the first icon indicating that an obstacle in a path of a vehicle is detected from an image captured by an imaging part provided in the vehicle, the first icon being viewed at a position of the obstacle on a two-dimensional coordinate plane arranged at a lower limit position of the transparent screen, the two-dimensional coordinate plane corresponding to an imaging area of the imaging part, and a second calculation part configured to calculate a position of an end point of an indication line on the transparent screen, the indication line being viewed as extending from a position of the first icon on the transparent screen toward the obstacle.

First claim

What is claimed is:

1. An information processing device, comprising:
a first calculation part configured to calculate a position of a first icon on a transparent screen, the transparent screen being viewed by a driver of a vehicle, the first icon indicating that an obstacle in a path of a vehicle is detected from an image captured by an imaging part provided in the vehicle, the first icon being viewed at a position of the obstacle on a two-dimensional coordinate plane arranged at a lower limit position of the transparent screen, the two-dimensional coordinate plane corresponding to an imaging area of the imaging part;
a second calculation part configured to calculate a position of an end point of an indication line on the transparent screen, the indication line being viewed as extending from a position of the first icon on the transparent screen toward the obstacle, and
a determination part configured to determine whether or not a position of the obstacle is present in an area of the transparent screen, an image of the obstacle being viewed at a position of the first icon on the transparent screen in a case where a position of the obstacle is not present in the transparent screen.

2. The information processing device as claimed in claim 1 , further comprising:
a third calculation part configured to calculate a position of a second icon on the transparent screen in a case where a position of the obstacle is present in an area of the transparent screen, the second icon emphasizing the obstacle, the second icon being viewed at a position of the obstacle.

3. The information processing device as claimed in claim 2 , wherein the third calculation part is configured to calculate a straight line passing through a position of the obstacle and a position of an eye ball of the driver and calculate a position of a point of intersection between a position of the straight line and the transparent screen as a position of the second icon on the transparent screen.

4. The information processing device as claimed in claim 1 , wherein the second calculation part is configured to calculate a straight line passing through a position of the obstacle and a position of an eye ball of the driver and calculate a position of a point of intersection between the straight line and the transparent screen as a position of an end point of the indication line on the transparent screen.

5. The information processing device as claimed in claim 1 , wherein the first icon or an image of the obstacle is viewed as being changed depending on a running speed of the vehicle.

6. An information processing device, comprising:
a first calculation part configured to calculate a position of a first icon on a transparent screen, the transparent screen being viewed by a driver of a vehicle, the first icon indicating that an obstacle in a path of a vehicle is detected from an image captured by an imaging part provided in the vehicle, the first icon being viewed at a position of the obstacle on a two-dimensional coordinate plane arranged at a lower limit position of the transparent screen, the two-dimensional coordinate plane corresponding to an imaging area of the imaging part;
a second calculation part configured to calculate a position of an end point of an indication line on the transparent screen, the indication line being viewed as extending from a position of the first icon on the transparent screen toward the obstacle; and
a fourth calculation part configured to calculate a perimeter line of the two-dimensional coordinate plane, the perimeter line being viewed,
wherein the fourth calculation part is configured to change a perimeter line of the two-dimensional coordinate plane in a direction perpendicular to the transparent screen depending on a running speed of the vehicle.

7. An information processing device, comprising:
a first calculation part configured to calculate a position of a first icon on a transparent screen, the transparent screen being viewed by a driver of a vehicle, the first icon indicating that an obstacle in a path of a vehicle is detected from an image captured by an imaging part provided in the vehicle, the first icon being viewed at a position of the obstacle on a two-dimensional coordinate plane arranged at a lower limit position of the transparent screen, the two-dimensional coordinate plane corresponding to an imaging area of the imaging part; and
a second calculation part configured to calculate a position of an end point of an indication line on the transparent screen, the indication line being viewed as extending from a position of the first icon on the transparent screen toward the obstacle,

wherein the first calculation part is configured to calculate a straight line passing through a position of the obstacle in the two-dimensional coordinate plane and a position of an eye ball of the driver and calculate a position of a point of intersection between a position of the straight line and the transparent screen as a position of the first icon on the transparent screen.

8. An information processing device, comprising:
a first calculation part configured to calculate a position of a first icon on a transparent screen, the transparent screen being viewed by a driver of a vehicle, the first icon indicating that an obstacle in a path of a vehicle is detected from an image captured by an imaging part provided in the vehicle, the first icon being viewed at a position of the obstacle on a two-dimensional coordinate plane arranged at a lower limit position of the transparent screen, the two-dimensional coordinate plane corresponding to an imaging area of the imaging part; and
a second calculation part configured to calculate a position of an end point of an indication line on the transparent screen, the indication line being viewed as extending from a position of the first icon on the transparent screen toward the obstacle, wherein the second calculation part is configured to calculate a first straight line passing through a position of the obstacle and a position of an eye ball of the driver and calculate, as a position of an end point of the indication line on the transparent screen, a position where a straight line passing through a position of a point of intersection between the first straight line and a plane identical to the transparent screen and a position of a point of intersection between a second straight line passing through a position of the obstacle on the two-dimensional coordinate plane and a position of an eye ball of the driver and the transparent screen intersects with a perimeter of the transparent screen.

9. An information processing method, comprising:
a first calculation step to calculate a position of a first icon on a transparent screen, the transparent screen being viewed by a driver of a vehicle, the first icon indicating that an obstacle in a path of a vehicle is detected from an image captured by an imaging part provided in the vehicle, the first icon being viewed at a position of the obstacle on a two-dimensional coordinate plane arranged at a lower limit position of the transparent screen, the two-dimensional coordinate plane corresponding to an imaging area of the imaging part;
a second calculation step to calculate a position of an end point of an indication line on the transparent screen, the indication line being viewed as extending from a position of the first icon on the transparent screen toward the obstacle, and
a determination step to determine whether or not a position of the obstacle is present in an area of the transparent screen, an image of the obstacle being viewed at a position of the first icon on the transparent screen in a case where a position of the obstacle is not present in the transparent screen.
