Abstract
A display assistance device detects the steering angle of a vehicle by using a steering angle sensor, and changes the position of a virtual viewpoint behind the host vehicle based on the detected steering angle. Then, the display assistance device converts images captured using a plurality of cameras such as a front camera and a rear camera into an overhead image of a downward view from the virtual viewpoint, and displays the converted overhead image on a display with a host vehicle icon superimposed on the overhead image, the host vehicle icon indicating the position of the vehicle.
Claims12
A display assistance device that converts images captured by a plurality of cameras installed on a vehicle into an overhead image of a downward view from a virtual viewpoint in air, and displays the overhead image on a display with a host vehicle icon superimposed on the overhead image, the host vehicle icon indicating a position of the vehicle, the display assistance device comprising:
- a computer that determines whether or not the vehicle is making a lane change from a travel lane in which the vehicle is traveling to a next lane next to the travel lane, and changes a position of the virtual viewpoint if determining that the vehicle is making the lane change,
- wherein the computer changes the position of the virtual viewpoint when the position of the virtual viewpoint moves out of a host vehicle lane,
- the computer does not change the position of the virtual viewpoint when the position of the virtual viewpoint does not move out of the host vehicle lane, and
- in a case where the vehicle is making a lane change from a travel lane in which the vehicle is traveling to a next lane next to the travel lane, the computer changes the position of the virtual viewpoint toward the next lane.
A display assistance method involving converting images captured by a plurality of cameras installed on a vehicle into an overhead image of a downward view from a virtual viewpoint in air, and displaying the overhead image on a display with a host vehicle icon superimposed on the overhead image, the host vehicle icon indicating a position of the vehicle, the display assistance method comprising:
- a first step of determining whether or not the vehicle is making a lane change from a travel lane in which the vehicle is traveling to a next lane next to the travel lane;
- and
- a second step of changing a position of the virtual viewpoint if determining that the vehicle is making the lane change,
- wherein in the second step, the position of the virtual viewpoint is changed in a case where the position of the virtual viewpoint moves out of a host vehicle lane,
- wherein in the second step, the position of the virtual viewpoint is not changed in a case where the position of the virtual viewpoint does not move out of the host vehicle lane, and
- wherein in a case where the vehicle is making a lane change from a travel lane in which the vehicle is traveling to a next lane next to the travel lane, the changes the position of the virtual viewpoint toward the next lane.
A display assistance device that converts images captured by a plurality of cameras installed on a vehicle into an overhead image of a downward view from a virtual viewpoint in air, and displays the overhead image on a display with a host vehicle icon superimposed on the overhead image, the host vehicle icon indicating a position of the vehicle, the display assistance device comprising:
- a computer that determines whether or not the vehicle is making a lane change from a travel lane in which the vehicle is traveling to a next lane next to the travel lane, and changes a position of the virtual viewpoint if determining that the vehicle is making the lane change,
- wherein the computer changes the position of the virtual viewpoint when the position of the virtual viewpoint moves out of a host vehicle lane,
- the computer does not change the position of the virtual viewpoint when the position of the virtual viewpoint does not move out of the host vehicle lane, and
- the computer sets the position of the virtual viewpoint as a position relative to the host vehicle in accordance with a speed of the host vehicle.
