Abstract

A vehicle surroundings monitoring apparatus includes a processing device. The processing device outputs a surrounding image as viewed from an eyepoint behind a host vehicle, including a current location of the host vehicle, to a display device mounted on the host vehicle on the basis of an image captured by a camera located a predetermined distance behind the current location of the host vehicle while the host vehicle is travelling forward or the host vehicle is stopped.

Claims

1. A vehicle surroundings monitoring apparatus comprising:

a camera that is mounted on a vehicle;

a display device that is mounted on the vehicle;

a processing device that is mounted on the vehicle,

the processing device configured to;

output a surrounding image as viewed from an eyepoint behind the vehicle to the display device while the vehicle is travelling forward or the vehicle is stopped, the surrounding image including a current location of the vehicle,

output the surrounding image based on a past image captured by the camera at a location that is a predetermined distance behind the current location of the vehicle, and the predetermined distance corresponding to a distance from the vehicle to the eyepoint behind the vehicle, wherein

the past image captured by the camera at the location that is the predetermined distance behind the current location of the vehicle is a first image captured by the camera at the time when the vehicle passed through a point that is the predetermined distance behind the current location of the vehicle, and

generate the surrounding image by synthesizing the first image with a third image that shows a surrounding mobile unit; and

a detecting device configured to detect a relative positional relationship between the vehicle and the surrounding mobile unit and that outputs the relative positional relationship to the processing device,

wherein the processing device is further configured to determine a position at which the third image is synthesized on the basis of the current relative positional relationship between the surrounding mobile unit and the vehicle, output from the detecting device.

2. The vehicle surroundings monitoring apparatus according to claim 1, wherein

the camera captures an area ahead with reference to a forward travelling direction of the vehicle.

3. The vehicle surroundings monitoring apparatus according to claim 1, wherein

the processing device generates the surrounding image by synthesizing the first image with a second image that shows the vehicle.

4. The vehicle surroundings monitoring apparatus according to claim 3, wherein

the processing device determines a position at which the second image is synthesized based on the current location of the vehicle.

5. The vehicle surroundings monitoring apparatus according to claim 1, wherein

the processing device generates the surrounding image by erasing an image of a mobile unit in the first image.

6. The vehicle surroundings monitoring apparatus according to claim 1, wherein

the processing device changes the predetermined distance.

7. A vehicle surroundings monitoring method, the vehicle having a camera mounted on the vehicle, a processing device, a detecting device and a display device mounted on the vehicle, the method comprising:

acquiring, by the camera, a first image captured at a location that is a predetermined distance behind a current location of a vehicle;

generating, by the processing device, a surrounding image as viewed from an eyepoint behind the vehicle, including the current location of the vehicle, by using the first image which is a past image captured by the camera at a time when the vehicle was located the predetermined distance behind the current location of the vehicle, the predetermined distance corresponding to a distance from the vehicle to the eyepoint behind the vehicle; and

showing, by the display device, the surrounding image while the vehicle is travelling forward or the vehicle is stopped, wherein

the past image captured by the camera at the location that is the predetermined distance behind the current location of the vehicle is a first image captured by the camera at the time when the vehicle passed through a point that is the predetermined distance behind the current location of the vehicle, and

generating the surrounding image by synthesizing the first image with a third image that shows a surrounding mobile unit; and

detecting, by the detecting device, a relative positional relationship between the vehicle and the surrounding mobile unit and outputting the relative positional relationship to the processing device,

determining, by the processing device, a position at which the third image is synthesized on the basis of the current relative positional relationship between the surrounding mobile unit and the vehicle, output from the detecting device.
