Method for displaying a vehicle environment of a vehicle
A method for displaying a vehicle environment of a vehicle, including a detection of the vehicle environment in camera images with the aid of a plurality of cameras; projecting the camera images onto a geometrical projection surface in a virtual space, setting up a depth map for a visual range of a virtual camera that describes a distance of a plurality of points of the geometrical projection surface from the virtual camera in the virtual space; calculating an image from the virtual camera that images the geometrical projection surface in the virtual space; ascertaining, based on the depth map, a particular region of the image from the virtual camera in which the geometrical projection surface lies in a certain distance range in relation to the virtual camera; and Gaussian blurring of the image from the virtual camera in the region in which the particular region is imaged.
1. A method for displaying a vehicle environment of a vehicle, comprising:
detecting the vehicle environment in camera images with the aid of a plurality of cameras;
projecting the camera images onto a geometrical projection surface in a virtual space;
creating a depth map for a visual range of a virtual camera that describes a distance of a plurality of points of the geometrical projection surface from the virtual camera in the virtual space;
calculating an image from the virtual camera that images the geometrical projection surface in the virtual space;
ascertaining, on the basis of the depth map, a particular region of the image of the virtual camera in which the geometrical projection surface lies in a specific distance range in relation to the virtual camera; and
Gaussian blurring the image of the virtual camera in the region in which the particular region is imaged.
2. The method as recited in claim 1 , wherein the geometrical projection surface is modeled on the basis of the vehicle environment.
3. The method as recited in claim 1 , wherein the specific distance range is a range that extends outside a minimum distance in relation to the virtual camera.
4. The method as recited in claim 1 , wherein
a virtual model of the vehicle is located in the virtual space; and
the depth map is set up in such a way that for those regions of the image from the virtual camera in which the virtual model of the vehicle is detected, the depth map describes a distance of the points of the virtual model of the vehicle imaged therein from the virtual camera.
5. The method as recited in claim 1 , further comprising:
orienting the virtual camera to a particular point of interest in the virtual space.
6. The method as recited in claim 5 , wherein the particular point of interest is a point at which the vehicle is approaching an object.
7. A device for displaying a vehicle environment of a vehicle, the device designed to:
detect the vehicle environment in camera images with the aid of a plurality of cameras;
project the camera images onto a geometrical projection surface in a virtual space;
create a depth map for a visual range of a virtual camera that describes a distance of a plurality of points of the geometrical projection surface from the virtual camera in the virtual space;
calculate an image from the virtual camera that images the geometrical projection surface in the virtual space;
ascertain, on the basis of the depth map, a particular region of the image of the virtual camera in which the geometrical projection surface lies in a specific distance range in relation to the virtual camera; and
Gaussian blur the image of the virtual camera in the region in which the particular region is imaged.
