Abstract

A method for operating a camera-monitor system for a motor vehicle, in which the camera-monitor system has two cameras which are assigned to a common side of the motor vehicle and are both designed to provide an image of the surroundings of the motor vehicle, wherein the imaged surroundings of the images partially overlap. The system ascertains transformation parameters for transforming a second image of the second camera such that an image element in a peripheral region of a transformed second image connects to a corresponding image element in a peripheral region of a first image of the first camera. Further, ascertaining transformation parameters for transforming the second image in dependence on the ascertained transformation parameters and in dependence on a specification provided for the transformed second image. The system transforms the second image with the further transformation parameters into the transformed second image.

Claims16

Dependent claims

A method for operating a camera-monitor system for a motor vehicle comprising:

providing a first image of surroundings of the motor vehicle from a first camera;
providing a second image of surroundings of the motor vehicle from a second camera, wherein the imaged surroundings partially overlap in the first and second images;
ascertaining transformation parameters for transforming a second image of the second camera such that an image element in a peripheral region of a transformed second image connects to a corresponding image element in a peripheral region of a first image of the first camera;
ascertaining further transformation parameters for transforming the second image in dependence on the ascertained transformation parameters and in dependence on a specification provided for the transformed second image;
and transforming the second image only once with the further transformation parameters into the transformed second image such that the provided specification and connection in edge areas are realized wherein the specification provided comprises at least one of:
representing a bottom edge of the motor vehicle so that it is straight, representing a line parallel to the bottom edge so that it is straight, and representing a specified section from the surroundings.

A camera-monitor system for a motor vehicle comprising:

a first camera to capture a first image of surroundings of the motor vehicle;
a second camera to capture a second image of surroundings of the motor vehicle, wherein the imaged surroundings partially overlap in the first and second images;
an electronic control unit connected to the first and second camera with instructions for:
ascertaining transformation parameters for transforming a second image of the second camera such that an image element in a peripheral region of a transformed second image connects to a corresponding image element in a peripheral region of a first image of the first camera;
ascertaining further transformation parameters for transforming the second image in dependence on the ascertained transformation parameters and in dependence on a specification provided for the transformed second image;
and transforming the second image only once with the further transformation parameters into the transformed second image such that the provided specification and connection in edge areas are realized wherein the specification provided comprises at least one of:
representing a bottom edge of the motor vehicle so that it is straight, representing a line parallel to the bottom edge so that it is straight, and representing a specified section from the surroundings.
