Video monitoring system for a motor vehicle

1. A method for providing an image using a camera monitor system for a motor vehicle with a trailer, wherein the camera monitor system has a rear camera assigned to a rear side of the trailer, a side camera assigned to a longitudinal side of the motor vehicle, and a monitor for presenting images of the cameras, the method comprising:

capturing a first image with the rear camera;

capturing a second image with the side camera;

constructing a composite image comprising the first image and the second image based at least in part on an ascertained trajectory of the motor vehicle; and

displaying the composite image on the monitor;

ascertaining a specified image content in the first image and in the second image, wherein the specified image content includes multiple side lamps of the trailer and the side lamps are driven in a specified blinking pattern to identify each respective side lamp; and

ascertaining a position of the rear camera relative to the side camera based on the ascertained image content;

wherein the monitor comprises a replacement for a left conventional exterior mirror, the monitor disposed in a cabin of the motor vehicle in front of and to the left of a driver seated in a driver's seat of the motor vehicle;

wherein the side camera comprises a removable camera.

2. The method as claimed in claim 1 , wherein ascertaining the overall image comprises combining the first image and the second image by stitching.

3. The method as claimed in claim 1 , wherein ascertaining the overall image comprises combining the first image and the second image to provide a total field of view in the overall image composed of a first field of view of the first camera and a second field of view of the second camera.

4. The method as claimed in claim 1 , wherein ascertaining the overall image comprises combining the first image and the second image to provide a total field of view composed of a first field of view of the first camera and a partial region of a second field of view of the second camera.

5. The method as claimed in claim 1 , wherein ascertaining the image content further comprises ascertaining side edges of the trailer in the first image and the second image.

6. The method as claimed in claim 1 , wherein the camera monitor system comprises two rear cameras assigned to the rear side of the vehicle;

the method further comprising:

ascertaining a specified image content in the respective image in each of the two rear cameras, and

ascertaining a position of the two rear cameras relative to one another and/or relative to the second camera based on the ascertained image content.

7. A camera monitor system for a motor vehicle with a trailer, the camera monitor system comprising:

a rear camera assigned to a rear side of the trailer;

a side camera assigned to a longitudinal side of the motor vehicle;

a monitor for presenting images of the first camera and the second camera; and

a processor programmed to:

capture a first image with the rear camera;

capture a second image with the side camera;

ascertain a specified image content in the first image and in the second image, wherein the specified image content includes multiple side lamps of the trailer and the side lamps are driven in a specified blinking pattern to identify each respective side lamp; and

ascertain a position of the rear camera relative to the side camera based on the ascertained image content;

construct a composite image comprising the first image and the second image based at least in part on an ascertained trajectory of the motor vehicle; and

display the composite image on the monitor;

wherein the monitor comprises a replacement for a left conventional exterior mirror, the monitor disposed in a cabin of the motor vehicle in front of and to the left of a driver seated in a driver's seat of the motor vehicle;

wherein the side camera comprises a removable camera.

8. The camera monitor system as claimed in claim 7 , wherein the rear camera comprises a removable camera.
