Abstract

The invention relates to a method and a device for monitoring an external dimension of a vehicle, particularly of a change in the external dimension due to an external vehicle load.

Claims

1. A method of monitoring an external dimension of a vehicle, comprising steps:

with at least one camera arranged on the vehicle, imaging a region of the vehicle and producing image data,

processing the image data with respect to an external vehicle load, and,

monitoring the external dimension of the vehicle depending on the processing of the image data.

2. The method according to claim 1, wherein the monitoring of the external dimension comprises determining whether there is a change in the external dimension of the vehicle.

3. The method according to claim 1, wherein the monitoring of the external dimension comprises determining a size of the external dimension.

4. The method according to claim 1, wherein the at least one camera covers the region of the vehicle in which the external vehicle load may be arranged.

5. The method according to claim 1, wherein the processing of the image data comprises searching for characteristic features of external vehicle loads in the image data.

6. The method according to claim 1, wherein the processing of the image data comprises searching by an optical-flow method, for image segments in the image data in which there is motion.

7. The method according to claim 1, wherein the at least one camera covers the region of the vehicle and/or a region surrounding the vehicle in which a shadow of the external vehicle load may be detectable.

8. The method according to claim 1, wherein the processing of the image data comprises searching for a shadow of the external vehicle load.

9. The method according to claim 1, wherein the monitoring of the external dimension is performed depending on a known installation position and orientation of the at least one camera.

10. A device for monitoring an external dimension of a vehicle, comprising

at least one camera that is arranged on the vehicle and configured to acquire image data from a region of the vehicle,

first means for processing the image data with respect to an external vehicle load, and

second means for monitoring the external vehicle dimension depending on the processing of the image data.
