Abstract
A method for activating a driver assistance system using a stereo camera system including a first and a second camera, the method including reading in, a first image from the first camera and a second image from the second camera being read in. The method furthermore includes forming, a cost function being created using the first and second images. Furthermore, in a further method step of determining, a periodicity parameter representing a periodic structure of an object to the stereo camera system is determined, using at least one local minimum of the cost function. Finally, the method includes using, the periodicity parameter being used to activate the driver assistance system.

A method for activating a driver assistance system using a stereo camera system including a first camera and a second camera, the method comprising:
- reading in a first image from the first camera and a second image from the second camera;
- forming a cost function, using the first image and the second image;
- determining a periodicity parameter representing a periodic structure of an object, at least using a local minimum of the cost function;
- and
- using the periodicity parameter for activating the driver assistance system.
A device, which is configured to activate a driver assistance system using a stereo camera system including a first camera and a second camera, the device configured to:
- read in a first image from the first camera and a second image from the second camera;
- form a cost function, using the first image and the second image;
- determine a periodicity parameter representing a periodic structure of an object, at least using a local minimum of the cost function;
- and
- use the periodicity parameter for activating the driver assistance system.
A non-transitory machine-readable storage medium on which is stored a computer program for activating a driver assistance system using a stereo camera system including a first camera and a second camera, the computer program, when executed by a computer, causing the computer to perform:
- reading in a first image from the first camera and a second image from the second camera;
- forming a cost function, using the first image and the second image;
- determining a periodicity parameter representing a periodic structure of an object, at least using a local minimum of the cost function;
- and
- using the periodicity parameter for activating the driver assistance system.
