Abstract
A method for detecting a vehicle position on a lane, including: reading in a first image of a first camera, having a first optical axis and reading in at least a second image of at least a second camera having a second optical axis, the cameras being oriented so that the first and second optical axis intersect outside of the detection angle of the first and/or second camera, the first and the at least second image each enclosing a viewing angle deviating by an angle of 90 degrees maximum from the driving direction. Determining at least one interlinked image gradient for each of the first image and the at least second image. Assigning the at least one interlinked image gradient to a boundary object and assigning the at least one additional interlinked image gradient to a boundary object and/or to one additional boundary object, and ascertaining a relative position of the vehicle as to the boundary object and/or to the additional boundary object to detect the vehicle position.
