Abstract: A depth detection device includes a stereo image recording device, a scaler and a depth determiner is provided. The stereo image recording device is configured to record a stereo image of a scene, and includes a first optical path for recording a first image of the stereo image, and a second optical path for recording a second image of the stereo image. The first optical path and the second optical path have different lengths. The scaler determines a scaling of the first image or of the second image, by minimizing differing lateral magnification of objects in the scene, and for performing the scaling. The depth determiner determines a depth map of the scene based upon the scaled stereo image.
