1. A device for detecting at least one of an object and a person, comprising: a stereo-sensitive image recording unit including at least two image sensors; an evaluation unit to evaluate signals supplied by the at least two image sensors; a carrier to arrange the at least two image sensors on; a carrier drive device to drive the carrier, wherein the carrier is rotatable via the carrier drive device; and a drive device assigned to each of the at least two image sensors, wherein the device is operable to detect the at least one of the object and the person in a surrounding vehicle, wherein the optical axes are aligned in a changed manner with respect to at least one of a vehicle longitudinal axis, a vehicle transverse axis, and a vehicle vertical axis; wherein optical axes of the at least two image sensors are changed relative to each other during operation of the at least two image sensors, so that an overlapping region of recording regions of the at least two image sensors is one of enlarged and reduced, respectively, corresponding to a change of the optical axes, wherein for two images taken from different viewing angles, corresponding to a distance from each other of the at least two image sensors, the evaluation unit searches corresponding image regions in the two images taken from the different viewing angles, wherein the evaluation unit generates where these corresponding image regions lie based on settings of the at least two image sensors, and wherein the evaluation unit, using the corresponding image positions, determines exact locations of the corresponding regions in the two images by using a searching method for estimating a displacement, and wherein based on the corresponding image regions, the evaluation unit determines a relative orientation of the at least two image sensors by determining an essential matrix E by a suitable solution of the equation system, ( x 1 y 1 1 ) T ⁢ E ⁡ ( x 2 y 2 1 ) = 0 the 3×3 matrix satisfying the conditions of an essential matrix, and x and v forming the appropriate coordinates in the image of right and left one of the at least two image sensors, respectively, wherein a conditional equation for each corresponding pair of points is obtained.
