Abstract
A system for capturing and displaying not directly-viewable spaces near a vehicle includes an apparatus for image capturing and an apparatus for image display. The apparatus for image capturing captures at least two arbitrary points Q and R. A ground plane is spanned by the Cartesian coordinates xv and yv, and xv lies in the vehicle middle plane. The display displays an image that includes an image Q′ of the point Q and an image R′ of the point R on a display plane spanned by the Cartesian coordinates xv′ and yv′, with xv′ lying on a reproduction of the vehicle middle plane. A projection QR, xv of the vector QR onto xv and a projection Q′R′, xv′ of a vector Q′R′ onto xv′ have the same direction, and a projection QR, yv of the vector QR onto yv and a projection Q′R′, yv′ of a vector Q′R′ onto yv′ have the same direction.
