Panoramic View System for a Vehicle

DRIVE April 9, 2020

A panoramic view system for a vehicle includes at least one real camera () for capturing an image of the surroundings of the vehicle from non-centered position, a virtual camera (), an image processing unit, and a display unit which is configured to represent, in a projected manner, the image captured by the real camera () and at least one geometric form ( to ) as an overlay over the captured image. The image processing unit is configured to project the captured image onto a first plane () perpendicular to the real camera () such that perspective distortions in the captured image resulting from the non-centered position of the real camera () are distortion-corrected, and to project the at least one geometric form ( to ) onto a second plane () perpendicular to the virtual camera () such that the at least one geometric form ( to ) is represented in an undistorted manner on the display unit (). The image processing unit is configured to find an affine transformation (T) between the first plane () and the second plane () by a delta transformation between the real camera () and the virtual camera (), and to apply the affine transformation (T) to the first plane () which contains the projected and distortion-corrected captured image (′) such that a modified representation (″) of the distortion-corrected captured image (′) is aligned with the at least one undistorted geometric form ( to ) in the second plane ().
