Techniques are described for identifying pixel locations using a transformation function. A transformation function is identified based on the projection space of a 2D representation, and pixel locations are generated using the transformation function.

A vehicle vision system includes a camera configured to be positioned on a vehicle and a processing system operatively coupled to the camera. The processing system is operable to process image data captured by the camera. The image data is representative of a scene viewed by the camera. The processing system may further generate an image having three image panes including a central image pane derived from a first subset of captured image data and two side image panes derived from second and third subsets of captured image data. Each of the side image panes are shaped as parallelograms and arranged with respect to the central image pane to appear folded with respect to the central image pane. The processing system can output the image to a display for viewing by a driver of the vehicle.

A method, a head-up display and a display system for the perspective transformation and displaying of rendered image content, as well as a corresponding vehicle, are provided. In the perspective transformation and outputting method, the image content to be displayed is subdivided into a plurality of tiles, and the individual tiles are each transformed in perspective using perspective transformation. The individual tiles that have been transformed in perspective are then combined to form a transformed image content, and the image content transformed in perspective is projected onto a projection area of the head-up display or displayed on a display unit.

The invention relates to a method for producing images of a stored three-dimensional model (30) of the surroundings of a vehicle (20), said images having been corrected for perspective. A camera picture (32) is produced by a camera device (21) of the vehicle, and the produced camera picture (32) is projected onto a projection surface (31) in the surroundings model. A region (33) relevant for driving is marked in said stored three-dimensional surroundings model (30), and this marked region (33) is projected onto a corresponding projection surface area (35) of the projection surface (31). An image of the projection surface (31) with the region (33) projected onto the projection surface area (35) is produced and output by means of a virtual camera (72) that can move freely in the surroundings model (30).
