1. A vehicle vision system comprising:
- a plurality of Ultra Wide-Angle (UWA) lens cameras mounted on a plurality of sides of a vehicle, each camera providing a corresponding UWA feed, wherein each camera comprises a Geometry and Color Processing (GCP) unit that is configured to pre-process the corresponding UWA feed, by applying a plurality of geometry and color transformations to the corresponding UWA feed in preparation for a seamless surround-view image construction;
a central logic configured to combine the pre-processed plurality of UWA feeds provided by the corresponding plurality of cameras, and output a surround-view image of the vehicle; and
at least one display unit to display at least one of the surround-view output image, one or more of the UWA feeds, and one or more of the pre-processed UWA feeds;
wherein the GCP pre-processing of a UWA feed comprises selecting a viewing perspective in the corresponding UWA feed according to a display mode instruction, and applying a perspective distortion correction transformation to the selected viewing perspective.

Abstract
Vehicle visual systems are disclosed to produce seamless and uniform surround-view images of the vehicle using a number of Ultra Wide-Angle (UWA) lens cameras and optionally HUD systems. A distributive system architecture wherein individual cameras are capable of performing various image transformations allows a flexible and resource efficient image processing scheme.

16. A method for producing a surround-view image of a vehicle, said method comprising:
-
capturing a plurality of Ultra Wide-Angle (UWA) feeds by a corresponding plurality of UWA lens cameras mounted on sides of the vehicle, wherein each camera comprises a Geometry and Color Processing (GCP) unit; pre-processing the plurality of Ultra Wide-Angle (UWA) feeds in preparation for a seamless surround-view image, comprising applying a plurality of geometry and color transformations by the plurality of the cameras'"'"' GCP unit to the corresponding UWA feed; combining the pre-processed plurality of UWA feeds provided by the corresponding plurality of cameras, using a central logic to output the surround-view image of the vehicle; and displaying at least one of the surround-view output image, one or more of the UWA feeds, and one or more of the pre-processed UWA feeds; wherein the GCP pre-processing of a UWA feed comprises selecting a viewing perspective in the corresponding UWA feed according to a display mode instruction, and applying a perspective distortion correction transformation to the selected viewing perspective. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
