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.

Abstract: Systems and methods for calibrating an image projection system, using image capture devices are disclosed. In particular, Wide-Angle (WA) and Ultra Wide-Angle (UWA) lenses can be utilized to eliminate need for traditional test patterns and tedious alignment settings. That is particularly useful for automatic calibration of projection sources that may require frequent adjustments on the field. Geometric mapping techniques combined with image analytics allow identifying parallel lines in an image captured from a scene. Coordinates of vanishing points corresponding to pairs of parallel lines provide sufficient information to determine orientation of the image projection system in space.

Abstract: Various embodiments are described herein for a system and method for calibrating a display device to eliminate distortions due to various components such as one or more of lenses, mirrors, projection geometry, lateral chromatic aberration and color misalignment, and color and brightness non-uniformity. Calibration for distortions that vary over time is also addressed. Sensing devices coupled to processors can be used to sense display characteristics, which are then used to compute distortion data, and generate pre-compensating maps to correct for display distortions.
