    摘要: A heads up display (HUD) is provided. The HUD includes a projector configured to project a distorted representation of image data onto a non-planar surface. The HUD also includes warp image circuitry configured to store offsets to be applied to the image data to generate the distorted representation. The offsets represent respective distances for moving coordinates of a portion of pixels within the image data and the offsets are stored within a memory region of the warp image circuitry. The portion of pixels corresponds to vertices of polygons. The warp image circuitry is further configured to map the vertices of polygons to the non-planar surface. A method for projecting an image onto a warped surface is also provided.

    摘要: A vehicle having a heads up display (HUD) system is provided. The HUD system includes an image rendering device configured to provide a distorted representation of image data to a non-planar surface within a field of view of an occupant of the vehicle. Warp image circuitry configured to store offsets to be applied to the image data to generate the distorted representation provided to the image rendering device is included in the HUD system. The offsets represent respective distances for moving coordinates of a portion of pixels within the image data and the offsets are stored within a memory region of the warp image circuitry. The portion of pixels correspond to vertices of polygons. The offsets are derived through calibration data provided to the warp image circuitry. The calibration data is selected from one of a plurality of view positions for the occupant.
