Patent Images

1. An image processing device comprising:

  • an image acquisition portion which acquires an input image based on a result of shooting by a camera shooting surroundings of a vehicle;

    an image transformation portion which generates a transformed image from the input image by coordinate transformation such that a position of a characteristic point on the input image is transformed into a position of a reference point on the transformed image;

    a parameter storage portion which stores an image transformation parameter that is based on the position of the characteristic point and the position of the reference point and used for transforming the input image into the transformed image;

    a loss detection portion which checks, by use of the image transformation parameter stored in the parameter storage portion, whether or not, within an entire region of the transformed image obtained from the input image, an image-missing region is present where no image data based on image data of the input image is available; and

    a parameter adjustment portion which, if the image-missing region is judged to be present within the entire region of the transformed image, adjusts the image transformation parameter via changing the position of the reference point so as to suppress presence of the image-missing region.
