Patent Images

1. A panoramic imaging system comprising:

  • an image acquisition means for acquiring a wide-angle image using a wide-angle imaging lens rotationally symmetric about an optical axis;

    an image processing means for generating a panoramic image based on the said wide-angle image; and

    an image display means for displaying the said panoramic image on a rectangular screen,wherein;

    a coordinate of an image point on the rectangular screen corresponding to an object point having a coordinate (X, Y, Z) in a world coordinate system, which has a nodal point of the wide-angle lens as an origin and a vertical line passing through the origin as the Y-axis and an intersection line between a reference plane containing the said Y-axis and the said optical axis of the lens and a horizontal plane perpendicular to the said vertical line as the Z-axis, is given as (x″

    , y″

    ),a horizontal incidence angle ψ

    , which an incident ray originating from the said object point makes with the said reference plane, is given as
