1. A method of compensating for point of view image distortion in 3D stereoscopic image projections for a moving point of view, the method comprising the steps of:

  • a. determining a motion profile of the moving point of view;

    b. establishing a frame of view onto which an image is to be projected;

    c. determining the temporal and spatial relationship between the moving point of view and the frame of view at each point along the moving point of view;

    d. obtaining a plurality of images of the frame of view from a perspective of a moving point of view while traveling through the motion profile, the plurality of images comprising an array of image points of the frame of view;

    e. transforming each of the plurality of images into a plurality of compensated images, said transformation comprising the step of re-mapping the array of image points of the frame of view using a transformation function that fits the plurality of compensated images into the size of the frame of view as observed from a stationary perspective point; and

    f. projecting the plurality of compensated images onto a projection surface from the stationary perspective point in synchronization with the moving profile to substantially reduce point of view image distortion.
