Image correction method to compensate for image distortion point of view

摘要

A walk Attraction (4) comprising: a predetermined path (6) of the vehicle which extends through a building; a projection surface (12) adjacent the predetermined path (6) of the vehicle; a projector (14) arranged to project an image in stereoscopic 3D motion (13) on the projection surface (12); a vehicle (8) movable along the predetermined path (6) of the vehicle, the vehicle (8) having positions passengers to accommodate passengers (10) and wherein the vehicle (8) includes a base motion to generate a motion in slope, in circles, with a deviation, up and down, as undulatory and back and forth; and means for compensating the image in stereoscopic 3D motion (13) for image distortion viewpoint to viewpoint motion, the compensating means carrying out the steps of: a. determine a motion profile predetermined viewpoint moving the vehicle along the predetermined path (6) of the vehicle (8) of the park, the motion profile is a record of the time, position, velocity and the orientation of the vehicle (8) along the path (6) of the vehicle, the motion profile further including movements in slope, in circles, with a deviation, up and down, as undulatory and back and forward; b. a framework of view (34) on which it is to project an image (13); c. determine the temporal and spatial relationship between the viewpoint and moving the view frame (34) at each point along the moving viewpoint; d. obtaining a plurality of frame images of a perspective view from a viewpoint moving while traveling through the predetermined movement profile, the plurality of images comprising a dot matrix image of the view frame; and. transforming each of the plurality of images into a plurality of compensated images, said processing comprising the step of remapping the dot matrix image of the view frame (34) by using a transformation function that adjusts the plurality of images offset in the size of the view frame (34) as seen from a fixed perspective where the transformation function acts to compensate images in synchronization with the relative movement of the vehicle (8) and the projection surface (12) ; and f. projecting the plurality of images compensated on the projection surface (12) from the fixed point of view in synchronization with the motion profile to substantially reduce the distortion of the image of the viewpoint to thereby form the moving image 3D offset (13) on the projection surface (12) for display to the passengers (10) in the vehicle (8).
