Key-subject alignment method and printer for 3d printing uti lizing a video monitor for exposure

摘要

A 3D printer for producing 3D photographs on lenticular print material in which a video monitor is used to display stored digital 2D images of different views of a scene for exposure. Prior to printing, one of the stored 2D image is displayed on a viewing monitor and the key subject image of the displayed 2D image is selected. Based on the location of the selected key subject image, the computer searches for the key subject location of each of the other stored 2D images and electronically shifts the 2D images so that the key subject location of all different views is the same. During printing, the electronically shifted 2D images are sequentially displayed on the video monitor and projected through a projection lens onto the lenticular screen at different projection angles.
