Filmless method and apparatus for producing 3-D photographs

摘要

A filmless 3D printing method for producing 3D photographs on lenticular print material. The 3D photograph is composed of a series of 2D images of a scene acquired by a video camera and displayed on a video monitor screen. During printing, the projection lens and the print material are moved to different positions to change the projection angles and fill the lenticules with compressed images. While the video camera is moved in relation to the scene to acquire 2D images, it aims at the key subject of the scene at all times so that the location of key subject image on the images displayed on the screen is always the same. Thus, the 2D images exposed on the print material are automatically aligned. The 2D images of a scene at different viewing angles can also be generated on a computer.
