Title:
【発明の名称】キー物体の整合状態を直接モニターする立体写真プリンターおよび立体写真プリント方法
Document Type and Number:
Japanese Patent JP3326435
Kind Code:
B2
Abstract:
A 3D printer and method which uses a beamsplitter or a mirror to form a reflected image which is a mirror image of the actual image exposed on the print material. A CCD detector array is placed on the reflected image plane to monitor the key-subject registration. The beamsplitter or mirror is physically linked to the print material cassette so that the CCD detector array shares the same projected image that is exposed on the print material regardless of the printing position. With such an approach, the CCD detector array can directly detect any off-alignment due to mechanical errors or distortion/aberration by the projection lens.
