Pickup method adopting the modified algorithm to generate the elemental image from virtual objects is proposed to obtain the elemental image for real objects. In the proposed method, the number of capturing processes is reduced compared with the conventional multiple capturing method. The pseudoscopic image problem can be resolved by controlling the position and the direction of the imaging device in the proposed pickup system. The telecentric lens system is used to capture the orthographic scenes, which are divided and compounded into the elemental image. The validity of the proposal is proved by the experimental results of the pickup and the reconstruction.
An elemental image of the pre-distortion image in the off-axis integral floating system using a concave mirror is
generated. The concave mirror can be adopted as the floating device to improve the optical efficiency. The image
deformation due to the tilting axis of the concave mirror is analyzed to generate the pre-distortion image process. In this
paper, we calculate the image deformation in the off-axis structure of the concave mirror using the geometrical optics.
Using the simulation, the pre-distortion image is generated to compensate the 3D image. And the elemental image is
generated for the pre-distortion integrated image, which can be projected to the floating 3D image to resolve the image
deformation. The experiments of the off-axis integral floating are presented to prove and verify the proposal.
