Effects of pickup mode and parameters of integral imaging based on C4D

The pickup mode of 3D scene in integral imaging (II) consists of parallel pickup, convergent pickup and off-axis pickup. Combining the advantages of parallel pickup and convergent pickup, a method for off-axis pickup is proposed. In fact, the depth of field (DOF) of the II is not only affected by various parameters in the display process, but also seriously affected by pickup process. We deduce the parameters that affect the DOF during the pickup process through theoretical analysis. In the modeling software C4D (Cinema 4D) the experiment is carried out. The results show that off-axis method is better, and verify the correctness of the calculation formula of DOF from the pickup process.
