In order to improve the recording speed of computer generated integral imaging, a rapid computer generated integral imaging method was proposed based on the theory of one-step pickup without pseudoscopic problem. In the one-step pickup process, the object point near the micro-lens array was ignored, the object point far from the micro-lens array was recorded, and the orthoscopic elemental image array was obtained. In the experiment, Direct3D software was used to pick up the 3D scene built up by 3Dsmax software using the proposed method, and an elemental image array was obtained very fast. The experimental results demonstrated that the recording time is only 0.56 second, fast recording speed is achieved, and a real and orthoscopic 3D scene is reconstructed.
