ing at the problem that the 3D information captured by a light field camera can only provide a very narrow parallax when it is displayed, the recording process of information by the light field camera is analyzed, and a full-parallax 3D display method is proposed which converts the original light field data into an element image array (EIA) and resamples the objects in EIA to adjust the depth. In order to verify the validity of this method, the real 3D object is captured by the light field camera and displayed in the depth priority integral imaging (DPII) system after processing the light field image with the proposed method. The experimental results show that the full-parallax 3D display of light field data can be realized by the proposed method.
