In 3D light-field display, perspective error occurs when the viewer moves forward or backward, resulting in the perception of incorrectly deformed 3D images. A perspective correction method based on optical flow prediction is presented to achieve correct perspective in 3D light-field display. A perspective relationship completion network is presented, which integrates an optical flow prediction network and a perspective transformation network, to achieve effective correction of perspective relations. The optical flow prediction network supplies depth information to assist the perspective transformation network in generating correct depth-oriented optical flow. The vertical component of the depth-oriented optical flow is retained to interpolate perspective information at any distance within the specified range. The viewer’s position is captured using an eye-tracking device, enabling real-time generation and encoding of images that are loaded on the 3D light-field display system for immediate perspective correction. Experimental results demonstrate the method can effectively correct perspective relations and present correct 3D images when the viewer moves forward or backward.
