基于光流预测的三维光场显示透视关系校正
3D light-field display with corrected perspective based on optical flow prediction
摘要
Abstract
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.关键词
