基于LED屏的立体图像生成方法

A stereoimage synthesizing method based on LED panel

LED屏自由立体显示系统是将光栅板附在LED显示屏的外表面,根据LED屏的参数生成立体图像文件。其生成方法包括三个步骤,首先根据LED屏和光栅板的特征参数计算出合成立体图像文件所需的像素点映射表;然后采用缝隙删除技术对视点图像进行处理,使其满足像素点映射表的要求;最后,将经处理的视点图像合成立体图像。实验结果表明,提出的方法适用范围广,并能快速高效地合成任意视点数的立体图像,获得较好的立体视觉效果。

Based on the optical characteristic of optical-plate and the structural characteristic of LED panel,a stereoimage synthesizing method based on LED panel had three steps:First,a pixel mapping which was used to synthesize the 3D image was calculated according to the parameters of LED panel and optical-plate.Secondly,multi-view images were processed by seam-carving based on the demand of the derived pixel mapping.At last,the 3D image was synthesized from the processed multi-view images.Experimental results show that the method,which gets better 3D visual,can be applied to any LED autostereoscopic displays,and can synthesize the 3D image of arbitrary viewpoints quickly and efficiently.
