Imaging delivering to correct retina assisted with tracking technique is a common practice for autostereoscopic displays with stereo two‐view data format. Due to various latencies produced in camera buffering, computer processing, data transmission, and illumination refreshing, delayed image delivery will give rise to a substantial degradation of the 3D display experience. This is particularly obvious for directional backlight 3D displays where significant flickering is resulted as a result of the inherent latency. This work systematically analyzes the source of latency by quantitatively measuring the exact latency value in a typical directional backlight autostereoscopic display. Based on accurate measurement, a motion prediction solution is proposed to improve the synchronization between the backlight illumination and viewer's eye location. Motion prediction helps overcome the lag between the center of illumination and viewer's eye, providing a flicker‐free viewing experience for both a stationary and a moving viewer.

通过定向自动立体显示器中的运动预测克服延迟

具有跟踪双眼数据格式的自动立体显示器的常见做法是借助跟踪技术将图像传送到正确的视网膜。由于在相机缓冲，计算机处理，数据传输和照明刷新中产生各种延迟，延迟的图像传递将导致3D显示体验的大幅下降。这对于定向背光3D显示器尤其明显，因为固有延迟会导致明显的闪烁。这项工作通过定量测量典型定向背光自动立体显示器中的确切延迟值来系统地分析延迟源。基于准确的测量，提出了一种运动预测解决方案，以改善背光照明和观看者眼睛位置之间的同步。
