为了优化主动快门式立体显示中的闪烁现象,对环境光的影响进行了深入的研究。研究中使用高采样率瞬态亮度响应测量系统对透过快门眼镜的环境光信号进行实时测量和记录,测量的时域信号经过傅里叶变换后得到对应的频域信号,用来分析环境光影响闪烁的可能原因。同时,基于多参数可调的发光二极管(LED)照明系统完成了两组视觉感知实验,结果表明,环境光的频率、最大光强、占空比以及显示器的显示内容等参数对人眼透过快门眼镜感受到的环境光闪烁程度有显著性的影响,120Hz或以上的倍频光作为匹配环境光可以消除环境光闪烁并且达到比较好的舒适度。研究结果对主动快门式立体显示中闪烁感的优化以及视觉舒适度的提高具有指导和推动作用。
In order to optimize the flickering in the active shutter stereoscopic display, the influence of the ambient light is deeply studied. In the study, the high-sampling-rate transient brightness response measurement system was used to measure and record the ambient light signals passing through the shutter glasses in real time. The measured time-domain signals were Fourier transformed to obtain the corresponding frequency-domain signals for analyzing ambient light The possible causes of the flicker. At the same time, two groups of visual perception experiments based on multi-parameter adjustable LED lighting system were completed. The results showed that the parameters such as ambient light frequency, maximum light intensity, duty ratio and the display content of the display are transparent to human eyes Shutter glasses feel the degree of ambient light flashing has a significant impact, 120Hz or more frequency light as a matching ambient light to eliminate ambient light flashing and achieve better comfort. The results of the study proactively promote the optimization of flicker and the improvement of visual comfort in active shutter stereoscopic display.
