为了更准确、客观地评价快门眼镜式立体显示技术中的闪烁现象,提出了一种基于时变光信号测量的闪烁程度客观评价方法。利用瞬态亮度响应测量系统实现对显示器时变亮度信号的准确记录,然后在阴极射线管(CRT)显示的临界闪烁频率(CFF)估计模型基础上,结合基于快门眼镜式立体显示的视觉感知实验,建立了快门眼镜式立体显示的闪烁程度估计模型。估计模型的估算结果与视觉感知实验结果的相关系数达到0.97。该瞬态亮度测量系统以及提出的闪烁程度估计模型实现了对快门眼镜式立体显示闪烁程度的客观量化,同时对视觉舒适度的优化也起到了积极的推动作用。
In order to more accurately and objectively evaluate the flicker phenomenon in the shutter glasses stereoscopic display technology, an objective evaluation method based on the time varying optical signal measurement is proposed. Based on the transient flicker frequency (CFF) estimation model of cathode ray tube (CRT), combined with the visual perception experiment based on the shutter glass stereo display, the transient brightness response measurement system is used to accurately record the time varying brightness signal of the display. , A blinking degree estimation model of shutter glasses stereoscopic display is established. The correlation coefficient between the estimated results of the estimation model and the results of the visual perception experiments reaches 0.97. The transient brightness measurement system and the proposed scintillation level estimation model can objectively quantify the degree of blinking of the shutter glass stereoscopic display and also play an active role in optimizing the visual comfort.
