Abstract

Bright glare in nighttime situations strongly decreases human contrast perception. Nighttime simulations therefore require a way to realistically depict contrast perception of the user. Due to the limited luminance of popular as well as specialized high-dynamic range displays, physical adaptation of the human eye cannot yet be replicated in a physically correct manner in a simulation environment. To overcome this limitation, we propose a method to emulate the adaptation in nighttime glare situations using a perception-based model. We implemented a postprocessing tone mapping algorithm that simulates the corresponding contrast reduction effect for a night-driving simulation with glares from oncoming vehicles headlights. During glare, tone mapping reduces image contrast in accordance with the incident veiling luminance. As the glare expires, the contrast starts to normalize smoothly over time. The conversion of glare parameters and elapsed time into image contrast during the readaptation phase is based on extensive user studies carried out first in a controlled laboratory setup. Additional user studies have then been conducted in field tests to ensure validity of the derived time-dependent tone-mapping function and to verify transferability onto real-world traffic scenarios.

模拟传统显示器在夜间眩光情况下的视觉对比度降低
夜间明亮的眩光会严重降低人的对比度感知能力。因此,夜间模拟需要一种方法来真实地描绘用户的对比感知。由于流行的以及专门的高动态范围显示器的亮度有限,人眼的物理适应还不能在模拟环境中以物理正确的方式复制。为了克服这一限制,我们提出了一种使用基于感知的模型来模拟夜间眩光情况下的适应方法。我们实现了一种后处理色调映射算法,该算法模拟了夜间驾驶模拟中迎面而来的车辆前灯眩光的相应对比度降低效果。在眩光中,色调映射根据入射遮挡亮度降低图像对比度。随着眩光的消失,对比度开始随着时间的推移平稳地正常化。在重新适应阶段将眩光参数和经过的时间转换为图像对比度是基于首先在受控实验室设置中进行的广泛用户研究。然后在实地测试中进行了更多的用户研究,以确保推导出的随时间变化的音调映射功能的有效性,并验证可转移到实际交通情景的情况。

期刊介绍: ACM Transactions on Applied Perception (TAP) aims to strengthen the synergy between computer science and psychology/perception by publishing top quality papers that help to unify research in these fields. The journal publishes inter-disciplinary research of significant and lasting value in any topic area that spans both Computer Science and Perceptual Psychology. All papers must incorporate both perceptual and computer science components.
