我们提出了一个飞行时间测量算法的深度和强度，是强大的雾。该算法的核心思想是通过多个时间门控和分配一个时间门控曝光量来估计雾的散射特性，从而补偿雾的散射效应。一旦估计了属性，就可以通过基于物理的模型从其余曝光中重建深度和强度。人工雾实验表明，该方法可以测量雾的深度和强度，而不考虑雾的特性。我们还通过室外实验证实了我们的方法在真实的雾中的有效性。(C)根据OSA开放获取出版协议的条款，2021年美国光学学会
We propose a time-of-flight measurement algorithm for depth and intensity that is robust to fog. The key idea of the algorithm is to compensate for the scattering effects of fog by using multiple time-gating and assigning one time-gated exposure for scattering property estimation. Once the property is estimated, the depth and intensity can be reconstructed from the rest of the exposures via a physics-based model. Several experiments with artificial fog show that our method can measure depth and intensity irrespective of the traits of the fog. We also confirm the effectiveness of our method in real fog through an outdoor experiment. (C) 2021 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
