提出了一种基于摄像机的公路隧道照明测量仪。该系统的目的是估计面纱亮度，因为它将被接近隧道的司机所感知，从而允许估计隧道入口的最佳亮度水平，从而提高司机的安全性。所提出的测量仪器和相对校准方法分别基于低成本的商业级相机和参考标准。
A camera-based measuring instrument for road tunnels lighting is proposed. The system is aimed at estimating the veiling luminance as it will be perceived by a driver approaching the tunnel, thus allowing the estimation of the optimum luminance level of tunnel entrances, hence increasing the driver's safety. The proposed measuring instrument and the relative calibration method are based on a low-cost commercial grade camera and a reference standard, respectively.
