Passive ground-based remote sensing of radiation fog

Heather Guy et al.

Summary: Accurate boundary layer temperature and humidity profiles are crucial for successful fog forecasting, while precise retrievals of liquid water path aid in understanding the climatological significance of fog. Passive ground-based remote sensing systems like infrared spectrometers have the potential to support operational forecasting by retrieving thermodynamic profiles and liquid water path effectively.

Multi-View Optical Image Fusion and Reconstruction for Defogging without a Prior In-Plane

Yuru Huang et al.

Summary: This study presents a technique for fusion and reconstruction of multi-view images taken in fog by two cameras fixed on a moving platform, using a close visible object as a reference for camera calibration. The positions and aiming directions of the cameras are determined based on this reference, allowing for accurate image fusion beyond visibility.

Visibility Enhancement and Fog Detection: Solutions Presented in Recent Scientific Papers with Potential for Application to Mobile Systems

Razvan-Catalin Miclea et al.

Summary: Environmental factors such as fog, rain, snow, haze, and sun glare can pose significant dangers to drivers in mobile systems. These phenomena decrease visibility and present challenges for drivers in terms of speed selection. Researchers have proposed various solutions and methods in the past decade to estimate or improve visibility in adverse weather conditions, with a particular focus on the dangerous fog phenomenon.
