提出了一种消除雾气对车载摄录设备光学成像影响的系统,改善了车载设备获取图像的视觉效果,优化了后续对图像中信息的提取与应用。设计的双模式雾气消散系统包括硬件和软件两部分,硬件为基于物理热消散效应的机械去雾结构,软件为基于大气散射模型估算的图像处理算法。能在不同湿度下保证车载摄录图像的清晰度和细节特征,具有实时处理和自适应反馈等优势,满足商业化应用需求。

This paper proposes a system for eliminating the influence of fog on optical imaging of vehicle recording equipment, the visual effect of the image acquisition by the vehicle-mounted equipment is improved, and the subsequent extraction and application of information in the image can be optimized. The designed dual-mode mist dissipating system includes two parts: hardware and software, the hardware is a mechanical defogging structure based on the physical heat dissipation effect and the software is an image processing algorithm based on the atmospheric scattering model estimation. It can better ensure the clarity and details of the vehicle recorded image under different humidity conditions, and has the advantages of real-time processing and adaptive feedback, which make it suitable for commercial applications.
