A vehicle with polarization metric image normalization logic is provided. A system for a host vehicle operating on a road surface includes a polarization metric camera, a global positioning system ("GPS") receiver, a compass, and an electronic control unit ("ECU"). A camera collects polarization metric image data of a driving scene, including potential driving paths on a road surface. The ECU receives the polarization metric image data, estimates a sun position using a GPS receiver and a compass, and calculates an ideal representation of the road surface using the sun position. The ECU normalizes the polarization metric image data such that the road surface has a normalized representation in the driving scene, i.e., a linear polarization angle ("AoLP") and a degree of linear polarization ("DoLP") are equal to predetermined fixed values. The ECU performs a control action using the normalized representation.

    提供了具有偏振度量图像归一化逻辑的车辆。一种用于在道路表面上操作的主车辆的系统包括:偏振度量相机、全球定位系统(“GPS”)接收器、罗盘和电子控制单元(“ECU”)。相机收集驾驶场景的偏振度量图像数据,包括道路表面上的潜在驾驶路径。ECU接收偏振度量图像数据,使用GPS接收器和罗盘估计太阳位置,并使用太阳位置计算道路表面的理想表示。ECU将偏振度量图像数据归一化,使得道路表面在驾驶场景中具有归一化表示,即,线性偏振角(“AoLP”)和线性偏振度(“DoLP”)等于预定固定值。ECU使用归一化表示执行控制动作。
