Abstract: A method using Long Wave Infrared Imaging Polarimetry for improved mapping and perception of a roadway or path and for perceiving or detecting obstacles comprises recording raw image data using a polarimeter to obtain polarized images of the roadway or area. The images are then corrected for non-uniformity, optical distortion, and registration. IR and polarization data products are computed, and the resultant data products are converted to a multi-dimensional data set for exploitation. Contrast enhancement algorithms are applied to the multi-dimensional imagery to form enhanced object images. The enhanced object images may then be displayed to a user, and/or an annunciator may announce the presence of an object. Further, the vehicle may take evasive action based upon the presence of an object in the roadway.

Abstract translation: 一种使用长波红外成像旋光仪以改进道路或路径的映射和感知以及用于感知或检测障碍物的方法包括使用旋光仪记录原始图像数据以获得道路或区域的偏振图像。 然后校正图像以获得不均匀性，光学失真和配准。 计算IR和偏振数据产品，并将所得到的数据产品转换成多维数据集用于开发。 对比增强算法被应用于多维图像以形成增强的对象图像。 然后可以将增强的对象图像显示给用户，和/或信号器可以宣布对象的存在。 此外，基于道路中物体的存在，车辆可以采取回避行动。
