The results of experiments in developing a method for extracting three-dimensional information from a scene by means of a polarimetric passive imaging sensor are summarized. This sensor provides a full Stokes vector at each sensor pixel location from which degree and angle of linear polarization are computed. The angle of linear polarization provides the azimuth angle of the surface normal vector. The depression angle of this surface normal vector is obtained in terms of the emitting object's index of refraction from the solution of an equation derived from Fresnel equations, Snell's law, and percent of linear polarization. Results of the application of this approach to simulated infrared polarimetric data are provided.
总结了利用偏振被动成像传感器从场景中提取三维信息的方法的实验结果。该传感器在每个传感器像素位置提供完整的斯托克斯矢量,并据此计算线性偏振度和角度。线性偏振角提供了表面法线矢量的方位角。通过从菲涅耳方程、斯涅尔定律和线性偏振百分比导出的方程的解,根据发射物体的折射率获得该表面法线矢量的俯角。给出了该方法应用于模拟红外偏振数据的结果。
