    • Systems capable of acquiring polarimetry data using a single camera with or without a polarizing filter. When a polarizing filter is used, the data acquisition method comprises: (1) maneuvering the aircraft (or other vehicle) to orient the polarizing filter (and camera) in various directions when images are captured, (2) registering the various images to each other, and (3) computing polarimetry values (such as the Stokes parameters) for points of interest in the images. When a polarizing filter is not used, the data acquisition method comprises maneuvering the aircraft (or other vehicle) to orient the camera in various directions when images are captured and then performing the same operations (2) and (3). These methods measure the amount of polarization in a given scene by taking multiple camera images at different angles.
    • 能够使用具有或不具有偏振滤光器的单个相机获取偏振数据的系统。 当使用偏振滤波器时,数据采集方法包括:(1)当拍摄图像时,操纵飞机(或其他车辆)以使偏振滤光器(和相机)在各个方向定向,(2)将各种图像记录到每个 其他,和(3)对图像中感兴趣的点计算偏振度值(例如斯托克斯参数)。 当不使用偏振滤光器时,数据采集方法包括操纵飞行器(或其他车辆),以便在拍摄图像时进行相机的各个方向的定向,然后执行相同的操作(2)和(3)。 这些方法通过以不同角度拍摄多个摄像机图像来测量给定场景中的偏振量。
