Systems can obtain polarization measurement data by using a single camera with a polarizing filter or without a polarizing filter. When the polarizing filter is used, a method for obtaining data includes the steps of: (1) operating an aircraft (or other transportation means) to set a direction of the polarization filter (and a camera) to various directions; (2) registering various images with each other; and (3) calculating polarization measurement values (for example, stokes parameters) for points of interest in the images. |
