Detection of Small Water-Bodies
Abstract
This paper provides information on how we have utilized two approaches for detection of small water bodies. The first approach requires use of an existing custom camera enclosure with three polarization filters at 0, 45, and 90 degrees, intrinsically mounted, such that these filters and associated optics view exactly the same scene and so all three views are optically co-registered. The other approach requires use of three physically distinct cameras with the same type of polarization filters mounted on three low-cost off-the-shelf cameras each with similar optics, running with certain geometric approximations due to the flat-earth assumption. There are pros and cons for each approach. Results for an actual deployment are presented.
