Abstract
We developed a polarimetric imaging drone for field inspections of CSP Heliostats. By utilizing the polarization pattern of the skylight calculated with the Rayleigh scattering model, the difficult scenarios for visible images show a good enhancement in the contrast of features, such as edges and cracks of the heliostat mirror facets. Analysis of the test results carried out at Sandia NSTTF validated the feasibility of applying this method and system to the CSP fields. Future work is desired for image fusion of high-resolution visible images and polarization images with well-designed angles.
