Color Characterization of a Polarization Camera in Comparison with a Conventional Color Camera
Abstract
Abstract

In this study, the color performance of a polarization camera was investigated and compared with that of a color camera. Three experiments were conducted using a well-calibrated imaging system with a 450 CIE configuration. First, among the seven preset equations, the 3 × 11 characterization matrix exhibited a small regression error. Second, the use of unpolarized and polarized light led to different chromatic shifts, particularly for sections with 90 and 0 polarization. Lightness (L) was found to be more closely related to the degree of linear polarization (DoLP), whereas chromaticity showed less correlation. Finally, the impact of the two levels of glossy samples was examined using both the cameras. The surface characteristics of the objects were observed and correlated with variations in the DoLP and chromatic shifts. This work analyzes the color characteristics of a polarization camera from FLIR. These findings contribute to understanding the influence of polarized light sources, color characterization conversions, and sample variations on camera color accuracy.
