Application of Polarized Light in UAV Navigation

Shiqi Lan

Abstract


This paper analyzes the advantages and disadvantages of UAV from the perspective of polarization. Inspired by the LCD and the improved gray-scale difference method of auto focus, it realizes the precise navigation and positioning of UAV and improves the image quality in three aspects: improving the color saturation, enhancing the focus function and enhancing the sensitivity of image transformation.
