Abstract
Glasses, a head-up display device and system, and an in-vehicle system for distortion calibration are provided, as well as a distortion correction method. The glasses include a first lens, a second lens, and a correction structure. The correction structure includes first and second standard plates and a polarizers having first and second polarization directions corresponding to the first and second lenses, respectively. The first and second standard plates are configured to enable the head-up display device to generate first and second correction images after receiving first and second distortion images of the first and second standard plates, respectively, based on the first and second distortion degrees of the first and second standard plates, respectively, and on an image to be displayed. The first polarized direction is perpendicular to the second polarized direction.
