Abstract
We propose a zoom dual-path augmented reality head-up display optical system. The
system uses two image generation units to display the basic and
interactive information. Based on the node aberration theory, the
aberration evaluation function was constructed. By solving the optimal
solution of the aberration evaluation function, the initial structure
of the interactive information display optical path was obtained. In
order to solve the vergence-accommodation conflict in the process of
vehicle speed change, the interactive information optical path was
designed as a zoom optical path. The zoom distance is 10–20 m,
and the basic information optical path will not be interfered with in
the process. In addition, the tolerance analysis of the system was
carried out to prove the machinability and stability of the system.
This study makes the imaging of the augmented reality head-up display
system more in line with the characteristics of the human eye and
improves driving comfort.
