Road vehicles — Visibility — Viewing quality evaluation for Head-up displays (HUD)

Apstrakt

This standard provides methods for assessing the driver’s viewing quality of AR images presented within the forward field of view. AR images displayed by a head-up display (HUD) are superimposed onto real-world objects such as preceding vehicles and road surfaces. This document covers both 2D and 3D HUD systems, regardless of the underlying technology, but excludes wearable-type HUDs.

Considering actual driving environments, the driver’s viewing quality is assessed from the following perspectives:

- To define the factors that affect visual comfort when viewing AR images and specifying their measurement methods;
- To assessing AR images in terms of depth perception;
- To assess spatial resolution and the relationship between the physical resolution and the perceived resolution of AR images.
