Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document is Part 20-10 of GB/T 48075 "Eye-Wearing Displays". GB/T 48075 has already published the following parts.

--Part 20-10.Basic Test Methods for Optical Performance;

--Part 20-20.Basic Test Methods for Image Quality;

--Part 22-10.Optical performance of AR special test methods this document is equivalent to IEC 63145-20-10:2019 "Eye-worn displays - Part 20-10.Basic test methods - Optical performance".

The following minimal editorial changes have been made to this document.

a) The full English name of "CCD" in 3.2 is corrected to "charge-coupled device" to ensure consistency of the abbreviation;

b) Add positive and negative signs to the arrows in Figure 1 to indicate the positive and negative angle directions, which facilitates the representation of data;

c) Add "Note 2.For multiple point measurements, the measurement methods and calculation formulas described below in this document use 9-point measurements as an example." to section 5.4.

d) Add "%" to formula (5) to make it easier to understand and express the completeness;

e) According to the principle of consistency of the equal sign in the formula, "deltau'v'" in formula (6) should be corrected to "deltau'v'(i,j)";

f) Based on the context, "(deltau'v')max" in 6.5.3 and 6.5.4 should be corrected to "[deltau'v'(i,j)]max";

g) In 6.8.2 g), Dyi1 is corrected to Dy11, and (Dyi2, Dxi1, Dxi2) in h) is corrected to (Dy12, Dx11, Dx12).

h) 6.8.2 j) is corrected to (Dyi2, Dxi1, Dxi2) as "Dyi1, Dyi2, Dxi1, Dxi2" is missing from the context.

Introduction

To meet the needs of my country's manufacturing, inspection, and import/export trade of eye-wearing display products, a series of standards for eye-wearing displays have been formulated.

GB/T 48075 "Eye-Wearing Displays" is proposed to consist of the following parts.

--Part 1-2.Terminology. The purpose is to define eye-worn displays such as augmented reality, virtual reality, and mixed reality, and their image or video rendering...

A term related to dyeing.

--Part 20-10.Basic Test Methods for Optical Performance. The aim is to describe the standard measurement conditions and...

--Part 20-20.Basic Test Methods for Image Quality. The aim is to describe the standard measurement conditions for image quality in eye-worn displays and...

Measurement methods.

--Part 21-20.Special Test Methods for VR Image Quality - Screen Door Effect. The aim is to describe standard measurement criteria for the screen door effect.

--Part 22-10.Optical Performance of AR-Specific Test Methods. The aim is to describe the optical performance of (optical) see-through augmented reality eye-worn displays.

Standard measurement conditions and methods for the optical characteristics and imaging quality of displays.

--Part 22-20.AR-Specific Test Methods for Image Quality. The aim is to describe the standards for image quality in augmented reality eye-wear displays.

Preliminary measurement conditions and methods.

1 Scope

This document describes the standard measurement conditions and methods for the optical performance of eye-worn displays.

This document applies to both non-see-through (virtual reality "VR" glasses) and see-through (augmented reality "AR" glasses) devices that use virtual optical maps.

Like an eye-worn monitor.

This document does not apply to contact lens-type eye-wear displays and direct retinal projection eye-wear displays.
