AR/VR虚拟显示光学测量及IEC国际标准进展

 虚拟现实、增强现实技术近年获得快速发展,但虚拟显示的视觉舒适度、体验感和实用性仍有待提高。如何对虚拟显示的光学性能、图像质量等关键性能指标进行量化评价和准确测量,是产业界非常关注的问题。AR/VR虚拟图像与液晶显示屏等传统显示图像的成像方式不同,测量方法有较大差别,本文根据虚拟显示的成像方式,提出了模拟人眼的入瞳、视野、视角方向及光谱响应等特性的测量技术。同时,结合IEC TC110 WG12"穿戴显示"工作组的标准化工作情况,介绍了AR/VR虚拟显示光学测量方法国际标准化的进展。

Optical measurement of AR/VR virtual display and development of IEC Standards

In recent years virtual reality and augmented reality technologies have developed rapidly, yet the visual comfort, experience and practicality of virtual display still need improvement. How to evaluate and measure the key performance, such as optical performance and image quality of virtual display, is an issue of great concern to the industry. An AR/VR virtual image is different from the traditional display, such as LCD, and the measuring method is also quite different. Based on the imaging mode of virtual display, this paper presents the measurement technology to simulate human eye pupil, vision, angle of view and spectral response. The progress of the international standardization of AR/VR virtual display optical measuring methods is introduced as well in combination with the standardization work by the IEC TC110 WG12 "Eyewear display" working group.
