VR头戴设备显示屏质量评价方法研究与实践

Research and Practice on Quality Evaluation Method of VR Head-mounted Display

目前还没有统一的VR头戴显示设备显示屏质量评价方法,因而无法对不同VR设备显示屏的质量进行对比。本文针对VR头戴式显示设备显示屏尺寸小、视场角大、且需要通过透镜等光学设备成像的特点,参考已有的高清电视监视器的评价指标,对现有的测试方式进行了改进,得到适用于VR显示屏的质量评价方法,该方法主要的测试指标为:黑电平亮度、对比度、基准白、基色色度坐标、GAMMA、运动图像拖尾时间等;并依照此方法对市面上常见的十种VR头戴显示设备完成了测试,为VR头戴显示设备的选择提供了依据。

At present,there is no unified evaluation method of the display quality of VR headset display equipment,so it is not possible to compare the quality of the display of different VR devices.Aiming at the characteristics of small display size,large field of view and need to be imaged by optical equipment such as lens,this paper improves the existing testing methods and gets the quality evaluation method suitable for VR display.The main test indexes of this method are as follows:black level brightness,contrast,datum white,base color chromaticity coordinates,GAMMA,motion image trailing time,etc.,and according to this method,the 10 kinds of VR headset display equipment common on the market have been tested,which provides the basis for the selection of VR headset display equipment.
