基于SPEOS的汽车中控屏防眩目仿真精度影响因素研究

Study on the Influence Factors of the Anti-Glare Simulation Precision of the Vehicle Central Display Based on SPEOS

以某车型为研究对象,针对目前基于SPEOS软件的汽车中控屏防眩目仿真精度低等问题,探讨了眼点位置、环境光学数据输入以及材质光学属性对仿真精度的影响。采用日光眩光概率(DGP)评估模型对仿真结果进行眩光评估,并与主观评价试验的眩光评估结果进行对比分析,结果表明,采用准确的眼点位置、环境光学数据输入及材质光学属性后,其DGP仿真结果与主观评价结果的相关系数平方值R2由0.893提高到0.952,具有更高的仿真精度。

With a car model as the research object,the influence of the eye point location,environmental optical data input and material optical properties on the simulation precision were explored based on the problem of low accuracy of vehicle display anti-glare simulation in software SPEOS.Daylight Glare Probability(DGP)evaluation model was used to evaluate anti-glare performance of simulation results,which was compared with the results of the glare evaluation of subjective evaluation test.The results show that the square value of the correlation coefficient R2 between the DGP simulation results and the subjective evaluation results is increased from 0.893 to 0.952 after the accurate eye point location,environmental optical data input and material optical properties are adopted,and has higher simulation precision.
