基于主观评价实验的汽车前照灯配光性能评估方法研究

Experimental Verification of Performance Method for Vehicle Headlighting Systems

CIE188号技术报告发布了一套评估汽车前照灯配光性能的客观计算方法,可用于前照灯配光性能的定量评估。开发了一套专用软件,辅助实现此评估计算功能。此外,为了验证该方法在中国的适用性,本文对四套前照灯的配光性能开展了主观评价实验研究,以探究主观评价实验结果与按照CIE188技术报告计算结果之间的相关性。实验结果表明,CIE188号技术报告中的汽车前照灯配光性能评估方法可以实现不同前照灯配光性能之间的比较,但两种方法得到的结果的相关性不显著。

In order to evaluate the photometric performance of vehicle headlamps with a standardized , accurate and reliable method, the CIE 188 Technical Report specifies a set of certain methods to assess the photometric performance of vehicle headlighting systems .The assessment can be achieved with a self -developed software.Three subjective rating tasks were conducted to verify the rationality of the methods described in this report and the suitableness with Chinese subjects .The comparison between the results calculated according to CIE 188 Technical Report and subjective rating scores indicated there ’s no significant correlation between the two methods .It is necessary to do further research on the methods described in this report.
