摘要(Abstract):
频闪效应可视度SVM指标相较于传统频闪评价指标有较好的改进,目前在国际上认可度较高,但SVM指标与频闪对健康的影响并未建立较好的联系并且指标限值尚不统一。本研究通过频闪视觉疲劳评价实验分析得出SVM指标可以用于预测频闪对视觉疲劳的影响程度,并提出3种不同影响程度对应的SVM取值范围。研究结果可为后续频闪评价标准体系的建立提供技术支撑。
Stroboscopic effect visibility measure has a better improvement than traditional TLA indicators, which has a high degree of international recognition, but no research has shown that SVM is in connection with the health effects of TLA. Therefore, in this paper we set an evaluation experiment of the effect of TLA on visual fatigue. The results showed that SVM can be well used to predict the effect degree of TLA on visual fatigue, and SVM value ranges corresponding to three different effect levels were given, which can provide a technical support for the subsequent establishment of TLA evaluation standard system.
