核心商区LED显示屏视觉质量评价理论模型研究

Study of LED Display Visual Quality Evaluation Model in CBD

随着LED显示屏在户外的普及与发展,如何对其视觉质量进行合理评价成为亟待解决的问题。本文建立了用于评价核心商区LED显示屏视觉质量的理论模型。首先通过研究LED显示屏的工作原理、物理性质以及相关标准、规范,从物理客观指标和心理主观指标两方面筛选出13个影响LED显示屏视觉质量的评价指标;再将德尔菲法与聚类算法结合,筛选出符合要求的评价指标集;最后运用遗传算法对层次分析法所构建出的初始判断矩阵进行优化并求解出各指标权重,从而构建出核心商区LED显示屏视觉质量评价理论模型。

With the popularization and development of LED display in the outdoors,how to evaluate its visual quality becomes an urgent problem.In this paper,a theoretical model is established to evaluate the visual quality of LED display in CBD.Firstly,study on the working principle,physical properties and relevant standards of LED display,select 13 LED display visual effect evaluation indicators from objective and subjective aspects;then combine Delphi method with clustering algorithm,select the evaluation index set in accordance with requirements;finally,apply GA to optimize the initial judgment matrix constructed by AHP,calculate the index weight and establish the LED display visual quality evaluation model in CBD.
