NIGHT LANDSCAPE VISUAL PERCEPTION EVALUATION SYSTEM RESEARCH FOR CHINESE ANCIENT BUIDING

摘要

Objective: Night lighting visual representation of ancient buildings in the city is related to many aspects, ranging from subjective evaluation factors such as highlighting the ancient building images and color performance to subjective sense factors such as brightness and luminance ratio. Also, there still exist visual impacts of the lighting facilities. Considering all these factors, a visual performance evaluation system is requried. Methods: This article is about visual performance evaluation system, combining objective indicators of lighting technology with subjective experience of the visual factors, based on the basic impression of the ancient buildings in the day. The characteristics of ancient architecture are regarded as the basic carrier for presentation layer; lighting color reproduction, brightness highlight and coordination with the surrounding brightness are regarded as visual perception layer; the visual impact of lighting facilities are regarded as technical realization layer. The above three parties are regarded as main evaluation criteria to established 16 evaluation sub-criteria elements. Combined with AHP (Analytic Hierarchy Process) and semantic evaluation model and data analysis, the weight for each evaluation factor is determined. Results: Through the research, a visual performance evaluation system containing 3 evaluation criteria which have 16 sub-criteria together is established. Conclusions: Reliable technological approaches are supplied for further evaluation of the visual perception of traditional Chinese ancient architecture for night lighting.
