平面丝织文物在展陈中的重点照明入射角度研究

摘要

以大尺幅平面类丝织文物为研究对象,探讨在悬挂展陈状态下,此类型丝织品在博物馆重点照明设计中的光照设计和视觉感受.通过对重点照明中不同光线入射角下的丝织品表面平均照度和照度均匀度的试验分析,得到了大尺幅平面类丝织文物在悬挂展陈状态下,与之相适应的重点照明光照方式.同时以图像“对比度”中的直方图为评估方法,评价了大尺幅平面类丝织文物在重点照明中的视觉感受.%With large-dimension plane cultural relics of silk fabrics as the research object,this paper discusses lighting design and visual perception of such silk fabrics in accent lighting design in museum under the state of hanging display; obtains the suitable way of accent lighting of large-dimension plane cultural relics of silk fabrics under the state of hanging display through test analysis on average illuminance and uniformity of illuminance of the surface of silk fabrics under different lighting incident angles in accent lighting; and meanwhile evaluates the visual perception of large-dimension plane cultural relics of silk fabrics in accent lighting with histogram in image "contrast"as the evaluation method.
