A Study on the Simulation System of Landscape Lighting and the Luminance Perception

Considering the characteristics of vision in different luminance levels and the errors of the visual angle restituting, this research obtains a series of simulant scenes and the quantity relations between the luminance of actual scenes and reappearance scenes in the low luminance and weak contrast environment. Finally, carrying the subjective evaluation of these scenes, it obtains the scope of luminance and the quantification relations among these stimulus by statistical analysis. This paper provides theoretical basis for scene simulation and evaluation, and obtain quantitative suggestions for corresponding standards. It has important theory significance and the practical value for landscape lighting planning and design.
