DEVELOPMENT OF THE MODELS SHOWING THE EXTENT OF NATURAL SURVEILLANCE BY USING LIGHT PROJECTING METHOD

—Study on windows suffering burglary damage of detached house surrounded by lots—

Abstract

By using “Light Projection Method” in the 3-dimentional model, the simulation system was developed to visualize the extent of natural surveillance covering windows in the case of detached houses each of which is adjacent to one street. In this model, the strength of natural surveillance was visually showed as the brightness generated by artificial light that indicates the visibility. This simulation was evaluated in accordance with the results of the on-site research of actual houses suffering burglary damage.
