Through extensive testing information disposals and analyses, the autrors illumination should be the optimal parameters of sidewalk lighting and exist problems at present. The computer gray separation method is first used in analysing the facial features of pedestrians at night. It gets the scope of applications and application conditions of three-dimensional sense. The study provide an experimental basis and scientific method for constituting sidewalk lighting evaluation indicators, and provided important values for the study of sidewalk lighting evaluation indicators.
