摘　　要：人行道照明应考虑人行交通的特点,重视行人的安全性、舒适性,针对人多、低亮度的步行区域的防侵犯照明应尤其引起重视。为了达到防侵犯照明的要求,应采用半柱面照度做为人行道照明的一个重要评价指标。通过人脸模型的辨识实验表明,面部模型主观评价与半柱面照度相关性较好,半柱面照度最适合于分辨面部的表情,所以半柱面照度是人行道等照明场所的防侵犯照明标准中的一个重要指标。The footpath illumination should consider that the foot ty, comfortableness, in view of many people, the low brightness traffic the characteristic, takes pedestrian＇s securi＇s walk region＇s crime prevention lighting should bring to the attention especially. In order to achieve crime prevention lighting request, should use the semi - cylindrical illumination person profession illumination an important evaluating indicator. Indicated through the person face model＇ s identification experiment that the face model subjective appraisal and the semi - cylindrical illumination rel- evance is good, the semi - cylindrical illumination most suits in distinguishes face＇s expression, therefore the semi - cylindrical illumination is illumination place in and so on footpath crime prevention lighting important targets.
