从轮廓标的功能需求出发,对双向8车道高速公路中轮廓标反光膜尺寸进行研究,首先找出影响轮廓标设置尺寸的各类因素,并依托三看模型确定轮廓标反光膜设置尺寸方案,通过基于光学性能及夜间显著性理论的现场试验对备选方案进行比选,得到各个方案的亮度和灰度变化曲线,最后据此结果得出了高速公路合理的轮廓标反光膜尺寸。 Based on the functional requirements of the contour target, the dimensions of the reflector film in the bidirectional 8-lane expressway were studied. First, the factors influencing the setting dimension of the contour mark were found out, and the dimensions of the reflector film were determined according to the three- Based on the field performance of optical performance and night saliency theory, the alternatives were compared and the curves of brightness and grayscale were obtained. Finally, the reasonable profile size of reflective film was obtained.
