摘要 传统的视觉表达方法没有考虑夜间雾霾天气带来的影响,降低了交通信号灯视觉传达的效果。为此,提出一种基于双边滤波的增强夜间交通信号灯视觉传达效果的方法。将交通信号灯的RGB空间转换为HSV空间,避免交通信号灯颜色失真的现象;利用双边滤波方法对交通信号灯的亮度进行增强,提高了夜间交通信号灯视觉传达的效果。仿真实验结果表明,改进算法能够增强夜间交通信号灯的亮度和对比度,效果令人满意。 The enhancement effect of the traffic lights at night visual communication is of great importance for maintaining the night traffic order. No night fog weather the impact of the traditional algorithm, which reduces the traffic light visual communication effect. For this, put forward a kind of based on bilateral filter to enhance the effect of traffic lights at night visual communication methods. Traffic lights in the RGB space into HSV space, avoid traffic light color distortion phenomenon; With bilateral filtering method to enhance the brightness of the traffic lights, so as to improve the traffic lights at night the effect of visual communication. The simulation experimental results show that the improved algorithm can enhance the brightness and contrast of traffic lights at night, the effect is satisfactory.
