摘要
为解决山区公路中驾驶视觉信息量难以量化的问题,对驾驶视野图像进行分割,根据HSV颜色模型,提取视野图像的色调、饱和度、亮度值,再结合车速值,在驾驶视觉心理负荷的基础上,提出山区公路路域环境下的驾驶视觉信息量计算方法.通过实车实验,进行数据采集,并验证计算方法.计算结果表明,在半郁闭型空间行驶时,接收的视觉信息量最大;在郁闭型空间中,接收的信息量最小.计算结果与被试实际感受具有一致性,说明本文提出的驾驶视觉信息量计算方法具有可行性,可为路域环境的合理布设提供一定的技术参考.
In order to quantify the amount of driving visual information in mountain highway, driving vision images are first segmented, the HSV color model is used to extract the hue, saturation and brightness values of the vision image, and the driving visual information calculation method of mountain highway is proposed based on driving vision psychological load. A real vehicle experiment is carried out, then the relevant data are collected, and the above calculation method is used and verified. The results show that the visual information received is the largest when driving in the semi closed space, and the one is the smallest in the closed space. The calculated results are consistent with the actual feelings of the test driver. The calculation method of driving visual information is feasible and can provide some technical reference for the reasonable layout of the road environment.
