| 摘 要： | 介绍了利用摄像头进行眼球自动追踪的技术以及在高速公路景观敏感区研究中的应用,其主要原理是利用图像灰度曲线进行计算,分别获得水平和垂直灰度曲线,接着进行初步定位得到包含眼球在内的矩形区域,然后在此基础上对眼球位置进行精确计算,最后利用图像帧列计算眼球的相对移动轨迹和停留时间,由此可以记录试验者对高速公路景观不同区域的注意程度和关注时间,为高速公路景观研究和应用提供支持。

| Abstract: | The technology of eye-position tracking for impressive highway landscape area using computer camera is put forward.First,the horizontal curve and vertical curve of image gray value are drawn,then a rectangle area including eye is positioned,then the position of eyeball is accurately calculated in this rectangle,the path of eyeball moving and time of eyeball stay somewhere are obtained using video image frames,which indicate the attractiveness of the impressive highway landscape area. |
