数据结构课程设计时，所需的封面及任务书版面，希望对大家有点用！(Curriculum design data structure, the necessary task of the book cover and layout, in the hope that we are a bit used!)

基于视频的车道线检测,首先对视频进行一系列预处理，然后进行边缘检测，霍夫变换直线检测，最后对检测出来的直线进行非车道线排除。(Video-based lane detection, the first of a series of video preprocessing, edge detection and Hough transform line detection, finally detected non-linear lane excluded.)
