matlab实现停车位车辆检测，主要是利用hough变换实现车道线检测.本程序先是二值化，滤波处理后，利用hough变化检测车道线，故确定车位位置，在车位内根据颜色灰度检测是否有车。(matlab parking space vehicle detection using hough transform lane detection. This procedure first binarization, filtering, hough change detection lane, so to determine the parking position, in the parking according to the color gray-scale detectioncar.)
