摘要

假设一个标准针孔相机模型，我们展示了一个校准的“比例因子”和一个简单的公式，它将沿平行于公路方向的直线的距离变化与图像垂直坐标的变化联系起来。利用这个比例因子，我们可以通过跟踪连续时间标记图像中的车辆图像来估计车辆速度。

One-parameter camera calibration for traffic management cameras

Assuming a standard pinhole camera model, we show that there is a calibrating "scale factor" and a simple formula that relates the change in distance along a line parallel to the highway direction to a change in the image vertical coordinate. Using this scale factor, we can estimate vehicle speeds by tracking vehicle images in successive time-tagged images.
