 **注意:**
  - 车道线中间线自动判断条件：在采样的视频段内同时有两个相反方向的车辆，且判断一次后固定，不再更新；
- - 因摄像头角度以及2d视角问题，车道线中间线判断存在不准确情况，可在配置文件手动输入中间线坐标

 **Note:**
  - Automatic judgment condition of lane line middle line: there are two vehicles in opposite directions in the sampled video segment, and the judgment is fixed after one time and will not be updated;
- - Due to camera angle and 2d visual angle problems, the judgment of lane line middle line is inaccurate. You can manually enter the middle line coordinates in the configuration file
