摘要
车辆压线检测系统可对车辆运行过程中发生的压线行为进行检测并做出警告,避免由于司机注意不集中、疲劳驾驶、驾驶陋习等原因导致车辆偏移而造成交通事故。对此提出一种基于车载视频的压线检测与车道偏移预警方法。首先,利用合成数据方法构造丰富多样的压线检测数据集;然后,结合图像语义分割方法完成车道线检测;最后,利用当前车道双边线多个几何参数对车辆压线行为作出检测并做出预警。实验表明,单帧平均压线检测准确率为93.7%,耗时78ms,车道偏移预警召回率为93.5%,该方法具备一定的实际应用价值。
Lane-crossinging detection system can detect line-crossing behavior of vehicle and raise warning,which can be used to avoid traffic accident due to lack of concentration,fatigue driving,bad habits of driving and so on.To tackle this issue,a lane-crossing detection and lane-departure warning method based on vehicle video is proposed.Firstly,the method uses synthetic data method to build a rich and varied lane-crossing detection dataset.Then,it accomplishes lane line detection with semantic segmentation.At last, it detects lane-crossing behavior and raises warning using several geometric parameters of2lines of current lane.Results show the method achieves an average precision of 93.7% for lane-crossing detection,takes an average time of 78 ms,and achieves an average recall rate of 93.5% for lane-departure warning,which means the method is robust and practical.
