为兼顾车道识别的实时性和鲁棒性,有序融合了图像中车道线边缘、边缘方向、车道宽度和边缘灰度等特征信息。同时,在识别第1帧车道图像时对整帧图像进行处理;在识别后续各帧车道图像时,根据上一帧图像的识别结果确定动态约束区,并在约束区域内完成识别。实车道路试验结果表明,通过有序融合各种特征信息和合理设置动态约束区能有效识别路面车道线,且车道跟踪具有较好的精确性和可靠性。
為兼顧車道識彆的實時性和魯棒性,有序融閤瞭圖像中車道線邊緣、邊緣方嚮、車道寬度和邊緣灰度等特徵信息。同時,在識彆第1幀車道圖像時對整幀圖像進行處理;在識彆後續各幀車道圖像時,根據上一幀圖像的識彆結果確定動態約束區,併在約束區域內完成識彆。實車道路試驗結果錶明,通過有序融閤各種特徵信息和閤理設置動態約束區能有效識彆路麵車道線,且車道跟蹤具有較好的精確性和可靠性。

For achieving both the robustness and real-time performance of lane idenfication, the feature in-formation on the edge and its direction and gray scale of lane markings and lane width in the image are sequentially fused. In identifying the first frame of lane image, the whole image frame are processed, while in identifying the fol-lowing frames, dynamically constrained areas are determined according to the identification results of previous frames, within which identification completes. The results of real vehicle road tests show that by orderly fusing vari-ous feature information and properly setting dynamically constrained areas, lane marking identification can be effec-tively achieved with better accuracy and reliability in vehicle lane tracking.
