摘要:
针对传统利用摄像头识别的车道线侧向定位技术中,因车道或者其左右边界点匹配错误导致换道等工况下行驶易造成较大定位误差的问题,本文结合换道识别方法,首先提出了多指标加权评价地图匹配算法,设计了车道左右边界点确定方法;然后,在准确匹配到车道和其边界点的基础上,提出了一种基于摄像头的双边界线侧向定位方法,提高了车辆相对车道的侧向定位精度;最后,将摄像头与全球定位系统(GPS)、惯性测量单元(IMU)、轮式里程计和轻量化车道级地图融合形成一个完整的定位系统。实验结果表明,与传统利用摄像头与车道线融合定位方法相比,本文设计的定位系统精度和稳定性有了明显提升,为自动驾驶定位提供了一种低成本、高精度的解决方案。
