In autonomous driving, using a variety of sensors to recognize preceding vehicles in middle and long distance is helpful for improving driving performance and developing various functions. However, if only LiDAR or camera is used in the recognition stage, it is difficult to obtain necessary data due to the limitations of each sensor. In this paper, we proposed a method of converting the tracking data of vision into bird's eye view (BEV) coordinates using an equation that projects LiDAR points onto an image, and a method of fusion between LiDAR and vision tracked data. Thus, the newly proposed method was effective through the results of detecting closest in-path vehicle (CIPV) in various situations. In addition, even when experimenting with the EuroNCAP autonomous emergency braking (AEB) test protocol using the result of fusion, AEB performance is improved through improved cognitive performance than when using only LiDAR. In experimental results, the performance of the proposed method was proved through actual vehicle tests in various scenarios. Consequently, it is convincing that the newly proposed sensor fusion method significantly improves the ACC function in autonomous maneuvering. We expect that this improvement in perception performance will contribute to improving the overall stability of ACC.

P3-LOAM: PPP/LiDAR Loosely Coupled SLAM with Accurate Covariance Estimation and Robust RAIM in Urban Canyon Environment

基于激光雷达(LiDAR)的同时定位与地图构建(SLAM)技术在自动驾驶领域引起了越来越多的关注。然而,LiDAR-SLAM遭受累积误差,这可以通过全球导航卫星系统(GNSS)显著减轻。精密单点定位(PPP)是一种不依赖于基站的高精度GNSS工作模式,在无人系统中越来越受欢迎。针对LiDAR-SLAM和PPP这两种技术的特点,提出了一种将LiDAR-SLAM和PPP相结合的SLAM系统P3-LOAM(PPP based LiDAR Odometry and Mapping)。为了更好地集成,我们通过使用奇异值分解(SVD)雅可比模型推导LiDAR-SLAM定位协方差,因为SVD提供了迭代最近点(ICP)的显式解析解,这是LiDAR-SLAM中的关键问题。然后提出了一种新的方法来评估估计的LiDAR-SLAM协方差。此外,为了提高GNSS在城市峡谷环境中的可靠性,我们开发了一种LiDAR-SLAM辅助GNSS接收机自主完整性监测(RAIM)算法。最后,我们验证P $^3$ -LOAM与UrbanNav,一个具有挑战性的公共数据集在城市峡谷环境。综合测试结果表明,P3-LOAM在精度和可用性方面优于单点定位(SPP)、PPP、LeGO-LOAM、SPP-LOAM以及UrbanNav出版商提出的松耦合导航系统等基准。
