摘要:

对于智能汽车来说,感知3D环境是第一步,但也是关键的一步。在本文中,我们建立了一个实时的【形】先进的驾驶辅助系统的基础上,低功耗的移动平台。该系统将立体匹配算法与基于机器学习的障碍物检测方法相结合,充分利用了GPU和CPU的移动平台分布式计算技术,是一个实时的【形】多方案集成创新系统。首先,提出了一种多尺度快速MPV(Multi-Path-Viterbi)立体匹配算法,该算法能够生成鲁棒、准确的视差图。在此基础上,提出了一种基于单目和双目融合技术的机器学习方法来检测障碍物。本文还提出了一种基于张氏标定方法的自动快速标定机制。最后,采用分布式计算和合理的数据流规划,保证了系统的运行效率。实验结果表明,该系统能够实现智能车辆对环境的鲁棒、准确的实时的【形】感知,可直接用于商业实时的【形】智能驾驶应用。

英文摘要:

For intelligent vehicles, sensing the 3D environment is the first but crucial step. In this paper, we build a real-time advanced driver assistance system based on a low-power mobile platform. The system is a real-time multi-scheme integrated innovation system, which combines stereo matching algorithm with machine learning based obstacle detection approach and takes advantage of the distributed computing technology of a mobile platform with GPU and CPUs. First of all, a multi-scale fast MPV (Multi-Path-Viterbi) stereo matching algorithm is proposed, which can generate robust and accurate disparity map. Then a machine learning, which is based on fusion technology of monocular and binocular, is applied to detect the obstacles. We also advance an automatic fast calibration mechanism based on Zhang's calibration method. Finally, the distributed computing and reasonable data flow programming are applied to ensure the operational efficiency of the system. The experimental results show that the system can achieve robust and accurate real-time environment perception for intelligent vehicles, which can be directly used in the commercial real-time intelligent driving applications.
