摘要:

车辆间距离和相对速度估计是任何ADAS(高级驾驶员辅助系统)的两个基本功能。在本文中,我们提出了一种基于单目摄像头的车辆间距离和相对速度估计方法的基础上,端到端的深度神经网络的训练。该方法的主要创新点在于融合了任意两个时间连续的单目帧所提供的多种视觉线索,包括深度特征线索、场景几何线索以及时间光流线索。我们还提出了一种以车辆为中心的采样机制,以减轻运动场(即光流)中的透视失真的影响。我们实现了一个轻量级的深度神经网络的方法。进行了大量的实验,证实了我们的方法优于其他国家的最先进的方法,在估计精度,计算速度和内存占用方面的优越性能。

英文摘要:

Inter-vehicle distance and relative velocity estimations are two basic functions for any ADAS (Advanced driver-assistance systems). In this paper, we propose a monocular camera-based inter-vehicle distance and relative velocity estimation method based on end-to-end training of a deep neural network. The key novelty of our method is the integration of multiple visual clues provided by any two time-consecutive monocular frames, which include deep feature clue, scene geometry clue, as well as temporal optical flow clue. We also propose a vehicle-centric sampling mechanism to alleviate the effect of perspective distortion in the motion field (i.e. optical flow). We implement the method by a light-weight deep neural network. Extensive experiments are conducted which confirm the superior performance of our method over other state-of-the-art methods, in terms of estimation accuracy, computational speed, and memory footprint.
