A Hybrid Spatial-temporal Deep Learning Architecture for Lane Detection

Yongqi Dong, Sandeep Patil, Bart van Arem, Haneen Farah

摘要:

准确可靠的车道检测对于车道保持辅助和车道偏离警告系统的安全性能至关重要。然而,在某些具有挑战性的情况下,它是很难得到令人满意的性能,准确地检测车道从一个单一的图像,主要是在目前的文献。由于车道标记是连续的线,因此如果结合来自先前帧的信息,则可以潜在地更好地推断在当前单个图像中难以准确检测的车道。本研究提出一种新颖的混合时空(ST)序列对一(sequence-to-one)深度学习架构。该结构充分利用多帧连续图像中的ST信息,在最后一帧中检测车道标记。具体而言,混合模型集成了以下几个方面:(a)配备空间卷积神经网络的单图像特征提取模块;(b)由ST递归神经网络构建的ST特征集成模块;(c)编码器-解码器结构,这使得该图像分割问题以端到端的监督学习格式工作。大量的实验表明,所提出的模型架构可以有效地处理具有挑战性的驾驶场景,并优于现有的最先进的方法。

英文摘要:

Accurate and reliable lane detection is vital for the safe performance of lane-keeping assistance and lane departure warning systems. However, under certain challenging circumstances, it is difficult to get satisfactory performance in accurately detecting the lanes from one single image as mostly done in current literature. Since lane markings are continuous lines, the lanes that are difficult to be accurately detected in the current single image can potentially be better deduced if information from previous frames is incorporated. This study proposes a novel hybrid spatial-temporal (ST) sequence-to-one deep learning architecture. This architecture makes full use of the ST information in multiple continuous image frames to detect the lane markings in the very last frame. Specifically, the hybrid model integrates the following aspects: (a) the single image feature extraction module equipped with the spatial convolutional neural network; (b) the ST feature integration module constructed by ST recurrent neural network; (c) the encoder-decoder structure, which makes this image segmentation problem work in an end-to-end supervised learning format. Extensive experiments reveal that the proposed model architecture can effectively handle challenging driving scenes and outperforms available state-of-the-art methods.
