Abstract

In recent years, there is a growing interest in advanced driver assistance systems, which can reduce the risk of accidents on various roads. Many vehicular technologies use camera information to collect roadside information. But research and development of image recognition in embedded environments is challenging. Therefore, there is a requirement for research to apply open source image recognition technology to embedded platform. Deep learning, a technology that has been on the spotlight recently, shows excellent performance in image recognition. However, deep learning has a problem that the network size and amount of computation are too large. In this paper, we design and implement a deep learning based object recognition system to recognize vehicles on the road. We recognize vehicles using Faster-RCNN, which has excellent object recognition capabilities. However, it is problematic to apply it to an embedded device due to the feature of deep learning. Therefore, we propose and evaluate the performance of object recognition with quantization and pruning. Through the evaluation, we will show that the proposed system reduces the network size to 16% and reduces the operating time to 64% without a significant decrease in recognition accuracy.
基于深度神经网络压缩的车载摄像系统设计与实现
近年来,人们对先进的驾驶员辅助系统越来越感兴趣,因为它可以降低各种道路上发生事故的风险。许多车辆技术使用摄像头信息来收集路边信息。但是嵌入式环境下图像识别的研究和发展是具有挑战性的。因此,研究将开源图像识别技术应用于嵌入式平台就显得十分必要。最近备受关注的深度学习技术在图像识别方面表现出色。然而,深度学习存在一个问题,即网络规模和计算量太大。在本文中,我们设计并实现了一个基于深度学习的物体识别系统来识别道路上的车辆。我们使用Faster-RCNN来识别车辆,它具有出色的物体识别能力。然而,由于深度学习的特性,将其应用于嵌入式设备存在问题。因此,我们提出并评估了量化和剪枝的目标识别性能。通过评估,我们将证明该系统在识别精度没有明显下降的情况下,将网络大小减少到16%,将操作时间减少到64%。
