L-YOLO:适用于车载边缘计算的实时交通标识检测模型

在车载边缘计算单元中,由于其硬件设备的资源受限,开发适用于车载边缘计算的轻量级、高效的交通标识检测模型变得越来越迫切。文中提出了一种基于Tiny YOLO改进的轻量级交通标识检测模型,称为L-YOLO。首先,L-YOLO使用部分残差连接来增强轻量级网络的学习能力;其次,为了降低交通标识的误检和漏检,L-YOLO使用高斯损失函数作为边界框的定位损失。在TAD16K交通标识检测数据集上,L-YOLO的参数量为18.8 M,计算量为8.211 BFlops,检测速度为83.3 FPS,同时mAP达到86%。实验结果显示,该算法在保证实时性的同时,还提高了检测精度。

L-YOLO:Real Time Traffic Sign Detection Model for Vehicle Edge Computing

In the vehicle edge computing unit,due to the limited resources of its hardware equipment,it becomes more and more urgent to develop a lightweight and efficient traffic sign detection model for vehicle edge computing.This paper proposes a lightweight traffic sign detection model based on Tiny YOLO,which is called L-YOLO.Firstly,L-YOLO uses partial residual connection to enhance the learning ability of lightweight network.Secondly,in order to reduce the false detection and missed detection of traffic signs,L-YOLO uses Gauss loss function as the location loss of boundary box.In the traffic sign detection dataset named TAD16K,the parameter amount of L-YOLO is 18.8M,the calculation amount is 8.211BFlops,the detection speed is 83.3FPS,and the mAP reaches 86%.Experimental results show that the algorithm not only guarantees the real-time performance,but also improves the detection accuracy.
