摘要: 城市排水管网系统是城市管理的重要组成部分。通过计算机视觉和人工智能技术在街景图像中自动检测雨水渠的状态,是智慧城市建设的重要方面。基于YOLOv5s,本文提出了一种街景视角下的雨水渠检测框架(YOLO-SDD)。通过分析小尺度目标的特征,YOLO-SDD专注于优化主干网络及其损失函数。一系列实验证明,在不同环境条件下检测雨水渠不同状态的任务中,YOLO-SDD平均精度(mAP@.5)可以达到89.6%,相较于基准模型YOLOv5s提高了2%。在有遮挡与无遮挡的情况下,雨水渠检测的平均精度分别提高了0.9%和3.1%。此外,进一步利用来自美国伊利诺伊州厄巴纳-香槟市的雨水渠数据集(SDUC)和用于航拍图像目标检测的数据集(DOTA)验证了YOLO-SDD的有效性和泛化能力。最后,将YOLO-SDD部署在Android系统上,验证了其在街景中实时检测不同状态雨水渠的能力。

Abstract: Urban drainage pipe system is an important part of city management. Automated detection of the status of storm drain in street-level images through current technologies in computer vision and AI is an important aspect of smart city construction. In this paper, a framework based on YOLOv5s for storm drain detection (YOLOSDD) in street view is proposed. By analyzing the characteristics of small-scale targets, YOLO-SDD focuses on optimizing the Backbone network and its loss function. Series of experiments demonstrated that in the task of detecting different states of storm drain under various environmental conditions, the mean average precision (mAP@.5) of the YOLO-SDD can reach 89.6%, increasing by 2% compared with the baseline model YOLOv5s. In the presence and absence of occlusion, the average precision of storm drain detection increased by 0.9% and 3.1%, respectively. In addition, the effectiveness and generalization ability of YOLO-SDD were further validated using the storm drain dataset of Urbana-Champaign (SDUC) from Illinois, USA, and the dataset for object detection in aerial images (DOTA). Finally, this work has deployed the YOLO-SDD on the Android system, which verifies its ability of real-time detecting storm drain in different states in street scenes.
