摘要:
智能停车系统有助于减少拥堵并最小化用户搜索时间,从而促进智慧城市采用并提升城市交通效率。在先前的工作中,我们提出了一种在大学校园内开发的系统,通过估算感兴趣区域内的车辆数量来监测停车位可用性。尽管这种方法取得了良好的准确性,但它限制了系统提供车位层面洞察和支持更高级应用的能力。为克服这一限制,我们扩展了系统,采用基于距离感知匹配方法和空间容忍度的车位级监控策略,并通过增强适应性边界框划分方法来处理具有挑战性的空间。所提出的方法在资源受限的边缘设备上实现了98.80%的平衡精度,同时保持了8秒的推理时间,增强了YOLOv11m模型(大小为40.5 MB)的能力。此外,还引入了两个新组件:(i)数字影子,它通过可视化停车楼实体作为基础,以演变为完整的数字孪生;(ii)基于改用电视盒的应答支持服务器。后者不仅使云服务、停车亭和提供详细车位占用统计数据的机器人之间实现可扩展的通信,还促进了硬件再利用,作为更大可持续性的一步。
英文摘要:
Smart parking systems help reduce congestion and minimize users' search time, thereby contributing to smart city adoption and enhancing urban mobility. In previous works, we presented a system developed on a university campus to monitor parking availability by estimating the number of free spaces from vehicle counts within a region of interest. Although this approach achieved good accuracy, it restricted the system's ability to provide spot-level insights and support more advanced applications. To overcome this limitation, we extend the system with a spot-wise monitoring strategy based on a distance-aware matching method with spatial tolerance, enhanced through an Adaptive Bounding Box Partitioning method for challenging spaces. The proposed approach achieves a balanced accuracy of 98.80% while maintaining an inference time of 8 seconds on a resource-constrained edge device, enhancing the capabilities of YOLOv11m, a model that has a size of 40.5 MB. In addition, two new components were introduced: (i) a Digital Shadow that visually represents parking lot entities as a base to evolve to a full Digital Twin, and (ii) an application support server based on a repurposed TV box. The latter not only enables scalable communication among cloud services, the parking totem, and a bot that provides detailed spot occupancy statistics, but also promotes hardware reuse as a step towards greater sustainability.
