📝 摘要（中文）
电力分配基础设施的常规检查对地理分散的网络运营商来说仍然具有挑战性，传统的人工检查难以一致且大规模地执行。本文提出了一种基于智能手机的AI检测系统，通过现场人员拍摄的图像评估目标分配基础设施的状况。该工作流程将图像质量和视角验证与AI辅助的杆倾斜、横臂和顶夹具倾斜、电压水平、植被清理风险及配电变压器地面间隙的评估相结合。系统在安得拉邦东部电力分配公司进行试点部署，识别了1,222个缺陷实例，并在整改和验证工作流程中跟踪，研究期间记录了84个缺陷实例的整改。尽管对供电中断记录进行了检查，但现有观察结果不足以证明系统的可靠性改善。还公开发布了一个多模块的现场捕获数据集PD-Defect，以支持分配基础设施检查的可重复研究。
🔬 方法详解
问题定义：本文旨在解决电力分配基础设施检查中的效率低下和缺陷识别不及时的问题。传统的人工检查方法难以在广泛的地理区域内保持一致性和规模化，导致缺陷未能及时发现和处理。
核心思路：论文提出的解决方案是利用智能手机结合AI技术进行现场图像采集和分析，旨在提高检查的自动化程度和准确性。通过深度学习模型和几何分析，系统能够快速评估基础设施的状态。
技术框架：整体架构包括多个阶段：首先进行图像质量和视角验证，然后通过AI模型评估杆倾斜、横臂和顶夹具倾斜等参数，最后将结果整合到一个多阶段的检查工作流程中，适用于实际的现场操作。
关键创新：该系统的主要创新在于将深度学习与单目深度估计和规则基础处理相结合，形成一个统一的检查流程。这种集成方法与传统的手动检查方式有本质区别，显著提高了检测效率。
关键设计：系统设计中采用了特定的损失函数和网络结构，以优化图像分析的准确性。此外，针对不同的检测任务，设置了相应的参数，以确保模型在实际应用中的有效性。

📄 摘要（原文）
Routine inspection of power distribution infrastructure remains challenging for utilities operating geographically dispersed networks, where conventional manual inspection can be difficult to perform consistently and at scale. This work presents a smartphone-based AI inspection system for assessing targeted distribution-infrastructure conditions from images captured by field personnel. The proposed workflow integrates image-quality and viewing-perspective validation with AI-assisted assessment of pole lean, crossarm and top-cleat tilt, voltage level, vegetation-clearance risk, and distribution-transformer (DTR)-ground clearance. The system integrates deep-learning models with monocular depth estimation, geometric analysis, and rule-based processing within a common multi-stage inspection workflow designed for practical field operation. The system was pilot deployed across five selected distribution feeders within the Eastern Power Distribution Company of Andhra Pradesh Ltd. (APEPDCL), where 1,222 defect instances were identified across the assessed categories and subsequently tracked through a rectification and verification workflow, with 84 defect instances recorded as rectified during the study period. Feeder-level interruption records were also examined over the study period; however, the available observations do not provide sufficient evidence to establish a reliability improvement attributable to the proposed system. A curated multi-module field-captured dataset, PD-Defect, is also publicly released to support reproducible research in distribution-infrastructure inspection. The field deployment demonstrates the practical integration of smartphone-based AI-assisted inspection into field inspection and maintenance activities, providing a mechanism for systematic identification, documentation, rectification tracking, and verification of targeted distribution-infrastructure defects.
