Abstract

Safety investigators are challenged by the manual task of analyzing large volumes of accident videos through the repetitive process of reviewing them frame by frame, which is both tedious and labor-intensive. This paper proposes the Accident Video Analysis framework (AcciVid), which automates this process using a large multimodal model (LMM) integrated with Graph Retrieval Augmented Generation (Graph RAG). Accident video content and regulations are converted into Resource Description Framework (RDF) triples and stored as graphs, enabling regulation-based analysis through Graph RAG. AcciVid detected 90 %p more potential safety violations than human safety investigators, achieving an F2 Score of 82.4 % compared to their F2 Score of 54.8 %. Furthermore, AcciVid required only an average of 42 s to generate a draft report, whereas human safety investigators needed an average of 4.6 h. This demonstrates AcciVid's potential as an assistant to safety investigators in reducing manual workloads while maintaining high accuracy and efficiency.
使用大型多模态模型和图形检索增强生成的建筑安全事故视频自动分析
安全调查人员面临着手动分析大量事故视频的挑战,他们需要一帧一帧地重复审查这些视频,这既繁琐又费力。本文提出了事故视频分析框架(AcciVid),该框架使用集成了图检索增强生成(Graph RAG)的大型多模态模型(LMM)实现了事故视频分析过程的自动化。事故视频内容和法规被转换成资源描述框架(RDF)三元组并存储为图形,从而可以通过Graph RAG进行基于法规的分析。AcciVid检测到的潜在安全违规行为比人类安全调查人员多90%,其F2得分为82.4%,而人类安全调查人员的F2得分为54.8%。此外,AcciVid生成报告草稿平均只需42秒,而人类安全调查人员平均需要4.6小时。这表明AcciVid作为安全调查人员的助手,在减少人工工作量的同时保持高精度和高效率的潜力。

期刊介绍: Automation in Construction is an international journal that focuses on publishing original research papers related to the use of Information Technologies in various aspects of the construction industry. The journal covers topics such as design, engineering, construction technologies, and the maintenance and management of constructed facilities. The scope of Automation in Construction is extensive and covers all stages of the construction life cycle. This includes initial planning and design, construction of the facility, operation and maintenance, as well as the eventual dismantling and recycling of buildings and engineering structures.
