Abstract
With the development of the construction industry, safety management issues at construction sites have become increasingly prominent. How to effectively identify hazards at construction sites in real time and ensure worker safety has become an urgent technical problem to be solved. This paper proposes a construction scene hazard identification system based on machine vision, which uses the target detection algorithm YOLO and the deep learning framework ncnn, combined with edge computing equipment, to improve the intelligent level of construction site safety management. The system collects real-time image data of the construction site, uses YOLO to detect and identify hazards, and notifies relevant personnel to intervene through an early warning mechanism, thereby reducing the probability of safety accidents.
The paper first constructed a specialized dataset of hazardous sources for construction sites. Furthermore, to address the issue of computational efficiency in deep learning models, this paper optimized the YOLOv8 model, thereby improving the real-time performance and operational efficiency of the system. Then, the system was deployed on Android phones, achieving low latency real-time recognition functionality.
In the experimental section, this paper validates the advantages of the proposed system in terms of accuracy, real-time performance, and robustness. The experimental results show that this system can not only operate stably in various construction environments, but also accurately identify multiple hazards under complex conditions.
Finally, this paper summarizes the innovative points and shortcomings of the system, and provides prospects for future research. Future research will focus on expanding the system’s multi scenario adaptability, improving detection accuracy and intelligence level, and widely applying them in actual construction sites to further enhance the safety and efficiency of building construction.
