Research on Early Warning of Intrusion into Hazardous Construction Area Based on BIM and Machine Vision Technology

为解决建筑施工过程中工人入侵危险区域的预警问题,利用建筑信息模型(BIM)技术和机器视觉技术在建筑施工领域的应用优势,将BIM技术与机器视觉技术相结合,实现建筑施工现场危险区域的入侵预警。首先将LEC评价法用于危险区域划分,确定建筑施工现场危险区域类型的等级划分原则;其次结合IFC的特性,构建建筑施工危险区域的IFC拓展框架,便于危险区域的BIM表达,并分析机器视觉技术在人员定位和危险区域定位中的应用;最后将BIM技术与机器视觉技术相结合,构建了建筑施工现场危险区域施工人员入侵预警模型。实例应用结果表明:提出的危险区域人员入侵预警方法能根据建筑施工现场施工人员的位置信息进行相应的预警,从而降低了施工人员入侵危险区域行为的发生,提高了建筑施工现场的安全管理水平。

In order to solve the early warning problem of workers invading hazardous area during the construction process,this paper combines the Building Information Model(BIM) and machine vision technology with its application advantage in the construction field to realize the early warning of intrusion into hazardous area in the construction site.Firstly,the paper uses LEC evaluation method to classify hazardous area and determine the classification principle of construction site.Secondly,the paper combines the characteristics of IFC to construct the IFC expansion framework for hazardous construction area,which facilitates the BIM expression in hazardous area,and analyzes the application of machine vision technology to personnel positioning and hazardous area positioning.Finally,the paper combines BIM with machine vision technology to construct the early warning model of intrusion for hazardous construction area.The research shows that the early warning method can carry out corresponding early warning according to the position information of construction personnel,reduce the occurrence of intrusion behavior at the accident site and improve the safety management level of the construction site.
