Abstract

A construction safety intelligent inspection method based on BIM + AR and a knowledge base comprises the steps of constructing a construction safety knowledge graph and a knowledge base, constructing a BIM information base, constructing an augmented reality inspection scene based on BIM, performing safety knowledge retrieval based on BIM information and constructing a construction safety BIM + AR intelligent inspection system, and utilizing technical means of BIM, AR, natural language processing and deep learning. Knowledge assistance is provided for managers in real time in the construction safety inspection process, inspection real-time feedback is guided to be completed, and the defect that the construction site safety inspection effect is limited by the experience of the managers and the difference of the standard cognition level is overcome. According to the method, intelligent knowledge guidance of safety inspection is realized, inspection omissions caused by insufficient experience, unskilled mastering of specifications and regulations and the like of managers in a multi-specialty cross construction scene are avoided, comprehensive and rapid identification of potential safety hazards is guaranteed, and the probability of accidents is reduced.
