BIM (Building Information Modeling)-based three-dimensional roaming inspection method and system for coal preparation plant equipment

The invention provides a BIM (Building Information Modeling)-based three-dimensional roaming inspection method and system for coal preparation plant equipment. The system comprises the steps that a three-dimensional BIM model of coal preparation plant equipment is established, an unmanned aerial vehicle is used for obtaining a remote sensing image, equipment positioning coordinates are obtained through a target recognition network, the BIM model is associated with equipment sensor data, a roaming inspection path is generated in a virtual roaming three-dimensional space, the path is converted into an unmanned aerial vehicle movement track, and an inspection report is automatically generated. According to the invention, the inspection efficiency is effectively improved, real-time monitoring and early warning are realized, and accurate data support is provided for equipment maintenance and performance optimization. In addition, the operator can monitor the state of the equipment in real time through virtual roam
