Intelligent tunnel construction measurement setting-out method based on BIM (Building Information Modeling)

The invention discloses an intelligent tunnel construction measurement setting-out method based on BIM (Building Information Modeling). The method comprises the following steps: establishing a tunnelexcavation BIM model according to drawings, performing format conversion on the established BIM model, and copying to a BIM mobile station; after intelligent total station in-place operation is completed on a measurement setting-out site, connecting the BIM mobile station with an intelligent total station, setting measurement parameters through the BIM mobile station, and controlling the intelligent total station to complete connection and locking, and performing measurement setting-out by using an infrared non-prism; and after a testing station is set up, measuring any point on an excavationsurface, confirming a general distance of the excavation surface, automatically calculating the position of a setting-out point at the mileage by the BIM mobile station, and automatically searching anactual setting-out point a
