Construction supervision method and system based on BIM model

The invention discloses a construction supervision system based on a BIM model. The construction supervision system comprises a portable terminal and a plurality of unmanned aerial vehicles. The portable terminal comprises supervision software with a BIM model, and the supervision software can obtain operation actions in the BIM model and positioning data corresponding to the operation actions; and the plurality of unmanned aerial vehicles move to the corresponding positioning points according to the positioning data and feed back the positioning data to the portable terminal. According to the method, the actual measurement size and the size in the BIM model are compared with each other, and positioning measurement and laser ranging are combined to realize positioning calibration and mutual complementation of ranging dead angles. 本发明公开了一种基于BIM模型的施工监理系统，包括便携式终端和复数个无人机；所述便携式终端中包括具有BIM模型的监理软件，所述监理软件能够获取BIM模型中的操作动作以及操作动作对应的定位数据；所述复数个无人机根据所述定位数据运动至相应的定位点，并将定位数据反馈至便携式终端。本发明实现实际测量尺寸与BIM模型中的尺寸相互比较，且定位测量和激光测距相结合实现定位的校
