Abstract
The invention discloses a modularized building visual hoisting system and method based on an unmanned aerial vehicle. The system comprises a modularized building hoisting mechanism, a modularized building component information collecting module, a building information model building module and a hoisting operation displayer. The modular building component information acquisition module comprises a plurality of inertial sensors and target assemblies which are installed on modular building components, and an unmanned aerial vehicle used for recording the positions of the target assemblies in high-altitude operation in real time. A camera and a visual identification system are arranged on the unmanned aerial vehicle; the building information model construction module is used for constructing a real-time BIM model of the hoisting process of the modular building component and sending the real-time BIM model to the hoisting operation display; the real-time BIM model of the component and the real image information recorded by the unmanned aerial vehicle around the modular building component are received and displayed through the hoisting operation displayer, so that hoisting personnel can master the real-time position of the modular building component in the hoisting operation process in real time, and efficient and accurate modular building automatic hoisting operation is achieved.
