Fabricated beam-column component detection system based on mixed reality and construction control method

The invention discloses a fabricated beam-column component detection system based on mixed reality and a construction control method. The detection system is composed of Hololens 2 equipment, an image acquisition system, a point location marking system, a computer PC, an image processing system and a virtual-real superposition system. The construction control method comprises the following steps: firstly, shooting a required beam column component through the image acquisition system and the point location marking system to obtain an image; an image processing system is used for detecting beam column components in real time, data information is stored in a database, and meanwhile information comparison with the fabricated building construction BIM model is carried out to judge the types of the components. And finally, the virtual-real superposition system sends a comparison result to the HoloLens2 equipment in real time, and superposes a virtual model to a real scene, so that information space mapping is reali
