Building component three-dimensional pose and vision measurement method based on leveling mark

The invention relates to a building component three-dimensional pose and vision measurement method based on leveling marks. A building floor, a building component, a plurality of leveling marks and a binocular camera system are included. The pattern of the leveling mark comprises a calibration plate pattern and a number pattern, so that automatic classification of data is realized after the leveling mark is shot; the process of shooting the flat mark is determined; a theoretical world coordinate system is established according to coordinate system transformation, the problems of coordinate system overall translation deviation, three-axis rotation deviation and error accumulation caused by a traditional method are avoided, unification of all camera coordinate systems to the theoretical world coordinate system is achieved through coordinate system transformation, and coordinate splicing of a small-breadth camera to a large-size component can be achieved. 本发明涉及一种基于平整标记的建筑构件三维位姿及视觉测量方法，包括楼地面、建筑构件、若干平整标记以及双目相机系统；平
