Problems solved by technology

[0002] The 5-step setting-out construction method of mantis is more commonly used for building decoration measurement and construction setting-out, that is, after the decoration unit enters the site, the project department will combine the general floor plan of each floor and the construction plan according to the axis, control line and elevation line handed over to the civil engineering unit. The actual situation of the site and different construction time nodes, the construction method of measuring and setting out in five steps requires a lot of manual on-site measurement and buried points, a long construction period, and is greatly affected by the site environment.

Embodiment 1

[0081] Embodiment 1: Do a good job of site construction preparation. Before 3D scanning, planar control targets are arranged in advance on the completed civil works. On-site planar targets are required to be posted. As a planar control target, the encrypted control network needs to be seen by the instrument. There are enough control points, and according to the volume size, appearance shape and construction site conditions of the completed civil works, arrange several 3D scanning stations (which can form closed wires), and set 3 stations on the buildings within the scope of each station. ~ 4 targets, which are the splicing of point cloud data measured by the stations of the 3D scanner. No less than 3 public splicing spheres should be arranged between each connected measuring station and the 3 splicing spheres cannot be in a straight line. The measuring station conducts three-dimensional scanning of civil engineering. Each measuring station should not be too far away to ensure t...

Embodiment 2

[0082] Embodiment 2, splicing the cloud models of each station refers to importing the point cloud model into Trimble RealWorks and adopting the point cloud stitching method under the absolute coordinate system, splicing the point cloud models obtained by the three-dimensional scanning of each station into a whole, and then the point cloud model Carry out noise reduction, filter and crop the point cloud model after noise reduction according to the reference objects required for setting out, and delete the noise points that do not belong to the completed civil engineering according to the true color and panoramic photos of the point cloud model;

Embodiment 3

[0083] Embodiment 3, import the floor point cloud and target coordinate points extracted after screening into the Rhino (rhino) software of BIM, and use Rhino+Grasshospper (rhino parametric plug-in) to generate the floor through parameterization of the imported floor point cloud Ground (grid dense, concave-convex ground), the Rhino model of the generated floor ground and target coordinate points is merged with the original structure decoration BIM model, the coordinate system is unified, and the control points are selected according to the characteristics of the lofting curve. Relative to the straight line segment, the two ends and the Midpoint; curved curve segment, in addition to extracting the endpoints and midpoints of different curvature radii, the extraction points should also be added according to the requirements of the processing material and the length of the curve, and the control points on the above curve can be obtained by running the algorithm in the Rhino environm...
