A Point Cloud Projection Drawing Method Based on Spatial Construction
In order to solve the problem of misdrawing when using three-dimensional laser point cloud data to draw architectural draw-ings,this paper compared and analyzed the similarities and differences between the traditional architectural design drawing process and the point cloud projection drawing process,and designed a point cloud projection drawing method based on spatial construction.Taking a temple in Conghua District,Guangzhou City as an example,a conceptual architectural space was established to verify the structural logic of the compo-nents identified based on the point cloud projection surface,and the correct component feature lines were drawn.The research results show that this method can effectively reduce the problem of misdrawing.
