CSG based reconstruction of 3D object in engineering drawing
Xu Zhang · 2015
A 3D object reconstruction algorithm for engineering drawing is proposed based on constructive solid geometry(CSG).By the principle of CSG,execute the compartmentalizing,distinguish and save all graphical primitive pixels within every view area in line with their classification.Combine these pixels to construct basic solids by the rule of projection.Reconstruct the 3Dobject according to the combination relationship of these basic solids.Examples are given to show that,this algorithm can overcome the weakness of badly feature matching and image ghost in 3D object reconstrction.
