چکیده

Reconstruction of 3D solid models from 2D images has a wide range of important applications like Engineering production and design, character animation and multimedia, and bio medical imaging. Boundary representation (B-Rep) and constructive solid geometry (CSG) are two most widely accepted techniques for 3D modeling. In this paper we have proposed a novel CSG technique by introducing a new type of sweep, “Spiral Sweep”. Our technique requires only single view and embeds topological information in basic CSG primitives to reconstruct 3D model of a helix. We have reviewed some very significant approaches emerged typically for engineering industry and compared these approaches with our approach. Our approach addresses the 3D reconstruction of helix in engineering drawings from single view which is not catered yet. Key-Words: CSG, 3D reconstruction, B-rep, Spiral sweeps, Helix

A Genetic Algorithm based Optimization Method in 3D Solid Reconstruction from 2D Multi-View Engineering Drawings

There are mainly two categories for a 3D reconstruction from 2D drawings: B-Rep and CSG that both these methods have serious weaknesses despite being useful. B-Rep method which has been older and have wider function range is problematic because of high volume of calculations and vagueness in answers and CSG method has problem in terms of very limited range of volumes and drawings that it can an...

Characterization and Investigation of Grain Selection in Spiral Grain Selectors during Casting Single-Crystal Turbine Blades

Manufactured single crystal components using Ni-base super alloys are routinely used in the hot sections of aero engines and industrial gas turbines due to their outstanding high temperature strength, toughness and resistance to degradation in corrosive and oxidative environments. To control the quality of the single crystal turbine blades, particular attention has been paid to grain selection,...

A New Approach for Quantitative Evaluation of Reconstruction Algorithms in SPECT

ABTRACT Background: In nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance.  In this study the Hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. The phantom is modified to acquire t...

Reconstruction of 3D interacting solids of revolution from 2D orthographic views

3D CAD is replacing 2D CAD to improve efficiency of product design and manufacturing. Therefore, converting legacy 2D drawings into 3D solid models is required. CSG based approaches reconstruct solid models from orthographic views more efficiently than traditional B-rep based approaches. A major limitation of CSG based approaches has been the limited domain of objects that can be handled. This ...
