Description
Summary:Recently, the popularity of 3D in computer graphics or image processing boosts the use of reverse engineering. With the aid of computer-aided design, computer-aided manufacturing and computer-aided engineering techniques, various medical images, historical relics, artworks, or products captured in 2D images (e.g. digital photos or engineering drawings) are changed into 3D solid models for recovery, preservation, entertainment, or visualization, or other downstream applications, etc. In some cases, geometric information from a physical object is always obtained by traditional engineering drawings from different 2D orthographic projections without a 3D scanning device. The input for reverse engineering is necessary to change into 3D solid model for various downstream applications. In this study, a 3D fillet solid model construction is proposed from 2D orthographic projections using CSG representation. The uniqueness of the solid model obtained is proved.
