Abstract:

Complete 3D surface models of real objects can be obtained by integrating several range images, each representing a different view of the object. The mesh generated for these models using existing techniques have irregular connectivity in general. Several remeshing techniques have been proposed to approximate the irregular mesh models with regular meshes, which have several advantages like efficient processing and storage.We present a prototype of a system to generate regular 3D models of real objects from 3D points cloud without prior knowledge of their connectivity, using a simple set up of a single 3D scanner and a turntable. Multiple scans representing different parts of the surface of the object are mapped on a 2D plane using some appropriate technique based on the geometry of the object. This represents the complete 3D surface model like a 2D image, and facilitates the processes of smooth integration, hole filling and regularization. Moreover, the existing and new signal and image processing techniques can also be applied easily.

Keywords: 3D Model Construction, 3D Model Registration, 3D Model Integration, Remeshing.
