The 3D Model Acquisition Pipeline
Three-dimensional (3D) image acquisition systems are rapidly becoming more affordable, especially systems based on commodity electronic cameras. At the same time, personal computers with graphics hardware capable of displaying complex 3D models are also becoming inexpensive enough to be available to a large population. As a result, there is potentially an opportunity to consider new virtual rea...
متن کاملA Simulation of Automatic 3D Acquisition and Post-processing Pipeline
This paper presents a simulation of automatic 3D acquisition and post-processing pipeline. The proposed methodology is applied to a LASER triangulation based scanner and a 6 degrees of freedom (DOF) robotic arm simulation. The viewpoints are computed by solving a set covering problem to reduce the number of potential positions. The quality of the view plan is determined by its length and the pe...
متن کاملAutomating the 3D Modeling Pipeline
We describe advances in automating the 3D modeling pipeline to create rich 3D textured models. Our work is aimed at large scale site modeling, where much manual effort is often needed to create complete models. We present i) an automatic 2D-3D registration method for texture using cast shadows as a cue to refine the registration parameters, ii) methods for change detection in an acquired model,...
متن کامل3D Model Acquisition from Uncalibrated Images
In this paper we address the problem of recovering 3D models from uncalibrated images of architectural scenes. We propose a simple, geometrically intuitive method which exploits strong rigidity constraints such as parallelism and orthogonality present in indoor and outdoor architectural scences. We show how these simple constraints can be used to calibrate the cameras and to recover the 3 x 4 p...
متن کاملFast 3D Model Acquisition from Stereo Images
We propose a fast 3D model acquisition system that aligns intensity and depth images, and reconstructs a textured 3D mesh. 3D views are registered with shape alignment based on intensity gradient constraints and a global registration algorithm. We reconstruct the 3D model using a new Cubic Ray Projection merging algorithm which takes advantage of a novel data structure: the linked voxel space. ...
