3D Reconstruction from Single 2D Image

چکیده
The perception of 3D scene with stereovision is the capability of human vision but it is a challenge to computer systems. The challenge is to obtain 3D geometric shape information from planar images. This is termed as 3D reconstruction. It is usually done in a piece-wise fashion by identifying various planes of the scene and from those planes constructing a representation of the whole. The image is captured from a calibrated camera. The captured image is perspectively distorted. These distortions are removed by corner point estimation. The selected points give the true dimensions in the input image using view metrology. Then a 3D geometrical model is constructed in VRML according to true dimensions from metrology. In rendering, a texture map is created to each corresponding surface of a polygon in VRML model. VRML supports for walkthrough to a rendered model, through which different views are generated.

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...

Introduction: The purpose of this study is to define the optimal parameters for the tomographic reconstruction procedure in a routine single photon emission tomography. The Hoffman brain phantom is modified to evaluate the reconstruction method. The phantom was imaged in a 3 and 2-dimensional conformation and the results were compared. Materials and Methods: The 2D phant...

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...
متن کاملUnsupervised 3D Reconstruction from a Single Image via Adversarial Learning
Recent advancements in deep learning opened new opportunities for learning a high-quality 3D model from a single 2D image given sufficient training on large-scale data sets. However, the significant imbalance between available amount of images and 3D models, and the limited availability of labeled 2D image data (i.e. manually annotated pairs between images and their corresponding 3D models), se...

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...
متن کامل3D Reconstruction from a Single Image
A probabilistic framework for 3D object reconstruction from a single image is introduced in this work. First, a probabilistic generative model to represent the distribution of mass of a class of objects in 3D space, namely a 3D shape prior, is presented. Next, following the Beer-Lambert law in optics, a framework to translate these 3D probabilities into the corresponding 2D probabilities in the...
