3-D Model Building in Computer Vision: New Approaches and Applications

9505674法拉格该项目将为计算机视觉中的3-D模型建立开发新的方法。这些模型将基于立体对和/或激光扫描仪获得的3-D表面数据。对于这两种模式中的任何一种，建立模型的过程主要由两个连续的步骤组成。第一步是提供3-D对象的表示；这一步称为数据表示和注册阶段(DRRP)。第二步开发三维模型验证方法，称为三维模型验证阶段(MVP_.在开展拟议研究时，将涉及四个研究主题：(1)设计以立体对和/或激光扫描数据为输入的三维表面模型形式的代表性方案；(2)开发从多个视角获得的数据的精确融合的方法；(3)开发在立体成像和激光扫描仪都有的情况下合并表面信息的方法；(4)将(1)-(3)中使用的方法应用于制造和生物医学工程。***

9505674 Farag The project will develop new approaches for 3-D model building in computer vision. These models will based on stereo pairs and/or the 3-D surface data obtained by a laser scanner. For either of these modalities, the model building process consists of two mainly sequential steps. The first step provides a representation for 3-D objects; this step is called the Data Representation and Registration Phase (DRRP). The second step develops methods for 3-D model verification and is called the 3-D Model Verification Phase (MVP_. Four research topics will be addressed while carrying out the proposed study: (i) design of a representational scheme in the form of a 3-D surface model describing various geometric and irregular objects, the input being stereo pairs and/or laser scanned data; (ii) development of methods for accurate fusion of data obtained from multi-views; (iii) development of methods for merging surface information in situations where both stereo imaging and laser scanners are available; and (iv) application of the methods used in (i)-(iii) in manufacturing and biomedical engineering. ***
