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

小行星9505674 该项目将开发计算机视觉中三维模型构建的新方法。 这些模型将基于立体对和/或通过激光扫描仪获得的3D表面数据。 对于这两种模式中的任何一种，模型构建过程主要由两个连续步骤组成。 第一步提供3D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3D模型验证方法，称为3D模型验证阶段（MVP_）。 在进行拟议的研究时，将讨论四个研究课题：（i）设计一个以三维表面模型形式描述各种几何形状和不规则物体的代表性方案，输入是立体对和/或激光扫描数据;（ii）开发准确融合从多视图获得的数据的方法;（iii）在可同时使用立体影像及激光扫描器的情况下，发展合并表面资料的方法;及（iv）将（i）至（iii）项所用的方法应用于制造业及生物医学工程。 ***

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. ***
