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. ***

[505674] Farag该项目将开发计算机视觉三维模型构建的新方法。这些模型将基于由激光扫描仪获得的立体对和/或三维表面数据。对于这些模式中的任何一种，模型构建过程主要由两个顺序步骤组成。第一步提供三维对象的表示；这个步骤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_）。在进行建议的研究时，将涉及四个研究课题：(i)以三维表面模型的形式设计表征方案，以描述各种几何和不规则物体，输入是立体对和/或激光扫描数据；（ii）发展从多个视角获得的数据精确融合的方法；在有立体成像和激光扫描仪的情况下，发展合并地表信息的方法；以及（iv）在制造和生物医学工程中(i)至（iii）中使用的方法的应用。＊＊＊
