RECONSTRUCTION OF CONSISTENT 3D CAD MODELS FROM POINT CLOUD DATA USING A PRIORI CAD MODELS
Industrial Plants Modeling Point Cloud CAD Model Reverse Engineering Bayesian Reconstruction
2012/9/3
We address the reconstruction of 3D CAD models from point cloud data acquired in industrial environments, using a pre-existing 3D model as an initial estimate of the scene to be processed. Indeed, thi...
PRIMITIVE-BASED 3D BUILDING RECONSTRUCTION METHOD TESTED BY REFERENCE AIRBORNE DATA
Building Reconstruction LiDAR Optical Imagery Primitive-based Accuracy Evaluation
2012/7/31
Airborne LiDAR data and optical imagery are two datasets used for 3D building reconstruction. By study of the complementarities of these two datasets, we proposed a primitive-based 3D building reconst...

A 3D auto-regressive model for bidirectional prediction
3D auto-regressive model bidirectional prediction
2009/12/31
In this paper, a 3D auto-regressive (AR) model is proposed for bi-directional prediction. The prediction is composed of two 3D AR models, which are along the forward and backward directions, respectiv...
3D密码的不可能差分攻击
分组密码 3D密码 不可能差分攻击
2009/10/26
3D密码是在CANS2008上提出的一个新的分组密码算法，与以往的分组密码算法不同，它采用了3维结构。密码设计者给出了3D密码的一个5轮不可能差分并对6轮3D密码进行了不可能差分攻击。该文通过3D密码的结构特性找到了新的6轮不可能差分。基于新的不可能差分和3D密码的等价结构，可以对7轮和8轮3D密码进行有效的不可能差分攻击。此外，结合其密钥扩展规则，可以将攻击轮数提高至9轮。该文的攻击结果优于密码...
3D-Wedgelet分解与工业CT体数据面特征提取
面特征提取 3D-Wedgelet 工业CT 体数据
2009/6/23
面特征是描述工业CT体数据组成的重要成分之一。在工业CT体数据中，大部分的面特征不是以独立的形式存在，而是以不同灰度区域边缘面的形式存在。多尺度几何分析方法中的3D-Wedgelet恰好能有效刻画这种结构。该文先分析了单尺度下Planelet的形状和内在联系，得到一种快速3D-Wedgelet分解方法。以此为基础，提出两种提取工业CT体数据面特征的方法。(1)基于多尺度3D-Wedgelet分解提...
