The contribution is part of an interdisciplinary research that aims to address the problems of knowledge, interpretation and documentation of vulnerable structures such as the brick Renaissance domes ...
Different applications or users need different model (differ requirement on level of details; geometry and information), less focuses in topological element. Improper manage geometry, attribute and to...
The point cloud generated by multiple image matching is classified as an unstructured point cloud because it is not regularly point spaced and has multiple viewpoints. The surface reconstruction techn...
In the framework of the digital documentation of complex environments the advanced Geomatics researches offers integrated solution and multi-sensor strategies for the 3D accurate reconstruction of str...
This paper introduces some studies developed regarding the Medicea Villa at Poggio a Caiano, in Italy. The monumental building was built by Lorenzo de’ Medici and his heirs following the design of the...
3维多输入多输出(3D-MIMO)系统能有效提升频谱效率,提高系统容量。但用户数和天线数的剧增,无法保证所有用户的导频都正交,给3D-MIMO信道估计带来估计精度下降和复杂度增加等问题。该文分析了上行3D-MIMO系统信道的结构稀疏特性和低秩特性,并基于这些特性提出一种信道估计算法,给出了算法的收敛性和复杂度。仿真结果表明估计算法能准确地恢复3D-MIMO的信道系数,并有较低的复杂度。
