题 目 基于B/S架构的人体三维模型管理系统 摘 要 在现今社会，全球数据信息资源日益丰富，空间数据量也不断地在增加。数据库技术也是管理大量信息的关键计算机技术之一。而三维（3D, 3-Dimensional）技术的迅速发展，近几年来受到了越来越多的广泛关注。随着计算机硬件环境的不断发展与三维建模技术的提高，三维数据已经逐渐结合到许多应用领域中，促进了诸如数字城市、远程医疗、军事仿真、多媒体娱乐等多学科交叉的新型领域的发展。由于三维数据精确记录了物体表面的几何信息以及物体在空间的三维信息，既有助于三维模型的形态分析和几何测量，也便于从各个角度观察三维物体，从而得到更准确的信息。而“点云”数据正是三维扫描的结果[1]。 人体三维模型在近几年3D技术迅猛发展的形势下，得到越来越频繁的使用。然而对于这些大量的三维模型数据，目前有的管理系统都是基于C/S架构，并没有基于B/S机构的、方便和易于使用的工具来有效管理它们。基于以上的情况，基于B/S架构的人体三维模型管理系统将会成为三维数据管理领域的一个极具潜在使用价值的系统。 本论文从当前的环境背景出发，讨论了基于B/S架构的人体三维模型管理系统的实际意义，利用几个成熟的处理框架，实现了这个系统。 关键词：三维数据；3D；点云数据；point cloud；管理系统；B/S架构 ABSTRACT In today's society, the global data resources are increasingly rich, spatial data also continue to increase. Database technology is one of the key management of large amounts of information computer technology. The three-dimensional (3D, 3-Dimensional) technology is developing rapidly in recent years attracted more and more attention. With the improvement of computer hardware environment continues to develop three-dimensional modeling techniques, three-dimensional data has been gradually incorporated into many applications, such as promoting the development of digital cities, telemedicine, military simulation, multimedia entertainment and other new interdisciplinary field. Since the three-dimensional surface data accurately record the geometric information and three-dimensional objects in space information, it will help form a three-dimensional model of analysis and geometric measurements, but also easy to observe the three-dimensional object from all angles, resulting in more accurate information. The "point cloud" data is the result of three-dimensional scanning [1]. In the context of the three-dimensional model of the human body in recent years, the rapid development of 3D technology, get more and more frequent use. However, for such a large number of three-dimensional model data, the current management systems are based on some C/S architecture, and is not based on B/S institutions, conve
