The digital management of an archaeological site requires to store, organise, access and represent all the information that is collected on the field. Heritage building information modelling, archaeological or heritage information systems now tend to propose a common framework where all the materials are managed from a central database and visualised through a 3D representation. In this research, we offer the development of a built heritage information system prototype based on a high-resolution 3D point cloud data set. The particularity of the approach is to consider a user-centred development methodology while avoiding meshing/down-sampling operations. The proposed system is initiated by a close collaboration between multi-modal users (managers, visitors, curators) and a development team (designers, developers, architects). The developed heritage information system permits the management of spatial and temporal information, including a wide range of semantics using relational along with NoSQL databases. The semantics used to describe the artifacts are subject to conceptual modelling. Finally, the system proposes a bi-directional communication with a 3D interface able to stream massive point clouds, which is a big step forward to provide a comprehensive site representation for stakeholders while minimising modelling costs.

基于点云数据的建筑遗产信息系统：HIS-PC

考古现场的数字化管理需要存储，组织，访问和表示在现场收集的所有信息。现在，文物建筑信息建模，考古或文物信息系统倾向于提出一个通用框架，其中所有材料都从中央数据库进行管理，并通过3D表示形式进行可视化。在这项研究中，我们提供了基于高分辨率3D点云数据集的内置遗产信息系统原型的开发。该方法的特殊之处在于考虑以用户为中心的开发方法，同时避免了网格划分/下采样操作。所提议的系统是由多模式用户（经理，访客，策展人）和开发团队（设计师，开发人员，建筑师）之间的紧密协作发起的。发达的遗产信息系统允许管理空间和时间信息，包括使用关系语言和NoSQL数据库的广泛语义。用于描述工件的语义要经过概念建模。最后，该系统提出了一种具有3D接口的双向通信功能，该接口能够传输大量的点云，这是向利益相关者提供全面的站点表示，同时将建模成本降至最低的一大进步。
