The equipment is a high-precision surveying device for the point-based and area-based acquisition of objects in outdoor and indoor environments. The requirement is to obtain highly detailed surface and image information using a structured light scanner. The system and its components are used for basic research in the fields of engineering geodesy, photogrammetry, civil engineering and mechanical engineering. It is used for surface inspection of components of different sizes, for sensor control and for addressing research questions in the context of materials research.The equipment, as well as its components, is characterized by the fact that the obtained geometric information, as well as the images, can be transformed into the given object coordinate system at any time and any place of a construction site (or a production hall, or a large building), in order to establish a reference to a superordinate model or reference frame. In addition, this transformation should be doable without physical markers in order to guarantee a fully automated and contact-less workflow. In order to fulfill the outlined tasks, it is necessary to purchase, besides the structured light scanner (SLS) as the main device, further high-precision and modern surveying equipment: a robot totalstation of the latest generation is to be used to orient the SLS in space, whereby GNSS receivers are necessary to position the totalstation in the reference frame. Furthermore, a terrestrial laser scanner will be used to reliably link individual SLS measurements. Furthermore, it is necessary to use software that connects the individual components independently of manufacturers and stores data centrally.In the attached documents, scientists from 4 German universities describe how they will use the equipment for their respective research questions (in existing projects), or outline plans for future work. The research supplement forms are prepared for four research groups according to the research directions and questions:Working group 1 is concerned with the development of basic procedures for linking the SLS with the other components, i.e. to ensure the above-mentioned co-registration of the individual acquisitions.Working group 2 deals with questions concerning the quality control of produced surfaces, mainly in the field of additive manufacturing in building construction.Working group 3 uses the large-scale equipment and components for the simulation and verification of models for various problems in materials science.Working group 4 deals with the positioning of robots and sensors in object space. Here, the equipment is used indirectly by providing highly accurate environment geometry, but also the totalstation is used to directly position the mobile devices in space.

该设备是一种高精度的测量设备，适用于室外和室内环境中基于点和区域的目标采集。要求是使用结构光扫描仪获得非常详细的表面和图像信息。该系统及其组成部分用于工程大地测量学、摄影测量学、土木工程和机械工程等领域的基础研究。它用于不同尺寸部件的表面检查，用于传感器控制和解决材料研究背景下的研究问题。该设备及其部件的特点是，可以在建筑工地（或生产车间，或大型建筑物）的任何时间和任何地点，将所获得的几何信息以及图像转换为给定的物体坐标系，以便建立对上级模型或参照系的参考。此外，这种转换应该可以在没有物理标记的情况下进行，以保证完全自动化和非接触式工作流程。为了完成概述的任务，除了以结构光扫描仪（SLS）为主要设备外，还需要购买高精度和现代化的测量设备：使用最新一代的机器人总站来对SLS进行空间定位，其中需要GNSS接收器将总站定位在参照系中。此外，地面激光扫描仪将用于可靠地连接单个SLS测量。此外，有必要使用独立于制造商连接各个组件并集中存储数据的软件。在所附的文件中，来自4所德国大学的科学家描述了他们将如何使用这些设备来解决各自的研究问题（在现有项目中），或者概述了未来工作的计划。研究补充表格是根据研究方向和问题为四个研究小组编写的：第一工作组负责制定将SLS与其他组成部分联系起来的基本程序，即确保上述个别收购的共同登记。第2工作组处理有关生产表面质量控制的问题，主要是在建筑施工中的增材制造领域。第3工作组使用大型设备和部件对材料科学中各种问题的模型进行模拟和验证。第4工作组处理机器人和传感器在物体空间中的定位问题。在这里，设备通过提供高度精确的环境几何来间接使用，但总站也用于直接在空间中定位移动设备。
