Structured light stereo scanner

该设备是一种高精度测量装置，用于在室外和室内环境中以点和面积为基础获取物体。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。该系统及其组件用于工程大地测量、摄影测量、土木工程和机械工程领域的基础研究。它用于不同尺寸部件的表面检测、传感器控制以及材料研究中的研究问题。该设备及其部件的特点是，所获得的几何信息以及图像可以在施工现场的任何时间和任何地点转换到给定的对象坐标系中（或生产车间，或大型建筑物），以便建立对上级模型或参考框架的参考。此外，这种转换应该是可行的，没有物理标记，以保证一个完全自动化和非接触式的工作流程。为了完成上述任务，除了作为主要设备的结构光扫描仪（SLS）外，还需要购买高精度和现代化的测量设备：最新一代的机器人全站仪将用于在空间中定位SLS，而GNSS接收器则需要将全站仪定位在参考系中。此外，地面激光扫描仪将用于可靠地连接单个SLS测量。此外，需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设备进行各自的研究问题（在现有项目中），或概述未来工作的计划。根据研究方向和问题，为四个研究小组准备了研究补充表：第一工作组负责制定将补充劳工计划与其他组成部分联系起来的基本程序，即确保上述各项收购的共同登记。第二工作组负责处理与生产表面的质量控制有关的问题，主要用于建筑施工中的增材制造领域。第3工作组使用大型-用于模拟和验证材料科学中各种问题的模型的比例设备和组件。第4工作组处理机器人的定位，物体空间的传感器。这里，通过提供高度精确的环境几何形状来间接使用设备，但是全站仪也用于直接定位空间中的移动的设备。

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.
