Abstract

In the current paper, we describe a three dimensional indoor positioning system for the metal industry. The developed system consists of a three dimensional map-based user interface scanned with Leica ScanStation 2, Chirp Spread Spectrum modulation (CSS) indoor positioning technology, and a used positioning algorithm. The system development process described in this paper includes three phases. Firstly, the modelling of three dimensional virtual environments with an accuracy of 2 centimeters required the use of point cloud processing software and 3D content creation. The next phase was to find reliable indoor positioning technology for harsh industrial conditions. The results reported in this paper show that a reliable positioning system using CSS could be created. Finally, location information provided by CSS was shown in the three dimensional map-based user interface. The user interface was based on CENTRIA's Locawe platform. The process described in this paper shows that moving objects such as mobile robots, autonomous transporters or working machines can be tracked in a three dimensional virtual environment.

室内定位用激光扫描模型在金属行业

本文介绍了一种用于金属工业的室内三维定位系统。该系统由徕卡ScanStation 2扫描的三维地图用户界面、Chirp扩频调制(CSS)室内定位技术和一种常用的定位算法组成。本文所描述的系统开发过程包括三个阶段。首先，三维虚拟环境的建模精度为2厘米，需要使用点云处理软件和3D内容创建。下一阶段是为恶劣的工业条件寻找可靠的室内定位技术。本文的研究结果表明，利用CSS可以建立一个可靠的定位系统。最后，将CSS提供的位置信息显示在基于三维地图的用户界面中。用户界面基于CENTRIA的Locawe平台。本文描述的过程表明，可以在三维虚拟环境中跟踪移动物体，如移动机器人，自主运输车或工作机器。
