This article examines the use of point clouds as a geometric data basis for factory planning and compares different mapping techniques for generating these point clouds. Data and information acquisition is a crucial step in factory planning and thus in developing efficient production processes. In this context, different mapping techniques are analysed: photogrammetry (using drones and action cameras) and LiDAR scans (performed both from drones and from the ground).
The methodology and results of this investigation are discussed in detail, highlighting the advantages and disadvantages of each mapping technique. The focus is on comparing the generated point clouds in terms of completeness, recognisability and geometric tolerance. This comparison provides valuable insights into which technique is best suited for the data acquisition of factory planning. The outlook of this paper includes the further development of recording techniques, particularly with regard to autonomously flying drones. In the future, these could enable more efficient and precise data acquisition for factory planning and thus further strengthen the basis for optimising production processes.

Automated guided vehicles (AGVs) are floor-bound systems,
consisting of several components that can organise the logistical transport of materials in an automated and driverless manner.
The advantages associated with the introduction of AGVs can be particularly interesting for small and medium-sized enterprises (SMEs).
can be particularly interesting. By specifically increasing the degree of automation in the organisation of internal processes with the help of AGVs, an increased volume of material transport can be handled reliably and with high availability.
can be handled reliably and with high availability without
without having to tie up more personnel at the same time. This means that personnel resources can be utilised more efficiently and relieved by using AGVs.

The digital development of spaces within the city of Hannover by means of a digital image makes it possible to cover the usage needs of spaces more efficiently and in line with the requirements. The crea-tion of a digital image, which develops new possibilities for access to public space, requires the use of different sensors such as LiDAR sensors and tracking cameras. In order to select suitable sensors that can be used with UAS, the requirements for the overall system are first defined, which are derived in functional requirements for the sensor technology. Subsequently, the degree of fulfilment of the functional requirements by the different sensors

A concept was developed for the digitization of business processes in a craft enterprise. By introducing a document management system, the functional scope of the ERP system already in use was expanded and the business processes were converted to a paperless office. In addition, a concept for a digital construction file was developed in order to integrate employees in the field into digitized processes.

How can the restructuring of a factory layout be planned efficiently and without errors? Thanks to digital three-dimensional factory planning, the quality of planning projects can be improved and the implementation period shortened. This is demonstrated by the exemplary use of a digital tool in a project of the Mittelstand 4.0 Kompetenzzentrum Hannover at Zerspanungstechnik Kuhn Edelstahl GmbH.

The use of digital assistance systems can contribute to the reduction of non-value-added activities and thus has significant benefits for small and medium-sized enterprises. This is shown by the method-oriented concept development for the introduction of an assistance system at Tietjen GmbH

By using digital tools in the factory planning process, the planning quality can be improved and the duration of the project can be shortened. In order to exploit these potentials, data consistency must be guaranteed throughout the planning process. In this article, digital factory planning tools, used at the Institut für Integrierte Produktion Hannover (IPH), will be presented and their applications and requirements will be discussed.
