PROJECT DESCRIPTION

KEYWORDS: Engineering | Architecture | Hospital redevelopment | Heron | 3D Mapping 


The healthcare sector is always in constant evolution. In order to stay at the forefront from the point of view of diagnosis, there is often the need to introduce more advanced machinery whose placement within the hospital space must be adequately planned. In many cases it is necessary to completely rethink the rooms, taking care not to hinder the hospital routine or to cause inconvenience to the patients.
In this specific case, the client decided to proceed with a rapid survey carried out using the HERON instrument, thanks to which it was possible to detect 3 wings in just 20 minutes, simply by walking along corridors, rooms, and stairs. During data processing, it was possible to extract the point cloud 3D model and compare it with existing 2D maps. The plans of the detected environments were then updated: orthophotos of the 3D model were generated and subsequently imported and vectored in CAD.

NEEDS AND GOALS
  • To obtain the real state of the building in order to plan the implementation of new technical rooms.
  • To acquire 2D and 3D data quickly and discreetly without disturbing the guests of the structure.
  • To not interrupt or hinder the regular functioning of the hospital.

HERON AC-1 MAIN BENEFITS
  • Efficiency: time and economic saving.
  • Integration: management of very large dataset, with the possibility of automatically integrating data from terrestrial or handheld laser scanners. 
  • Quick and frequent update of 2D and 3D maps, thanks to Heron’s automatic localization capability. Survey easily managed by operators with minimal knowledge of surveying.
