Our UAV services in the field of monument protection and digitisation of cultural assets:

Non-contact 3D measurement, digital inventory and 3D documentation

  • 3D drone measurement using UAV photogrammetry and UAV laser scanning in the monument protection zone
  • Inventory recording and three-dimensional drone documentation for digitisation of cultural objects
  • Stone measurement of facades using UAV photogrammetry using high resolution and calibrated camera systems or LiDAR scanners
  • True-to-scale, high-resolution facade documentation using UAV photogrammetry
  • 3D measurement and digital inventory (in grayscale or colour) using terrestrial laser scanners
  • Non-contact registration of listed buildings and their frames, additions, decorations, windows and doors
  • Inventory study using UAV photogrammetry and terrestrial photogrammetry in combination with terrestrial colour laser scanning
  • High resolution 3D scans of relics with or without texture for digitisation of cultural goods
  • Fast and inexpensive 3D inventory using mobile laser scanning

Photogrammetric image processing and evaluation of 3D laser scans:

  • Photogrammetric image processing and textured point cloud processing
  • Point cloud recording and processing from UAV and ground-based laser scans
  • Simultaneous recording and processing of raw photogrammetric and LiDAR (laser scanning) data
  • Georeferenced orthophotos of the historical inventory in different scales and resolutions
  • 3D measurement and digital inventory (in grayscale or colour) using terrestrial laser scanners
  • High resolution facade views in the form of orthophotos (corrected survey images) as a basis for planning and damage mapping
  • Digital Elevation Models (DHM), Digital Terrain Models (DTM) and Digital Surface Models (DOM)

3D modelling (CAD models), creation of 2D plans (CAD plans) and facade drawings

  • 2D plans: as-built plans, floor plans (with/without orthophotos), sections (longitudinal and cross sections), views, facade plans
  • Façade drawings to scale: line drawings and image plans (facade drawing, including orthophotos)
  • 3D models (3D CAD models) of historic buildings and the entire historic facility

Digitisation, 3D visualisation and 3D modelling (textured frame models) of monuments and cultural assets

  • Visual inventory, measurement and archiving by 3D scanning (photogrammetry and/or laser scanner)
  • High resolution 3D city models as well as planning models of historic old towns, ensembles, historic complexes and ancient sites
  • High-resolution 3D models of terrestrial and area monuments
  • High resolution 3D models of monuments for digital tours, web / virtual reality applications and public relations
  • High-resolution 3D models of technical monuments and complex free-forms such as sculptures, etc.
  • 3D volumetric mesh models with or without texture for accurate and/or photo-realistic reconstruction and restoration
  • 3D mesh models with high-resolution textures for damage mapping
  • 3D visualisation and photorealistic renderings

3D measurement and evaluation in the field of monument protection

We face special challenges in the field of monument protection and conservation. Not only are we required to always record architectural monuments, historic old towns, historic ensembles and complexes completely and in high resolution, but we are also obliged to meet the high accuracy requirements of monument protection.
The basis for the renovation and conversion of existing historic buildings is an accurate planning basis. This also applies to documentation (damage) in the field of conservation and protection of monuments. In addition to digital plans and building sections, they also include full-scale, high-resolution facade views.
We measure complex structures, digitize historical inventories and document the current condition both three-dimensionally and as high-resolution measurement images. We always use the latest technical aids such as drones, calibrated cameras, state-of-the-art workstations, GPS rovers, total stations and, of course, 3D laser scanners.

Results of a 3D measurement and documentation in the monument protection zone

We compute 3D point clouds from the raw recorded data. The point cloud is already the result of a 3D measurement or 3D inventory. The high density of the point cloud allows the representation of complex objects as well as surface structures.
Dimensions can be taken from the point cloud, measured distances or formed areas. In addition, other results such as geo-referenced orthophotos, facade views and 3D terrain models as well as height models can be obtained. In CAD modelling, the point cloud is used as a building block to create 3D models, as-built plans, floor plans (with/without orthophotos), sections (longitudinal and cross sections), views and facade plans.

Digitisation of cultural goods

The wave of digitisation can be felt in almost all areas of the economy, and the digitisation of cultural goods is more popular than ever. On the one hand, valuable cultural assets, historic buildings, monuments and complex free forms need to be recorded, documented, catalogued and archived. The digital data recorded and processed also forms a basis for planning renovation measures and reconstruction.
On the other hand, highly detailed 3D scans with high-resolution textures can ideally be used to transform cultural assets in the virtual world. For example, once a historic city district or listed object is scanned in three dimensions and in colour, it is available in digital form and can be used in an incredibly versatile way. The current state is saved after scanning and can be kept for eternity. Further processing of 3D data can take place at any time in the future.
