3D technology


and aerial survey

Apart from applying 3D laser scanner for architectural and monument protection purposes,
our company was one of the first in Europe to use 3D terrestrial laser scanner on archaeological excavations.
3D terrestrial laser scanner is used to asses important built heritage and national or cultural monuments
that need to be protected, reconstructed or restored. 3D laser scanner has an important role in reconstruction,
since mapping of the current status of a monument helps to reconstruct its original form.
This technique can be used to survey both the interior and exterior of monuments.

Application of 3D terrestrial laser scanner

3D terrestrial laser scanner offers a solution in reconstruction when the original structure of a significant built heritage and national monuments need to be protected, reconstructed or restored. 3D terrestrial laser scanner is capable of accurately scanning the features with complex geometry, which complement and implement the available maps and documentations. The method is particularly suitable for specifying the geometric structure of monuments and assess the condition of their different parts.

Advantages of 3D terrestrial
laser scanning

Large speed scanning

The advantage of 3D terrestrial laser scanning is that in a few minutes it provides accurate information on areas that are difficult to access or on large areas independent of the time of the day (its usability is not affected by the time of the day). As a result, this is one of the fastest (1 million points/sec scanning speed) and most effective method for digital imaging of features with contoured surfaces and complex geometry.

Exceptional accuracy

During the survey the 3D terrestrial laser scanner generates a point cloud and associate parts of the cloud with colours. As opposed to this, a camera takes only pictures and later, during the processing, generates a point cloud, therefore it is less accurate and detailed. By the means of millions of scanned points, we can make calculations with geometric accuracy and the 3D model of the scanned features can be used for visualisation.

Safe surveying

We strongly believe that this complexity makes our work cost- and time effective and at the same time we fully comply with high scientific standards. According to ISO 9001, 14001 and 18001 certificates, all phases of archaeological works are carefully planned and followed up.

The achievements of 3D technology

The point cloud, generated by the 3D terrestrial laser scanner, is processed by the software of the scanner. The point cloud is used to create various reconstructions and virtual tours. By using 3D terrestrial laser scanner and orthophotos, larger areas or features, landscape forms and built structures can be recorded on site. Owing to the applied technology, models can be spectacularly visualised, and the scanned features can also be analysed, cross-sectioned in any numbers and measured with high precision.

What can be done
with the results of the survey?

WHAT CAN BE DONE WITH THE RESULTS OF THE SURVEY AND WITH THE POINT CLOUD?

  • 2D development schedule: site plan, cross-section, facade- and area layout.
  • Photorealistic pictures.
  • Cross-sections or panoramic shots, orthophotos.
  • Rendering.
  • Animations or virtual tours with panoramic shots, point cloud view with measuring capability.
  • Down to the millimetre accuracy, fully dimensioned scale, walk through 3D model.
  • 3D printed model.
