Description:

Laboratory of Photogrammetry and Remote Sensing is equipped with modern hardware and software technique that allows to address the issue of close-range, aerial, UAV photogrammetry and remote sensing applications. It addresses three fundamental areas of research:

  1. The spatial reconstruction of various objects from their landslides (building structures, objects of historical and cultural heritage protection, geological environment, industrial products etc.).
  2. Automated land mapping by aerial optical recordings while using both manned and unmanned platforms.
  3. Processing of satellite optical recordings and satellite radar interferometry (InSAR).

Within these technologies we solve the issue of accurate 3D models of objects ranging in size from a few mm to hundreds of meters, measuring displacement and deformation of structural components, monitoring of landslide sites, vertical displacement of building structures and the earth's surface, creation of digital elevation models etc.

  

Projects:
