Photogrammetric research

The researchers are mainly involved in applied photogrammetric research, to a lesser extent in remote sensing research, including urban ecological research.

Main research areas:

  • Investigation of the automation of photogrammetric orientations.
  • Development of new pattern and shape matching algorithms based on digital stereo image pairs.
  • Comparative analysis of gross-error filtering procedures.
  • For solving nonlinear photogrammetric problems, combining the equilibration procedure with Jacobi mean formation and the Gaussian least squares method into one procedure to increase the computational / processing efficiency.
  • Production and accuracy testing of digital terrain models.
  • Application possibilities of digital terrain and surface models
  • Field calibration of UAV-based complex systems
  • Camera calibration in lab
  • Terrestrial laser scanner measurements
  • Point cloud processing

Some previous tasks:

  • Photogrammetric spatial resection without iteration.
  • Gross-error filtering for photogrammetric calculations before the equalization procedure.
  • Solution of spatial similarity transformation without iteration.
  • Development of a 3D archiving system for archaeological finds for museology.
  • Automated character recognition on medieval maps.
  • UAV camera calibration based on field test field.
  • Development of a camera quality control system.
  • Development of urban ecological studies based on complex data packages (space imagery, digital terrain models, aerial imagery, laser point clouds)
  • Laser scanning of trees and processing of the resulting point clouds

Keywords: photogrammetry, gross-error filtering, digital terrain modelling, 3D modelling, aerial triangulation, point cloud, adjustment calculations in photogrammetry, urban ecological studies with remote sensing methods
