Calibration of Terrestrial Laser Scanners

The standardized approach for the user calibration of terrestrial laser scanners is still missing. Our aim is a development of a generally-accepted user-oriented calibration approach. The current efforts focus on the improvement of the promising point-based self-calibration approach by incorporating recent advances in the field.

Target-based self-calibration

Panoramic terrestrial laser scanners are in the main attention of the research.

Proposed modifications for the existing calibration approaches are tested both in the large indoor facility and rooms of common dimensions.

Basement Experiment

 

Our previous researches were based on the attempt of calibrating the terrestrial laser scanner by using a single object, the radio telescope antenna.
