Summary

Key points include:

- Municipalities increasingly require 3D city models for management and planning purposes.
- Indoor 3D data acquisition is costly and time-consuming, typically using Electronic Distance Measurement (EDM) and Terrestrial Laser Scanner (TLS).
- The Trimble LaserAce 1000 range finder is investigated as a faster and cheaper alternative for indoor data acquisition.
- The range finder's accuracy is evaluated, and a simple 3D model is reconstructed from real data, showing inconsistencies in horizontal angles for short distances.
- A least square adjustment algorithm is used to calibrate the range finder.
- Interval analysis and homotopy continuation are employed to control uncertainties in calibration and building reconstruction.
- The study compares the Trimble LaserAce 1000 with a Leica scanstation C10 for validation.
- The paper reviews indoor building data acquisition techniques, discusses range finder calibration, and addresses uncertainty control.
- Future research is suggested to further improve the method.
