PPE_TLSCalibration

Codes for TLS calibration

for project parameter estimation (PPE) course (HS2020) @ ETHZ

Group member: Yue Pan & Fandré Josianne

Supervisor: Prof. Andreas Wieser

Link to project II of PPE: Kriging

Goal: Parameter estimation for the extrinsic & intrinsic calibration of terrestrial laser scanner (TLS)

Environment and Prerequisites: Matlab (2019 or higher) with navigation toolbox

Implementation details:

External loop: robust estimation via Danish method

Internal loop: standard linearized parameter estimation via Gauss-Markov Model

Estimation of initial guess: transformation coefficients estimation via SVD

For more details and experiment results, please check our final report.
