Configuration Requirements for Panoramic Terrestrial Laser Scanner Calibration Within a Point Field

A high-quality point field plays a crucial factor in scanner calibration. However, in most cases, efforts are made to find suitable algorithms and less attention is paid to establishing a point field. This letter focuses on the prediction and planning of quality point fields due to scanner calibration. We first propose specific criteria to assess whether the estimated calibration parameters are accurate enough for panoramic scanners. We relate a statistical bound for the unknown estimate deviations to the standard deviations of the scanner's raw measurements. We then apply the criteria and configuration requirements as the basic building blocks to design a point field and scanner setup plan to determine a subset of frequently used additional parameters (APs) to calibrate an indoor field with separately measured target coordinates. The provided strategy is the local optimal solution, as tested using Monte Carlo simulations and real calibration tasks.
