Self-calibration of Laser Tracking Systems

چکیده
In this paper, a methodology for self-calibrating a multi-beam laser tracking measurement system with planar constraints is proposed. A model for the multiple-beam laser tracking system is derived. Through error analysis it is shown that using even rough angular measurement of the gimbal joint positions may improve the overall system calibration results. Parameter observability issues are studied for self-calibrating the multiple-beam laser tracking system. The results reveal the applicability of planar constraints to the system self-calibration. Results of simulation and experimentation on a prototype system are reported to show the applicability of the proposed calibration strategies.

− A new calibration approach of a coordinate measuring machine (CMM) using a laser tracking system is proposed. According to the conventional approach of the laser tracking system, trilateration principle is mainly adapted. Therefore one retroreflector and four laser trackers are required. Though this approach is capable of attaining high accuracy measurement, measuring volume is likely to beco...

Systematic trends are apparent when studying the self-calibration residuals of many modern static terrestrial laser scanners. Since the operation of terrestrial laser scanners is comparable to an efficient robotic total station, the sensor modelling parameters are developed in the spherical coordinate system where the raw observables of the scanner are range, horizontal angle, and vertical angl...
