چکیده
This paper presents the achievement of a China NSFC project. A technique to calibrate laser tracker using CMM has been developed. A laser tracker with working range of 35m can be calibrated accurately and quickly using a CMM with working range of 1m. Studies have shown that angular errors are the key contributor to measuring errors of laser tracker. A device to measure angular errors of laser tracker on CMM has been invented. Using this technique to calibrate the laser tracker on the CMM, the maximum measuring error of the laser tracker in measuring distance of 1.56m has been decreased sharply from 91μm to 28μm.

− 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...
متن کاملArticulated Arm Coordinate Measuring Machine Calibration by Laser Tracker Multilateration
A new procedure for the calibration of an articulated arm coordinate measuring machine (AACMM) is presented in this paper. First, a self-calibration algorithm of four laser trackers (LTs) is developed. The spatial localization of a retroreflector target, placed in different positions within the workspace, is determined by means of a geometric multilateration system constructed from the four LTs...

Abstract: In this paper, we present the use of the laser tracker to aid the alignment of a Swing Arm Profilometer (SAP) and measure the length of the swinging arm, thus calibrating the operating radius of the SAP. The measurement uncertainty analysis is given. A laser tracker is used to align the SAP to ensure the path of the probe head passes through the rotary axis of the rotary table. By bui...

متن کاملModeling and Self-calibration of Laser Tracker System Using Planar Constraints
A kinematics model that describes not only the motion but also the geometric variations of LTS is developed. Through error analysis of the proposed model, it is claimed that gimbals axis misalignments and tracking mirror center offset are the key contributor to measuring errors of LTS. A self-calibration method is presented to calibrate LTS with planar constraints. Various calibration strategie...
