基于多位姿标靶的激光跟踪姿态测量系统参数标定
Parameter calibration of laser tracking attitude measurement system based on multi-position targets
摘要
Abstract
The six-degree-of-freedom measurement system based on laser tracking plays a critical role in the production,manufacturing,and assembly of large-scale equipment,where accurate pose measurement is essential for ensuring precise determination of position and orientation.To address the challenges of cali-bration in laser tracking pose measurement systems operating in long-distance and wide-field scenarios,this study presents a novel calibration method leveraging multi-position targets.The methodology focuses on laser tracking systems utilizing cameras,starting with a detailed introduction to the system's architec-ture and pose measurement principles.Subsequently,the pose-solving algorithm is analyzed to identify key factors influencing calibration accuracy.Based on this analysis,a parameter calibration method is de-veloped using spatial multi-pose targets,employing spatial geometric constraints and the least squares prin-ciple for optimal parameter estimation.A laser tracking experimental platform,constructed with a total station and a movable calibration board designed to create a stereotactic target,is used to evaluate the pro-posed method.Experimental results demonstrate that,within a measurement range of 3-15 m,the pro-posed calibration method enhances pose measurement accuracy by over 25.4%compared to conventional techniques.This method offers significant potential for applications requiring high-precision pose measure-ments in long-distance and wide-field environments.关键词
