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 calibration 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 lasertracking systems utilizing cameras,starting with a detailed introduction to the system's architecture 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 developed using spatial multi-pose targets,employing spatial geometric constraints and the least squares principle 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 3-15m ,the proposed 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 measurements in long-distance and wide-field environments.
