Abstract

The spherical target is the standardization target of the laser scanner performance evaluation commonly used by international metrology institutions. How to obtain the spherical center coordinates of the target by using a higher precision class instrument is an important prerequisite for realizing the spatial performance calibration of the laser scanner. A split target set is proposed, which can be concentric with the laser scanner target by machining and adjusting. The extended uncertainty of the reference distance formed by the split target sets can reach 0.07 mm under the effective length of 3 m, which can be effectively applied to the spatial distance indication error calibration of the laser scanner.
