Recently, high-accuracy Airborne laser surveying equipment has been used to construct high-precision 3D spatial information such as “DigitalTwin” national land promotion. However, due to the characteristics of the Airborne laser surveying equipment, displacement, etc. may occur when the equipment is attached or detached, so calibration must be performed to correct the system error. In this study, in order to conduct a more reliable performance calibration of Airborne laser surveying equipment, an integrated calibration site was installed to match the characteristics of domestically introduced Airborne laser equipment, and a total of nine Airborne laser surveying equipments were put in to perform. A method for verifying the vertical and horizontal position accuracy for the point cloud data that was later calibration was presented. As a result of verification, it was confirmed that the vertical position accuracy was about ±10 cm and the horizontal position accuracy was about ±15 cm. It is considered that more reliable Airborne laser surveying should be performed in the future by continuously operating and managing the integrated test site selected in this study.
