This utility model discloses an intermediate standard and an automated scanner calibration system. The intermediate standard is used in the calibration of 3D scanners. The intermediate standard includes a main body and recognition heads. An annular recognition area is provided on the main body. Several recognition markers are provided within the annular recognition area for recognition by a scanner located above the main body and a tracker located at any point around the main body. Several recognition heads are provided on the main body, protruding from the main body in the height direction. Several recognition markers are provided on the outer surface of each recognition head, and the tracker can recognize some of the markers on the recognition heads at any point around the main body. The design of the annular recognition area and recognition heads reduces the limitations on the placement of the tracker and scanner in the calibration process, making the formulation of the automated calibration process more flexible and improving the applicability and versatility of the intermediate standard and this calibration system.
