proposed a calibration method of target tracking rotary table based on coordinate transformation. By establishing a precise calibration model of the rotary table, the experimental results showed that the tracking accuracy of the vehicle-borne opto-electronic tracking system can be improved to 0.1\({}^{\circ}\). [PERSON] et al. [5] studied the theodolite calibration method, experimentally analyzed the error factors of the calibration system, and improved the calibration accuracy of the angular displacement of large rotary tables. [PERSON] et al. [6] proposed a simple and efficient calibration method for the rotation angle of a single-degree-of-freedom rotary table based on a laser tracker, and established the relationship between the spatial position and the angle. Its angular positioning deviation is reduced to 5\({}^{\prime\prime}\). [PERSON] et al. [7] proposed a geometric error detection method for rotary feed drive, which mainly used a laser interferometer and plane mirror instead of photoelectric autocollimator and multiface prism to improve the geometric accuracy. The experimental results showed that the angular positioning deviation can reach 4.77\({}^{\prime\prime}\). [PERSON] et al. [8] proposed a new method of adjusting error compensation based on angle calibration, which compensated the adjustment error of photoelectric autocollimator, and angular positioning deviation is as low as 0.922\({}^{\prime\prime}\). The experiment proved the rapidity and reliability of the method.  
However, the above-mentioned calibration method for angular positioning deviation of the rotary table involves high-precision optical instruments such as a laser interferometer and a photoelectric autocollimator and involves the construction of an optical path, which takes a long time and cannot meet the requirements of fast and efficient calibration. The method of calibrating the rotary table by mounting optical components such as multisurface prism on the spindle is not suitable for large rotary tables, because it is difficult to install a multisurface prism with the high installation accuracy. In the method of calibrating the rotary table by the laser tracker, because the tracking angle range of the laser tracker is small, the full circumference measurement cannot be realized. The electronic theodolite calibration method can avoid the difficulties in determining the rotation center of an eccentric rotary table and the small field of view of the autocollimator, but it is difficult to select the observation points and the calibration accuracy is not high.  
This paper proposes a calibration method for angular positioning deviation of a high-precision rotary table based on the laser tracer multi-station measurement system. The mapping relationship between the coordinate information of laser tracer and rotation angle of the rotary table was established based on the high-precision relative interference length of the laser tracer, so as to realize the calibration of the angular positioning deviation of the rotary table. The algorithm error of calibrating the high-precision rotary table based on the laser tracer multi-station measurement system were analyzed. The calibration method was experimentally verified.
