长角融合空间坐标测量系统误差建模和标定
Modeling and calibration of system errors in distance-angle fusion spatial coordinate measurement
摘要
Abstract
Facing multi-objective,autonomous,parallel measurement demands in the manufacturing of high-end equipment(e.g.,aviation and aerospace)and the construction and operation of large scientific fa-cilities(e.g.,large radio telescopes),improvements are presented for the distance-angle fusion spatial co-ordinate measurement system previously proposed.The geometric-structure error model has been refined,and a high-precision control-field calibration method based on an adaptive weighted optimization algorithm is introduced.Precise calibration of the system's error parameters was achieved.In indoor calibration ex-periments,the average deviation of coordinates across 24 calibration points was 0.098 1 mm,closely matching the theoretical average deviation from single-measurement simulation.In outdoor astronomical observation conditions,the standard deviation of point-position measurements for 10 observation points was better than 0.021 mm,the maximum tangential displacement comparison deviation of the reflective surface was 0.022 mm,and the maximum gravitational-direction displacement deviation was 0.040 mm.These results demonstrate that the proposed method effectively calibrates the error parameters of the dis-tance-angle fusion coordinate measurement system and satisfies the real-time control requirements for ac-tive surface shape accuracy in astronomical observations.关键词
