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 facilities（e.g.，large radio telescopes），improvements are presented for the distance-angle fusion spatial coordinate measurement system previously proposed. The geometric-structure eror 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 experiments，the average deviation of coordinates across 24 calibration points was 0.0981mm ，closely matching the theoretical average deviation from single-measurement simulation. In outdoor astronomical observation conditions，the standard deviation of point-position measurements for 1O observation points was better than 0.021mm ，the maximum tangential displacement comparison deviation of the reflective surface was 0.022mm ，and the maximum gravitational-direction displacement deviation was 0.040mm These results demonstrate that the proposed method efectively calibrates the error parameters of the distance-angle fusion coordinate measurement system and satisfies the real-time control requirements for active surface shape accuracy in astronomical observations.
