Large-scale structure space pose online compensation system and method based on multiple laser trackers

The invention provides a large-scale structure space pose online compensation system based on multiple laser trackers. The large-scale structure space pose online compensation system comprises a numerical control positioner, the laser trackers, a reflection target ball, a spherical hinge and a large-scale structure. One laser tracker corresponds to one reflection target ball and is mounted close to the emission target ball; the numerical control positioner is connected with a large-scale structure through a spherical hinge; the plurality of reflection target balls are distributed and mounted on a large-scale structure in a scattered manner; wherein at least three groups of numerical control positioners and laser trackers are arranged. Meanwhile, the invention further provides a method of the system, the problem of low efficiency caused by single-point measurement and iterative attitude adjustment in a traditional large-scale structure attitude adjustment positioning method can be avoided, the attitude adjustm
