In the process of cabin segment pose measurement

a cabin segment pose measurement method based on multi-sensor fusion is proposed to meet the requirements of large size and high measurement precision for cabin segments.Firstly

the mathematical model of the pose measurement system is established

and the coordinate system of the cabin segment is defined.Then

the camera imaging coordinate data and the laser ranging data are fused.Combined with the analytical method

direct attitude measurement is realized

and the six-dimensional pose data of the cabin is solved.Finally

error source analysis and simulation analysis are conducted for the pose measurement system

and the six-dimensional measurement error of the cabin segment is calculated through experimental measurements.The simulation and experimental results demonstrate that this measurement method has high measurement precision

which verifies its effectiveness and stability.The method can meet the practical application requirements of docking cabin segment pose measurement.
