本项目针对大型整体构件现场高效精密加工需求，研究基于多传感器数据融合的组合测量原理与精度调控方法，包括基于多站位测量信息数据配准的基准传递技术，基于内外部检测信息的机器人本体运动学标定技术，计及机器人末端位姿误差的工件三维廓形重构技术。以载人航天空间站舱段仪器接口现场加工系统为背景，利用上述技术搭建原理性仿真与实验验证平台，以期为保障大型构件机器人化加工系统的精度提供重要的技术基础。

To improve the precision and efficiency of in-situ precision machining of large parts, this project aims to develop the combined measurement method and precision control method for fusing system data by profound research on three aspects: reference transfer technology based on registration of multi station measurement data, robot calibration using the mixed internal and external inspection information, and reconstruction of 3D profile based on the robot pose errors. The application of this project is in-situ precision machining of the manned space station cabin instrument interface. A simulation and experimental verification platform will be built using the above technology. The outcome of the project will lay down a solid theoretical and technical foundation in robotized machining system of large parts.
