激光跟踪仪主动对准式复合传感高精度姿态测量
High-precision attitude measurement with active aiming composite sensing for laser tracker
摘要
Abstract
To address the requirements of quality inspection and assembly process control in large-scale high-end equipment manufacturing,an active aiming-based attitude measurement target for laser trackers was developed.A comprehensive mathematical model for attitude measurement was established,accom-panied by parameter calibration procedures and nonlinear error compensation methods.The structural com-position,operational principles,coordinate system definitions,and data acquisition and preprocessing tech-niques of the active aiming target were systematically presented.Attitude-solving models were constructed based on constraints derived from laser beam vectors and gravitational vectors.Furthermore,a feedfor-ward neural network was employed to compensate for nonlinear errors inherent in the model-derived atti-tude data.Calibration strategies for parameter matrices and neural network training were formulated and evaluated.Experimental validation,including parameter calibration and attitude measurement,was per-formed using the active aiming target.The results indicate that within a 15 m range,the root-mean-square deviation between the proposed target and a Leica T-MAC sensor is 0.030°,satisfying the precision re-quirements for typical industrial large-scale attitude measurements.关键词
