摘　　要：飞机装配部件具有尺寸较大且形状复杂的特点,装配后的尺寸与理论模型存在偏差,且飞机型面的测量数据量庞大,因此设计一种高效且准确的飞机外形测量方法对保证飞机装配精度至关重要。建立了激光跟踪仪与激光雷达组合的测量系统,用于完成对整机外形的测量任务。该系统包含空间系统定位、坐标系建立、站位划分以及点云密度分布方面的详细方案设计。通过对测量数据与理论模型进行对比和误差分析,验证了综合测量精度符合系统标称场控精度,进而验证了所提方法的可行性和正确性。Aircraft assembly parts are characterized by large size and complex shape,the deviation of the assembled dimensions from the theoretical model,and the huge amount of measurement data of the aircraft profile,so designing an efficient and accurate measurement method of the aircraft profile is crucial to ensure the accuracy of the aircraft assembly.A measurement system combining laser tracker and lidar is established to fulfill the measurement task of the whole aircraft profile.The system includes the detailed program design in terms of spatial system positioning,coordinate system establishment,stations division and point cloud density distribution.By comparing the measurement data with the theoretical model and analyzing the errors,it is verified that the integrated measurement accuracy conforms to the nominal field control accuracy of the system,which in turn verifies the feasibility and correctness of the proposed method.
