摘　　要：针对大型构件多传感系统协同测量中各系统测量可达性模型多样化、多系统测量精度不均衡而导致的组合式测量站位设置多依赖测量人员经验以及需要不断尝试获取合适站位的问题,提出一种多传感系统协同测量场的站位规划方法。首先,考虑工装遮挡问题,对协同测量场中的组合式测量可达性模型进行优化,建立基于?鱼优化算法的有工装站位初值求解模型,解算组合式测量系统各测量站位初始值;其次,建立协同测量精度模型,以测量精度最佳为约束条件,建立观测值的加权均方根误差和矢量角度测量误差的优化目标函数,基于牛顿迭代算法不断迭代和更新到最佳精度站位坐标;最后,以某目标模拟器满足位置、姿态初始装调精度需求为例,进行组合式协同测量站位规划实验,优化后测量数据均方根误差为0.032 mm,相较于优化前测量规划位置测量精度提高34%,角度测量精度提高9.5%。该方法可有效地提高测量精度及可视化效果,为大型构件测量领域的进一步研究提供理论及应用参考。With the continuous development and technological advances in the modern industrial field,large component measurement techniques are becoming increasingly important in various fields.Particularly in areas such as large machinery and equipment,aerospace,etc.,accurately measuring and evaluating the dimensions and shapes of parts,components,and systems is critical to ensuring product quality,meeting design requirements,and ensuring safety.Among them,station planning plays a key role in large component measurement tasks,and it directly affects the overall accuracy and efficiency of the entire measurement task.Currently,the station planning of large component measurement often relies on experienced surveyors,which leads to an increase in the time and labor cost of the measurement and the instability of the measurement results.Secondly,the traditional method of station planning for large component measurement is often time-consuming and inefficient,lacks theoretical basis and evaluation methods,and is prone to problems such as large number of stations,high number of station transfers and low measurement efficiency,which can not meet the needs of modern manufacturing industry for fast and efficient measurement.In view of the above-mentioned large-scale component multi-sensing system station planning,due to the diversification of system measurement accessibility models and the imbalance of multi-system measurement accuracy,the combined measurement station setting relies heavily on the experience of surveyors and continuous attempts to obtain suitable stations.To solve the problem,this paper proposes a combined measurement station planning method for multi-sensor systems.Firstly,considering the tooling occlusion issue,based on the combined measurement accessibility model in the collaborative measurement field,we establish an initial value solving model for tooling-affected station positions using the Remora optimization algorithm.This model calculates the initial values of measurement stations in the combined measurement
