| 摘 要： | 经纬仪测量设备能够获取卫星及星上仪器设备安装的角度和位置等精测数据,而从测量数据本身不易直观分析出航天器壳体结构和星上设备安装的精度。为此设计了一种基于Unity的航天器精测数据可视化模型——U-SAM。本文在分析目前航天器精测数据可视化存在问题的基础上;重点阐述和论证结合立方镜准直测量原理设计U-SAM可视化模型的方法;并测试了基于U-SAM模型的可视化效果。结果表明,基于该模型对测量数据可视化能够形象、直观、快速地反映测量数据目前具有的或在随后的测量过程中可能出现的误差趋势,从而指导工作人员对设备总装、测量手段等进行不断地调整和优化。该模型能够高效地对测量数据进行诊断,检测测量数据的正确性和有效性为航空航天部门提供技术支持,减轻测量工作强度,提高工作效率。

| Abstract: | Electronic theodolite measuring equipment could obtain the installation angle and position of satellite and onboard equipment, with which the installing accuracy of spacecraft shell structure and equipments on satellites couldn' t be analyzed directly. U-SAM, a visualization model of spacecraft accurate measurement data based on U-nity is designed. On the base of analyzing existing problems of visualization for spacecraft accurate measurement data, It is mainly set forth and demonstrated how to design U-SAM model with collimating measuring theory of cube mirror, and the visual effect is tested. The experimental results indicate that U-SAM model can reflect error trends at present or in subsequent measurement process vividly, intuitively and quickly, which can guide the staff to ad-just or optimize equipment assembly and measuring means continuously. U-SAM model can be used to detect the correctness and validity of measurement data, to provide technical support for spacecraft departments, to reduce work intensity of measuring and to improve work efficiency. |
