基准转换标准器在多系统集成中的应用

使用经纬仪、激光跟踪仪进行协同测量时需要对不同测量系统的测量基准进行基准转换,传统基准转换手段较为繁琐耗时。针对此问题,设计了一种新型便携式基准转换标准器,该标准器由基准转换组件、转向组件和三脚架组成,通过基准板上的测量靶点及立方镜构建坐标系,实现基准转换。经验证:该标准器在不同姿态下的平均位置偏差小于0.01 mm,利用基准转换标准器验证了经纬仪系统定位孔中心点的测量偏差均小于0.06 mm,立方镜法矢量的平均绝对偏差小于0.0043°。结果表明,该标准器操作方便快捷,能够满足不同工况下经纬仪与激光跟踪仪协同测试的基准转换需求,具有应用推广价值。

Application of Datum Conversion Standard Board in Multi-system Integration Measurement

When using theodolite and laser tracker for collaborative measurement, it is necessary to convert the measurement datum of different measurement systems. The traditional method of datum conversion is cumbersome and time-consuming. To solve this problem, this paper proposes a new portable reference conversion standard board, which is composed of a reference conversion component, a steering component and a tripod. The reference conversion is realized through the coordinate system constructed by the measuring target on the reference plate and the cubic mirror. When the laser tracker is used to verify the average position deviation of the standard board in different attitudes, the result is less than 0.01 mm, when the reference conversion standard board is used to verify the measurement deviation of the center point of the positioning hole of the theodolite system, the result is less than 0.06 mm, and the average absolute deviation of the normal vector of the cube mirror is less than 0.0043 °.The operation of the standard board is convenient and fast, which can meet the needs of benchmark conversion of theodolite and laser tracker collaborative testing under various working conditions, and has the value of application and promotion.
