潜艇建造中的全站仪高精度转站方法

High accuracy station moving method for total station in submarine construction

  • 摘要:
      目的  应用全站仪对潜艇总段耐压壳体进行测量时,由于壳体分层、结构物遮挡等原因,需在多个不同位置架设全站仪才能完成整个舱段的测量,而全站仪自身转站功能限制条件大,无法满足潜艇内部测量的复杂环境要求,也难以保证较好的总体测量精度,因此提出一种新的高精度转站方法。
      方法  该方法是在不同站位下均测量设定的几个相同公共点,利用各站位下的公共点坐标设计算法,自动建立多级转站关系,
      结果  有效提高了转站精度和测量效率。
      结论  实验表明,所提方法在多级转站条件下仍能保证总体测量达到亚毫米精度,可以满足潜艇建造的高精度测量要求。

     

    Abstract:
      Objectives  When we measure submarine pressure hulls using a total station, it is essential to set several stations in order to complete the measurement of the whole cabin due to the complicated measuring environment. However, there are many restrictions related to the total station itself when moving stations, and it is also difficult to ensure measuring accuracy and satisfy the requirements of submarine measurement in complicated environments.
      Methods  As such, a new station moving method is presented which can automatically establish standing relationships by measuring common points at every measuring position.
      Results  This method can significantly improve accuracy and efficiency.
      Conclusions  The experiment shows that the results of the new station moving method can meet sub-pixel precision and satisfy submarine measurement requirements with high accuracy.
