High accuracy station moving method for total station in submarine construction

  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.
