Application of a Semi-automatic Connection Measurement Method
In the connection measurement of urban rail transit engineering,the traditional manual connection measurement methods have some drawbacks,such as low work efficiency and easy errors.Through practical research and analysis,this paper proposed a semi-automatic connection measurement method.Based on the"TSDI Multi-observation"airborne software,combined with the Leica total station and the traditional wire-steel method for manual connection measurement,the measurement and data recording were completed through the automatic positioning of the instrument,and then semi-automatic connection measurement was completed.At the same time,utilizing self-designed post-processing software,the data of traverse survey were checked,analyzed,and finally generated,which could be used for rigorous adjustment.A fast and effective method for obtaining high-quality connection measurement results was presented.Using the method in this paper,only 2 surveyors were needed to complete a set of shaft connection survey work,and all the survey work could be completed within 1 hour.Compared to traditional manual measurement,this method improves measurement efficiency by nearly four times,reduces the number of measurement personnel by nearly half,and avoids disadvantages of manual recording errors.
