Surveying railway special grid (sRSG) pins were integrated with terrestrial laser scanning (TLS) targets and near-field communication to develop an optimised and universal surveying sign that can be used to mount surveying prisms or adapters with prisms. The developed sRSG TLS signs can be used to define the X, Y, and H coordinates and adjustment data for the axes of tracks and turnouts, which can be collected and shared with smartphones. Three types of TLS targets were considered for the optimised sign. The developed sRSG TLS sign will allow remote identification and data transmission solutions to be adopted that facilitate surveying and diagnostic work. The results of this study demonstrated the practicality and usefulness of the integrated sRSG TLS sign.

测量铁路专用栅格（sRSG）引脚与地面激光扫描（TLS）目标和近场通信集成在一起，从而开发出一种优化的通用测量标志，可用于安装测量棱镜或带有棱镜的适配器。开发的sRSG TLS标志可用于定义轨道，道岔轴线的X，Y和H坐标以及调整数据，这些数据可以收集并与智能手机共享。优化符号考虑了三种类型的TLS目标。开发出的sRSG TLS标志将允许采用远程识别和数据传输解决方案，以方便勘测和诊断工作。这项研究的结果证明了集成的sRSG TLS标志的实用性和实用性。
