| Abstract: | The construction of a smart subway requires the support of a three-dimensional model. The use of oblique photography technology combined with advanced three-dimensional visualization technology to construct a three-dimensional model provides data support for the smart subway, and promotes the full development of the whole life cycle of smart subway construction. This article aims to use the R1 line of urban rail transit in Xiong'an new district as the research area, a drone flight is carried out for 85 kilometers along the R1 line, a 3D real-world model of the line is obtained through processing, and the accuracy of the results is compared in detail. The results show that the results of the tilt photogrammetry met 1:500 scale requirement. In addition, the application of oblique photogrammetry technology in urban rail transit construction is introduced, which opened up a new direction for the transformation of urban rail transit construction from two-dimensional to three-dimensional. |
