Application of 3D scanning technology in the construction of transmission line cross-spanning

Cross crossing survey is a key work in transmission line construction. The accuracy of survey results directly affects the construction quality of transmission line cross crossing. Three-dimensional scanning technology can convert the three-dimensional information of the physical object into digital signals that can be directly processed by the computer, which provides a very convenient and fast means for the digitization of the physical object. Therefore, this paper uses three-dimensional scanning technology and combined with the characteristics of transmission lines, the cross crossing construction method of transmission lines is optimized. The point cloud data in the transmission line construction environment is obtained by using three-dimensional scanning technology, and the crossing distance of transmission lines is measured. Through the application effect test experiment, it is concluded that the ranging error of three-dimensional scanning technology in the construction environment is O.14m, which is lower than the preset value. Through the application of three-dimensional scanning technology, the construction qualification rate of transmission line connection point is improved, and the voltage fluctuation coefficient of transmission line is reduced, that is, the construction quality of transmission line crossing is improved.
