Discussion on Three-dimensional Design of Overhead Transmission Line Based on Tilt Photogrammetry Technolog

Abstract

With the rapid development of modern social economy, the continuous expansion of urban land and the increasing scale of power system construction, there are many problems in cable transmission and routing in overhead transmission lines. This paper mainly introduces the tilt photogrammetry technology, and studies its application in the three-dimensional design of overhead transmission lines. Firstly, this paper introduces the concept, basic principle and key technology of tilt photogrammetry technology, expounds the importance of three-dimensional design of overhead transmission line, and then tests the error value of three-dimensional software of overhead transmission line. Finally, the test results show that the maximum plane error is 0.253 m and the mean square error is 0.168 M. The maximum error of elevation is 0.247m and the mean square error of elevation is 0.128 M. Its accuracy shall meet the requirements that the error shall not exceed 0.2m and the mean square error of elevation shall not exceed 0.2m.
