摘要
采用输电线路交叉跨越的三维计算模型,对导、地线跨越高速铁路、高速公路及输电线路的情况做三维场景模型建立,为准确定位交叉跨越点,计算交叉跨越距离,建立了输电线路交叉跨越三维计算模型。通过实际校核导线与高速铁路及高速公路的水平、垂直和净空距离,验证了模型的准确性和实用性,为交叉跨越距离测量和在线监测系统提供了可靠的算法支持。
Three-dimensional computing model that is crossed by transmission lines,the three-dimensional model is established for traverse high-speed railway, expressway and transmission lines, crossing points for accurate positioning,calculate cross-crossing distances,establish a cross-crossing model of transmission lines.The horizontal, vertical and clearance distance between the actual check lead and the high speed rail and the highway,verified by the model of the accuracy and practicability, it provides reliable algorithm support for cross-span measurement and on-line monitoring system,
