Abstract
This paper introduces several methods of aerial transmission line model construction: based on two-dimensional drawing modeling, based on laser scanning modeling, based on aerial modeling. And the results show that the efficiency of the design drawing method and the fineness of the model are high, but the data volume is large, which is not conducive to the management of the system. It is suitable for the new route. The efficiency of the construction drawing method Low precision, data is difficult to obtain, the accuracy can not be guaranteed, suitable for early construction and complete data lines; based on laser radar modeling accuracy and model of high precision, but the work of large strength, high cost, suitable for small area, High-level plain lines and substations; aerial modeling method can be used to make existing channel corridor channel and line ontology three-dimensional model data, high efficiency and accuracy, to meet the needs of operation and maintenance management, but also as a line clearance analysis And other deep application of the first-hand analysis of data, it is worth promoting the application.
