| 摘 要： | 介绍了基于二维图纸建模，激光扫描建模和航测建模架空输电线路模型构建的几种方法，并做了详细的对比分析，结果表明:利用设计图纸建模法效率和模型精细度较高，但是数据量较大，不利于系统的管理，适用于新建线路；利用施竣工图纸建模法效率低下，资料较难获取，精度无法保证，适用于早期修建且资料完整的线路；基于激光雷达建模法精度和模型精细度较高，但是作业强度大、成本高，适用于小面积、精度要求较高的平原地区线路及变电站；基于航测建模法可以制作已有线路走廊通道和线路本体三维模型数据，效率和精度较高，可以满足运维管理的需求，同时也可作为线路净空距离分析等各种深化应用分析的第一手数据，值得推广应用。

| 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. |
