摘要
高压输电线的弧垂是线路设计和运行的重要指标,关系到线路的运行安全,必须控制在设计规定的范围内。输电线弧垂测量是国内外电力部门和研究机构的重点研究内容。基于无人机多角度采集序列航拍图像,光束平差法优化和建立立方体网格点阵模型,获得输电线在实体空间的线路参数,实现弧垂的测量。实验结果表明,该方法成本低、效率高、安全可靠,适合在复杂的地理条件下应用,测量精度也能满足监测需要。
The sag of high-voltage transmission line is an important index of line design and operation, which is related to the safety of line operation and must be controlled within the design range. Sag measurement of transmission lines is the key research target of power departments and research institutes at home and abroad. In this paper, based on multi-angle sequence aerial images acquired by unmanned aerial vehicle( UAV), optimization of bundle adjustment and establishment of cubic?grid?points model, the line parameters of transmission lines in solid space were obtained to measure the sag. The experimental results show that the method is low cost, high efficiency, safe and reliable, which is suitable for complex geographical conditions, and the measurement accuracy can also meet the monitoring requirements.
