【摘要】：针对航空影像中电力线匹配与三维建模的不确定性,该文提出一种基于圆形度约束的电力线匹配策略和基于悬链方程的电力线三维建模方法。基于电力线分裂导线分布特征,采用圆形度约束的条件,实现由计算机自动确定同相内同名线段;采用架空线悬链方程,实现了高效、可靠的电力线三维建模。实验证明,该文提出的方法能够高效还原电力走廊中电力线的空间位置,适用于基于影像的电力巡线和电力线建模,及电力走廊三维重建等领域。
[Abstract]:Aiming at the uncertainty of power line matching and 3D modeling in aeronautical images, this paper presents a power line matching strategy based on circularity constraint and a power line 3D modeling method based on catenary equation. By using the condition of roundness constraint, the computer can automatically determine the line segment of the same name in the same phase, and the overhead catenary equation is used to realize the efficient and reliable 3D modeling of power line. The method proposed in this paper can efficiently restore the spatial position of power lines in power corridors, and is suitable for image-based power inspection and power line modeling, and 3D reconstruction of power corridors.
