    • Monocular vision transmission line sag measurement method based on local photography

    • “输电线路弧垂测量领域迎来新的突破。传统的弧垂测量方法操作繁琐且耗时，而单目视觉方法又受限于视场角和分辨率，难以应对大档距输电线路的测量挑战。针对这一问题，研究人员提出了一种结合IMU加速度计传感器和高分辨率工业单目相机的局部摄影测量方法。在已知少量输电线路参数的前提下，只需拍摄待测导线的左侧部分，即可通过引入语义分割技术提取图像中的导线，建立摄影测量模型，进而恢复导线的三维形状并计算弧垂。这一方法不仅操作便捷，而且测量精度较高，相对误差可控制在5%以内，为输电线路弧垂测量提供了新的解决方案，对于保障输电线路的稳定运行具有重要意义。”
