一种基于微型惯导陀螺仪的运行电力管线三维轨迹测量方法及系统

本发明公开了一种基于微型惯导陀螺仪的运行电力管线三维轨迹测量方法及系统，属于电力管线运维与地下空间探测技术领域。该方法将搭载微型惯导陀螺仪的内穿测量装置置入运行电力管线管口，完成初始姿态校准后驱动装置匀速居中穿行，穿行过程中采集惯性原始数据并同步进行工频电磁噪声预处理，经捷联惯导解算得到装置运动坐标序列，再结合电力管线起止端基准坐标进行整体平差校正，拟合生成高精度三维轨迹。该系统包括数据采集模块与数据处理模块，内置工频预处理单元与基准校正单元，适配带电运行电力管线的特殊工况。本发明可在非开挖、不停电条件下完成测量，有效抑制工频干扰与惯导累积漂移，测量精度与场景适配性显著提升。
