摘要 针对低压架空线路空间环境复杂导致安全距离隐患排查难的问题,提出了一种自定义的直接线性变换方法(Direct Linear Transformation of Self-Calibration,DLTSC),集成到便携式装置来计算导线弧垂及与周围物体的空间距离。以激光测距仪和陀螺仪进行空间测距,根据成像原理及空间测距仪辅助自标定,获取4个虚拟控制点计算参数;通过空间测距仪实测控制点进行参数修正,完成对DLT的自标定;解决了传统方法需要实际部署控制点的问题,实现了低成本和便携式测量,测量误差范围也满足实际工程需求。 For the problem that the complex spatial environment of low-voltage overhead lines leads to the difficulty of safety distance hidden troubleshooting,we propose the Direct Linear Transformation of Self-Calibration(DLTSC),integrated into a portable device to calculate the spatial distance of the wire sag and surrounding objects.We use laser rangefinder and gyroscope for spatial ranging.Four virtual control point calculation parameters are obtained according to the imaging principle and the spatial rangefinder-assisted selfcalibration.Complete the self-calibration of DLT by carrying out parameter correction through the measured control points of the space rangefinder.The proposed method solves the problem that the traditional method requires the actual deployment of control points,realizes low-cost and portable measurement,and the measurement error range also meets the actual engineering needs.
