摘要
针对以直升机为平台的激光雷达导线安全距离检测方案成本较高、不易操作等缺点,提出了一种基于相机的多旋翼无人机单目序列影像导线安全距离检测方法。方法以摄影测量学中的GPS辅助空中三角测量以及空间前方交会为基础,建立待检导线下方地物三维模型,并采用人机交互方式生成导线的弧垂模型,进而进行导线与地物的间距计算,根据设定的阈值判断间距是否符合规范。最后通过对比实验对所提检测方法进行了验证,实验结果表明,该检测方法能够有效地对待检导线进行安全距离检测。
Aiming at the disadvantages of high cost and difficult operation of the laser radar wire safety distance detection scheme based on helicopter,this paper proposes a security distance detection method of power line based on multi-rotor UAV with camera-based monocular sequence image.This method is based on the GPS-assisted aerial triangulation in the photogrammetry and the intersection of the space front,and establishes the three-dimensional model of the ground object under the conductor to be inspected,and adopts the human-computer interaction method to generate the sag model of the wire,and then,the distance between the wire and the ground object is calculated according to the set threshold to determine whether the spacing meets the specifications.Finally,the detection method proposed in this paper is verified by comparison experiments.The experimental results show that the detection method can effectively detect the safe distance of the tested power line.
