摘要
为了提高无人机电力线路巡检效率,在分析双目视觉测距以及双目相机标定的基础上,建立了基于双目测距的无人机电力线路巡检安全距离测量方案,并采用双目测距原理搭建试验台对建立的系统进行实拍图像的Hough直线测试。研究结果表明模拟和输电线相距15米的部位测距时,在无人机上搭载双目测距仪,通过对比发现测试距离接近实际15米,误差被控制于5%范围内。利用无人机搭载双目测距仪,控制赶超非常灵活,当无人机飞行期间受到气流干扰后云台角度将发生变化。
In order to improve the safe distance measurement accuracy for unmanned aerial vehicle(UAV)power line inspection,based on the analysis of binocular vision range and binocular camera calibration,safe distance measurement for power line inspection scheme of UAV binocular distance measurement is established.The binocular distance measurement principle is used to build test bench to set up the system of film image by Hough line test.The results show when the distance between the simulation and the power line is 15 m,the test distance of UAV which is equipped with a binocular rangefinder is close to 15 m and the error is controlled within 5%.The UAV is very flexible in controlling catching up.When the UAV is disturbed by airflow during flight,the head angle will be changed.
