油电混合多旋翼无人机技术在铁路勘测中的应用

Application of Oil-electric Hybrid Multi-rotary Wing Unmanned Aerial Vehicle Technology in Railway Survey

针对现有无人机技术航时短、精度差、空中俯视效果差等地形测绘问题,提出了一套高航时、高精度、易携带、易操作的油电混合新型旋翼无人机航测系统。该系统可以获得高分辨率遥感影像和高精度线路测量数据,弥补了人员不易抵达区段的勘测缺陷。测试结果表明,该系统距离测量相对误差小于5%,测量精度较高。

With regard to the existing problems of unmanned aerial vehicle(UVA)technology for topographic surveying,such as short flight time,poor accuracy and poor aerial view effect,this paper proposes a new type of oil-electric hybrid rotary wing UAV aerial survey system with high flight time,high precision,easy portability and easy operation.The system can obtain remote sensing images with high resolution and line measurement data with high accuracy,it is able to compensate for the survey of the section to which personnel are not easy to reach.The test results show that the relative error for measurement of distance is less than 5%,and the measurement accuracy is higher.
