为了确定旋翼无人机的位置信息，设计了一种采用激光雷达UTM-30LX来获取无人机定位信息的检测系统。该系统采用了激光雷达作为机载传感器获取无人机的周围环境数据，并使用了树莓派2代B型开发板来处理相关数据和控制检测系统。系统软件设计方面，采用C语言和MATLAB语言进行数据预处理、坐标投影变换、位移估计和定位。此外，阐述了定位信息检测的原理、检测系统的硬件电路设计方案和系统软件设计方案等。最后的实验数据表明，设计方案能够满足获取无人机位置信息的需求。%In order to determine the position information of a rotor unmanned aerial vehicle (UAV), a kind of detection system based on the laser radar UTM-30LX is designed to obtain the position information of UAV. The system uses a laser radar as airborne sensors to acquire the data of the surroundings, and Raspberry Pi 2nd generation B-type is used to process the data and control the detection system. System software design is involved with C language and MATLAB language for data preprocessing, coordinate projection transformation and translation estimation and positioning. In addition, this paper describes the positioning information detection principle, hardware circuit design detection system and so on. Finally, the experimental data shows that the design can meet the needs of obtaining the location information of UAV.
