摘要
设计并实现了一套基于轻小型直升无人机的高光谱遥感成像系统。该系统包括高光谱成像,采集存储,姿态和位置测量及地面监视控制等部分。在烟台和扬州分别进行了两次飞行实验,获取了高分辨率的高光谱数据。分析了该系统在无人机平台上工作的性能。对实验数据分析后,发现平台姿态和位置的变化对地物目标的光谱信息无明显的影响,但对几何特性有明显影响,实验中平台的振动导致图像在横向有4个像元的抖动。最后利用POS数据对图像数据进行了几何校正,并分析了校正误差的来源。
A set of hyperspectral imaging remote sensing instruments was designed and completed. The system included hyperspectral imaging subsystem, data acquired and storage subsystem, monitoring and controlling on ground subsystem and position and orientation subsystem. To validate the performance of this system, a serial of experiments had been made in Yantai and Yangzhou, high geometric resolution hyperspectral data was acquired. After analyzing the spectral characterization and geometric characterization of the acquired data, the results show that the position and orientation of unmanned helicopter have no distinct effect on spectral characterization, but the shake of motor of unmanned helicopter results in 4 pixels dither of the image in roll in the experiment. Finally, the geometric information of the hysperspectral data was corrected with the data of position and orientation subsystem and the error of the geometric correction was analyzed.
