低空遥感光谱采集装置设计

摘 要

我国森林广阔，是我国经济生产的重要因素，而每年因为病虫害造成的经济损失多达上千亿元，因此对林业病虫害的检测就显得尤为重要。由于采集标本和地面、航空、卫星遥感检测林业病虫害的的方法受到诸多限制，加上如今无人机技术的飞速发展，因此可以将小型无人机平台和植被光谱采集装置结合起来，设计搭建多旋翼无人机机体，设计飞控，设计航拍云台，选定相机，进行光谱应用改装。通过对林业作物区域进行低空航拍，并对航拍光谱图像进行光谱分析和病情诊断，达到方便快捷、低成本并且能够对大面积的林业作物进行即时重复地分析检测的目的。

Design of spectral acquisition device based on UAV

ABSTRACT

Our country forest is broad,it is the main factor of economic production of our country,and the economic loss that causes because of disease and insect pest every year amounts to hundreds of billions of yuan,because this is right,the detection of forestry disease and insect pest appears particularly important.Because the samples were taken and the ground,aviation,satellite remote sensing detection method is limited by many forestry pests and diseases,with the rapid development of unmanned aerial vehicle(uav)technology nowadays,therefore can be small unmanned aerial vehicle(uav)platform and vegetation spectral acquisition device,designed to build more drones lead-lag and flight control design,design of aerial yuntai,camera,selected for the application of modified.By taking aerial photographs of forest crop areas at low altitude and making spectral analysis and disease diagnosis of aerial photographs,it is convenient,fast,low-cost and able to conduct real-time and repeated analysis and detection of large areas of forest crops.
