地面多角度农业遥感观测装置设计与试验

Design and Experiment of Ground-based Agriculture-oriented Multi-angle Observation Device

摘要:

针对现有多角度对地观测设备存在机动性差、操作周期长、无法搭载较重仪器等问题，设计了一种面向作物信息快速获取的地面多角度农业遥感观测装置(GAMOD)及信息采集控制系统，利用该装置同步搭载高清相机和可见-近红外成像光谱仪（VNIHS）进行大田观测，耗时10min（所需时间由观测角度决定）可快速获取太阳主平面（0°、180°）和垂直太阳主平面（90°、270°）下4个观测天顶角（0°、20°、40°、60°）的大豆植被影像数据。结果表明：该装置及控制软件运行良好，在多角度观测方式支持下，能有效捕捉到大豆植被三维立体的结构信息。

Abstract:

Currently, most existing multi-angular earth observation equipments are inflexible, have long operation time and light pay-load capacities. To overcome the limitations mentioned above, the ground-based agriculture-oriented multi-angle observation device (GAMOD), oriented to fast acquire crop multi-angular data, was designed. The GAMOD was tested in a soybean field with visible/near-infrared imaging hyperspectral spectrometer (VNIHS) mounted on. It takes 10min to acquire multi-angular data at four view zenith angles of 0°, 20°, 40° and 60°, under azimuth angles of 0°, 90°, 180° and 270°, respectively. As a result, 3-D structure information of soybean group can be effectively captured by supporting of multi-angular observation.
