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 10 min 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.%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10 min(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.
