    摘要:

    針對現(xiàn)有多角度對地觀測設備存在機動性差、操作周期長、無法搭載較重儀器等問題,設計了一種面向作物信息快速獲取的地面多角度農業(yè)遙感觀測裝置(GAMOD)及信息采集控制系統(tǒng),利用該裝置同步搭載高清相機和可見-近紅外成像光譜儀(VNIHS)進行大田觀測,耗時10min(所需時間由觀測角度決定)可快速獲取太陽主平面(0°、180°)和垂直太陽主平面(90°、270°)下4個觀測天頂角(0°、20°、40°、60°)的大豆植被影像數(shù)據(jù)。結果表明:該裝置及控制軟件運行良好,在多角度觀測方式支持下,能有效捕捉到大豆植被三維立體的結構信息。

    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.
