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.
