叶片及冠层尺度 Leaf and canopy scale | 非成像高光谱扫描仪、成像高光谱仪。 Non-imaging hyperspectral scanner and imaging hyperspectral spectrometer. | 方便、灵活以及受外界因素影响较小、监测精度高, 通常用于作物病害的遥感探测机理研究, 受探测范围限制, 难以实现大区域作物病害的遥感探测。 Convenient, flexible and less affected by external factors, with high detection accuracy. It is usually used to study the mechanism of early warning and detection of crop diseases. Due to the limitation of the detection range, it is difficult to realize the correction and detection of large-area crop diseases. | 甜菜叶斑病、叶锈病和白粉病 Sugar beet leaf spot, leaf rust and powdery mildew | [66] |
