一种冬小麦种植比例的计算方法及装置
摘要：
本发明实施例提供一种冬小麦种植比例的计算方法及装置。所述方法包括：根据近红外波段的反射率和红光波段的反射率获取研究区域内各时相的归一化植被指数；对各时相的归一化植被指数进行叠加得到对应的归一化植被指数集，提取所述归一化植被指数集中纯冬小麦的归一化植被指数集和非冬小麦对应的归一化植被指数集；根据所述纯冬小麦的归一化植被指数集得到纯冬小麦的时间序列曲线，并根据所述非冬小麦对应的归一化植被指数集得到非冬小麦对应的时间序列曲线；根据所述纯冬小麦的时间序列曲线和非冬小麦对应的时间序列曲线，计算获得所述研究区域内冬小麦的种植比例。本发明实现了利用植被指数简易高效准确地获得冬小麦的种植比例。
摘要（英）：

The invention provides a winter wheat planting proportion calculation method and a winter wheat planting proportion calculation device. The winter wheat planting proportion calculation method comprises steps that according to reflectivity of a near infrared band and reflectivity of a red light band, normalization vegetation indexes of various time phases in a study area are acquired; the normalization vegetation indexes of the various time phases are superposed together to acquire a corresponding normalization vegetation index set, and the normalization vegetation index set of the pure winter wheat and the normalization vegetation index set corresponding to the non-winter wheat of the normalization vegetation index set are extracted; according to the normalization vegetation index set of the pure winter wheat, the time sequence curve of the pure winter wheat is acquired, and according to the normalization vegetation index set corresponding to the non-winter wheat, the time sequence curve corresponding to the non-winter wheat is acquired; according to the time sequence curve of the pure winter wheat and the time sequence curve of the non-winter wheat, the winter wheat planting proportion in the study area is calculated. By using the vegetation indexes, the winter wheat planting proportion is acquired simply, effectively, and accurately.
