Abstract

The invention provides a method and a device for determining a phenological period of a crop. The method comprises the following steps: acquiring a target crop phenological curve of a target crop and a reference crop phenological curve corresponding to the target crop phenological curve; according to the reference crop phenological curve, performing waveform adjustment on the target crop phenological curve to obtain an adjusted target crop phenological curve; determining time alignment relationship information of the adjusted phenological curve of the target crop and the phenological curve of the reference crop; and determining the phenological period of the target crop according to the time alignment relationship information. According to the method, the phenological period of the target crop determined by using the target crop phenological curve of the target crop and the reference crop phenological curve corresponding to the target crop phenological curve is more accurate and has higher reference value, so that the problems of subjectivity, one-sidedness and limitation caused by manual evaluation according to experience are avoided; and the efficiency of determining the phenological period of the target crop is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method and device for determining the phenological period of crops. Background technique [0002] Accurate determination of crop phenology information is crucial for field management and decision-making. Crop phenology is an important link between crop ecosystem and yield estimation, so accurate determination of crop phenology is crucial for field management and decision-making. The traditional methods of crop phenology information extraction mainly use manual records and weather station observations. These methods are often accompanied by disadvantages such as high cost and long time consumption, resulting in low extraction efficiency of crop phenology information, and are not suitable for large-scale acquisition of crop phenology information. . At the same time, due to the influence of latitude and climate factors, it is also difficult to directly extend the crop phen...
