Embodiment 1

[0045] Such as Figure 6 As shown, a method for determining the growth area of ​​Nandi is disclosed in this implementation, comprising the following steps:

[0046] According to the difference between the spectral characteristic data of Nandi and other vegetation in different periods in the area to be monitored, determine the optimal monitoring phase of Nandi in the area to be monitored and its corresponding spectral feature threshold; different periods correspond to Nandi and other vegetation. growth stage;

[0047]Obtain the spectral feature data of each sub-area in the optimal monitoring phase in the area to be monitored, and compare the spectral feature data of each sub-area with the spectral feature threshold. When there is any sub-area with spectral feature data within the spectral feature threshold, Then it is judged that the sub-area is the growth area of ​​Nandi.

[0048] In addition, in this embodiment, a method for segmenting the growth area of ​​Nandi is also dis...

Embodiment 2

[0055] Embodiment two is a preferred embodiment of embodiment one, and its difference from embodiment one is that the specific steps of the determination of the growth area of ​​Nandi in the present invention and the segmentation method are refined:

Abstract

The invention discloses a triarrhena lutarioriparia growth region determination method, a triarrhena lutarioriparia growth region segmentation method, and a system. The triarrhena lutarioriparia growth region determination method comprises the following steps: determining an optimal monitoring time phase of triarrhena lutarioriparia in a to-be-monitored region and a corresponding spectral feature threshold according to the difference between spectral feature data of the triarrhena lutarioriparia and spectral feature data of other vegetation in different periods in the to-be-monitored region; enabling different stages to correspond to different growth stages of the triarrhena lutarioriparia and other vegetation; and acquiring spectral feature data of each sub-region in the to-be-monitored region at the optimal monitoring time phase, comparing the spectral feature data of each sub-region with a spectral feature threshold value, and judging that the sub-region is a triarrhena lutarioriparia growth region when the spectral feature data of any sub-region is within the spectral feature threshold value. Compared with the prior art, the invention has the advantages that the triarrhena lutarioriparia and other vegetation in the to-be-monitored area can be distinguished by utilizing the spectral characteristics of the triarrhena lutarioriparia in different growth stages, so that the distribution condition of the triarrhena lutarioriparia in the to-be-monitored.
