Abstract

The invention discloses a method and a device for dynamically updating sugarcane planting information. The method comprises the following specific steps: acquiring high-resolution remote sensing images of sugarcane plots in the same region at different time phases, and identifying unchangeable plots and changeable plots; performing time dimension migration on the unchangeable plots by utilizing historical land properties; timely performing characteristic matching on the changeable plots and the unchangeable plots, and identifying sugarcane plots and non-sugarcane plots in the changeable plots. By the method, high-resolution data are used as a basis for identifying and classifying the plots, so that a phenomenon of 'salt and pepper' in pixel-class classification is avoided, and the classification accuracy, the area measurement accuracy and the result verifiability are improved; the conventional object-oriented irregular mode spots without natural and social attribute significances are replaced by a precise plot boundary; the updating rate and the updating frequency of the sugarcane planting information are improved, and the dependency on the data amount in the updating process is reduced.

Description

technical field [0001] The invention relates to the field of sugarcane planting support, in particular to a method and device for dynamically updating sugarcane planting information. Background technique [0002] Remote sensing (RS Remote Sensing) technology has the advantages of macroscopic, rapid and repeated observation, and is widely used in environmental protection and resource investigation of land, water conservancy, forestry and agriculture. Compared with other methods, RS Remote Sensing technology can obtain different time resolution and Large-scale surface information at spatial resolution and abundant remote sensing satellite image data sources provide data support for the dynamic change information of the environment and resources on the earth. It has incomparable advantages in dynamic monitoring and updating of crop planting area. [0003] The most common remote sensing monitoring methods for planting information can be basically divided into two types: pixel-to...
