The invention provides a
cultivated land identification method,
system and device based on
modal fusion and a medium, and belongs to the technical field of
cultivated land identification. The method comprises the following steps: acquiring image data of to-be-identified
cultivated land through an unmanned aerial vehicle, and acquiring GIS vector data and historical
time sequence images of the to-be-identified cultivated land to form a basic
data set; performing correction, splicing and segmentation
processing on image data in the basic
data set, performing unified coordinate
system processing on GIS vector data in the basic
data set, and calculating field piece regularity;
processing the basic data set by using a single-mode
visual perception model, outputting a preliminary detection result containing a probability graph and boundary information, correcting the preliminary detection result by using a multi-mode
logical reasoning module in combination with auxiliary data, and generating an identification result; and carrying out
visualization and vectorization processing on the identification result to generate visual data, and displaying the visual data. According to the invention, through multi-
modal fusion and multi-dimensional processing, the precision and reliability of cultivated land identification are significantly improved.
