The invention relates to the technical field of
data analysis, in particular to a
plant state evaluation method and
system based on a multi-
modal thinking chain technology, and the method comprises the steps: firstly obtaining a
plant disease image, a
disease description text, an environment parameter and a target
crop type, and then associating the target
crop type with the
disease description text; the method comprises the following steps: acquiring a
plant disease image, inputting associated data into a pre-trained
language model, calculating semantic features of a
disease description text, inputting the
plant disease image and environmental parameters into a preset
reinforcement learning and
interpretability enhancement model, respectively calculating to obtain an
image quality score and a
pathological constraint reward parameter of the
plant disease image, and finally, obtaining the
image quality score and the
pathological constraint reward parameter of the
plant disease image. And inputting the
pathological constraint reward parameters, the
image quality score and the semantic features into a preset multi-
modal thinking chain reasoning model, and calculating to obtain an
evaluation result of the plant disease image. Compared with the prior art, the
evaluation result of the method is more accurate.
