[0067] The feature extraction module extracts features from the processed data, such as common features like plant size and leaf density, as well as abnormal features like localized yellowing of plant leaves and localized curling of plant parts.

[0068] The model management module initially establishes a correlation model between SPAC factors and plant phenotypes based on the extracted features. This model should reflect the influence of various environmental factors on various plant characteristics. Each factor should be assigned a correlation weight, and the factors with larger correlation weights have more significant effects.

[0069] The extrapolation module extrapolates future trends in plant phenotypic changes based on the established correlation model and real-time collected SPAC factor data.

[0070] The data evaluation module assesses the accuracy of the simulation module and provides feedback to the model management module. The model management module then dynamically adjusts the correlation weights of each factor in the correlation model based on the accuracy.

[0074] The data processing module includes:

[0075] The image data processing submodule preprocesses the acquired raw images, including denoising and contrast enhancement, to improve image quality and clarity. It also employs an image segmentation algorithm to separate the plants from the background for subsequent extraction of plant phenotypic features. Furthermore, it performs morphological processing on the segmented plant images, such as dilation and erosion, to fill small holes in the image, remove noise such as burrs, and obtain clearer plant image outlines.

[0076] The SPAC factor data processing submodule removes outliers and erroneous data from the collected SPAC factor data according to a set range; for example, the collected data is arranged along a time axis and labeled C1, C2, ..., C... n The entire data exhibits a linear variation; if at a certain moment C... i The value compared to C i-1 C i+1 There is a significant change, namely C i ≥[(C i-1 +C i+1 ) / 2]×(1+X)%, or C i <[(C i-1 +C i+1If ) / 2]×(1-X)%, where X is a set value, then it is considered an abnormal value, and the C i Delete, or remove C i The value is replaced with (C) i-1 +C i+1 ) / 2.

Specifically, for localized yellowing of leaves, a threshold range for yellowing is set in the RGB color space of the image. The yellowed areas are identified by judging the RGB values ​​of each pixel. The proportion of the yellowed area to the total leaf area is calculated as an indicator describing the abnormal feature of localized yellowing of leaves. For localized curling of plants, the curvature changes in the plant area are detected by analyzing the contour curve of the plant image. When the curvature exceeds a set threshold, curling is determined to exist in that area. The area, perimeter, maximum curling curvature, and average curling curvature of the curled area are calculated to quantify the abnormal feature of localized curling of plants.

It substitutes the real-time SPAC factor data into the model equation to calculate the predicted values ​​of plant phenotypic characteristics at future times. Where t is the current time and k is the prediction time step; confidence intervals are introduced to evaluate the reliability of the prediction results; and the standard error of the prediction value is calculated. Determine the confidence interval for the predicted value:

[0095] The scenario analysis submodule simulates the changes in plant phenotypes under different SPAC factor change scenarios set by the user, such as changes in soil moisture and temperature, based on the correlation model.

[0096] By setting up a scenario analysis submodule, researchers and agricultural producers can understand the impact of different environmental factors on plant growth, so as to better formulate reasonable cultivation and management measures.

[0097] The data evaluation module includes:

[0098] The accuracy assessment submodule compares the prediction results from the inference module with the actual observed plant phenotypic data to calculate the prediction accuracy (ACC). The formula for calculating the prediction accuracy is as follows:
