AI Technical Summary

Technical Problem

Existing technologies for crop disease identification suffer from large timestamp biases in multi-source data, low spatial overlap, large errors in sparse feature completion, and poor feature correlation, resulting in low accuracy in early lesion identification and difficulty in distinguishing similar diseases. Furthermore, they are poorly adaptable to facility agriculture environments.

Method used

The dynamic time warping algorithm is used to align timestamps and verify spatial overlap of multi-source data. A multi-attention weight interpolation model is constructed to complete sparse features. Features are then fused using a three-dimensional convolutional network and a deep neural network to generate a multi-channel three-dimensional feature tensor for disease classification and lesion localization.

Benefits of technology

It achieves high consistency of multi-source data in time and space, accurately completes sparse features, improves the sensitivity of early lesion identification and the ability to distinguish different disease types, and provides accurate three-dimensional positioning coordinates, providing reliable guidance for precision pesticide application in facility agriculture.
