This invention relates to an optimized method for single-fruit harvesting in orchards based on multimodal data fusion. It involves simultaneously acquiring image information of the fruit, local environmental data, and tree physiological indicators using multimodal sensors, and preprocessing these data. Taking into account the heterogeneous nature of different modalities, independent feature extraction networks are used to obtain deep features for each modality, constructing a heterogeneous modal deep fusion network. A cross-domain attention mechanism dynamically integrates these features, effectively capturing the complex correlations affecting fruit maturity and generating fused features. Based on these features, the model can predict the real-time maturity of individual fruits. Combining external conditions, a multi-objective optimization algorithm is used to calculate the harvesting priority score for each fruit, generating an executable harvesting sequence to guide robots or manual harvesting in an orderly manner. This invention significantly improves the accuracy of maturity prediction and the overall efficiency of harvesting operations, providing effective support for refined management and intelligent operation in orchards.
