This application provides a method, apparatus, and terminal device for
crop yield prediction, applicable to the field of
data processing technology. The method includes: generating first-modality
crop growth feature information and second-modality
crop growth feature information based on first-modality and second-modality crop image information; aligning and classifying the first-modality and second-modality
crop growth feature information to obtain
crop growth area information; and calculating
crop yield prediction information based on
crop yield prediction weight information,
crop yield prediction offset information, crop yield prediction weight correction step distance information, crop yield prediction offset correction step distance information, and
crop growth area information. This application comprehensively captures the spatiotemporal dynamics of crop growth from different observation modalities, eliminates the interference of spatiotemporal differences on prediction, dynamically adjusts prediction parameters to improve crop yield prediction accuracy, and effectively enhances the precision of farmland management and the rationality of
resource allocation.
