The invention belongs to the technical field of
remote sensing image processing agricultural information, and particularly relates to a DS-xNet-based multi-source
remote sensing time sequence data
cultivated land utilization current situation extraction method. According to the method, the
cultivated land and the
water body can still be reliably recognized under the cloud or
fog condition by combining Sentinel-1 and Sentinel-2, missing detection and misjudgment caused by cloud shielding are reduced, sNET captures short-term dynamic conditions, and mNET matrix memory enhances long-term dependence modeling, so that the recognition precision of seasonal and interannual changes is improved, supervision is applied to a
branch and fusion layer, and the recognition accuracy of the
cultivated land and the
water body is improved. According to the method, each
branch can learn independent discrimination capability and can cooperatively improve fusion output, over-fitting is reduced, generalization capability is improved, training convergence is accelerated, channel splicing retains discrimination information of each
modal in a fusion stage,
modal information conflict or loss caused by direct early fusion is avoided, classification accuracy is improved, and classification efficiency is improved. Various optical and
radar indexes are combined and used to enhance the distinguishing capability of paddy fields,
irrigation areas, different crops and non-cultivated areas.
