摘要

With the recent development of remote sensing (RS) technology, the amount of RS platforms has witnessed a substantial increase, and the capacity of Earth observation has been greatly enhanced. The interpretation of RS images has also gradually evolved from traditional centralized ground processing to on-orbit processing. However, the traditional single-platform on-orbit processing is limited to a single source of information, which results in the underutilization of the advantages of multiplatform observation in the current RS field, and restricts the accuracy of inference tasks. To tackle the aforementioned problem, we propose a multiplatform distributed collaborative inference network, which can combine the intermediate features from multiple platforms to improve the accuracy of inference tasks. First, we proposed the collaboration map generator, which generates the collaboration map for optimal collaborator selection autonomously. Second, a spatial feature compression (SFC) module is designed to compress the interplatform transmission features, adapting spatially sparse distribution characteristics of RS objects. Finally, a feature fusion module containing spatial priors is proposed to fuse the features collected from multiple platforms to obtain more precise inference results. We conducted extensive experiments on three public datasets and verified the effectiveness of the proposed framework. On the NWPU VHR-10 dataset, for example, the proposed method improves the detection accuracy by 13.7% and 10.3% under two experimental settings compared with a single platform and compresses the intermediate data transmission between platforms by more than 80%.
