Edge-Cloud Collaborative Satellite Image Analysis for Efficient Man-Made Structure Recognition
Year: 2025
Type: conference-paper
Abstract: The increasing availability of high-resolution satellite imagery has created immense opportunities for various applications. However, processing and analyzing such vast amounts of data in a timely and accurate manner poses significant challenges. The paper presents a new satellite image processing architecture based on edge-cloud collaboration to better identify man-made structures against natural landscapes. By employing lightweight models at the edge, the system initially identifies potential man-made structures from all captured satellite imagery. These identified images are then transmitted to the cloud, where a more complex model refines the classification, determining specific types of structures. The primary focus is on reducing latency and improving accuracy, as the current system experiences delays, and many efficient models often compromise accuracy. We compare this hybrid edge-cloud approach against traditional "bent-pipe" method in virtual environment experiments as well as introduce a practical model, MSNET. We compare its performance with existing lightweight models for edge deployment focusing on accuracy and latency. The results demonstrate that the edge-cloud collaborative model not only reduces overall latency due to minimized data transmission but also maintains high accuracy, offering substantial improvements over traditional approaches under this scenario.
