卫星图像可从太空视角观测地球表面云层与下垫面特征，静止气象卫星云图凭借其广视角及高时效观测能力，可实时动态呈现台风云系的初生、发展与移动轨迹。然而，现有台风可视化跟踪多基于二维平面云图，展现方式单一，难以满足后续研究对台风精细结构解析的需求。为此，文章采用三维重构技术，结合风云四号A星的云顶高度反演产品数据，将二维卫星图像快速转化为立体台风云系模型。所提出的方法有效突破了传统卫星云图的平面渲染局限性，支持从任意视角立体观察台风云层与云系的形态特征，并可集成多时次图像生成动态三维云图动画，以直观呈现台风演变过程。以2022—2023年20余个强台风为案例的实验表明，使用所提出的方法可成功且有效实现台风云系的高效三维重构。

Satellite images observes cloud cover and underlying surface features of the Earth from a space perspective.Geostationary meteorological satellite cloud images,leveraging their broad coverage and high-temporal-resolution observation capability,enable dynamic visualization of the initiation,development,and trajectory of typhoon cloud systems in near real-time.However,existing typhoon tracking visualizations are predominantly based on two-dimensional cloud images,which offers limited presentation method and struggles to meet the demands of subsequent research for detailed structural analysis of typhoons.To address this limitation,this study employs three-dimensional reconstruction technology,integrating Fengyun-4 Asatellitederived cloud-top height retrieval products to rapidly transform two-dimensional satellite images into stereoscopic typhoon cloud system patterns.The proposed method effectively overcomes the planar rendering constraints of traditional satellite cloud images,allowing for stereoscopic observation morphological features of typhoon cloud layers and cloud systems from arbitrary viewpoints.It can also integrate multi-temporal images to generate dynamic three-dimensional cloud animations,providing an intuitive presentation of the typhoon's development process.Experimental results involving over 20 strong typhoons from 2022 to 2023 demonstrate the successful and efficient three-dimensional reconstruction of typhoon cloud systems using the proposed method.
