面向标准地图服务的卫星影像智能裁切与动态更新方法
Journal: Geological and Mineral Surveying and Mapping DOI: 10.12238/gmsm.v8i3.2193
Abstract
随着地理信息应用的不断发展,标准地图服务对卫星影像的需求日益增长。本文深入探讨了面向标准地图服务的卫星影像智能裁切与动态更新方法,结合多层级影像金字塔、辐射传输方程组等专利核心技术,构建了“语义识别-精准裁切-动态更新”的完整技术链路。通过语义分割实现目标地物智能识别,结合金字塔层级匹配与辐射校正优化裁切精度；引入多层级图像内存池机制提升动态更新效率,形成兼具精度与时效性的影像处理方案。实验验证表明,该方法在10GB级影像处理中裁切效率提升50%,拼接误差控制在0.3像素以内,为标准地图服务提供了高效、精准的技术支撑。
