摘　　要：传统航道渲染方法因缺乏周边地理要素和实时数据,导致其难以全面应用。为解决该问题,研究了一种大规模三维航道处理和渲染方法,整合了航道周边的静态和动态信息,实现了三维航道多模态渲染。在珠江口等区域进行验证,结果表明与插件或本地化方法相比,该方法显著提升了航道数据的利用效率,有助于提升航道管理水平。Traditional methods of navigation channel rendering lack the integration of surrounding geographical elements and real-time data,resulting in limited applications.To solve this problem,we researched a large-scale 3D navigation channel processing and rendering method,which could integrate static and dynamic information surrounding navigation channel and achieve the multi-modal rendering of 3D navigation channel.Verification in areas such as the Pearl River Estuary show that this method has significantly improved the utilization efficiency of navigation channel data compared to plugin or localization methods,contributing to the improvement of navigation channel management.
